Full textAbstract:
On 3 May 1954, Lehigh Coal and Navigation Company announced that it would close its anthracite mining operations in Pennsylvania's Panther Valley. Company officials had hoped to keep some mines open but net losses in 1953 amounted to $1.4 million and the trend continued into early 1954. The company stated they would reopen the mines only if miners would work harder and produce more. All area locals of the United Mine Workers of America (UMW) voted to accept the program except one, Tamaqua Local 1571. Arguing that the new rules violated existing wage agreements, workers from this Local picketed the mines and called on miners across the anthracite region to join them. Tamaqua miners offered an alternative plan that called for workers to share control over management and production decisions. Lehigh managers refused and closed the mines, effective from 30 June. As other mining companies began to collapse in the 1950s and 1960s, local workers, business owners, union leaders, and politicians made efforts to either open mines or attract new industries. However, unemployment remained a difficult problem for the Panther Valley and for the entire anthracite region and the area still exhibits higher than average unemployment.

India is in the list of fastest growing countries of the world. India's energy needs are also increasing due to population and industrial growth for improving quality of living style. In India, coal is major input infrastructure industries for example Power plants, Steel plants and Cement industries. India’s 52% of primary energy is coal dependent1. 66% of India's power generation depends upon coal production1. Jharia Coalfield (JCF) is falling in the Lower Gondwana Coalfields of India. The area of the JCF is about 450 km2. It is important for the major supply of precious coking coal required for steel plants in India. It is located in Dhanbad district of Jharkhand state of India, The latitude is 23° 39' to 23° 48' N and longitude is 86° 11' to 86° 27' E for the Jharia coalfield. Based on environmental parameters, all the 103 mines of BCCL have been grouped under 17 Clusters. A cluster consists of a group of mines with mine lease boundary lying in close vicinity and includes-Operating mines, Abandoned/ closed mines and proposed projects.The focused study area is in the western part of the Jharia coalfield is named as Cluster XV group of mines of BCCL consists of four mines, Kharkharee Colliery (UG), Dharmaband Colliery (UG), Madhuband Colliery (UG) and Phularitand Colliery (UG) .The present study was carried out with the objective to measure the ambient air quality of the study area with reference to particulate matter (SPM, PM10 & PM2.5). Ambient air monitoring results have shown that the observe air quality were found within the limit prescribed by MoEF / CPCB. It may due to Underground mines as there are pollution causing lesser activities involved in the UG mining process compared to opencast mining. Implementation of Master plan for Jharia coalfields for environmental management has also improve the air quality in the area10,11.

Full textAbstract:
Miners’ unsafe behavior is the main cause of roof accidents in coal mines, and behavior intervention plays a significant role in reducing the occurrence of miners’ unsafe behavior. However, traditional behavior intervention methods lack pertinence. In order to improve the intervention effect and reduce the occurrence of coal mine roof accidents more effectively, this study proposed a targeted intervention method for unsafe behavior. The process of targeted intervention node locating was constructed, and based on the analysis of 331 coal mine roof accidents in China, three kinds of targeted intervention nodes were located. The effectiveness of targeted intervention nodes was evaluated by using structural equation model (SEM) through randomly distributing questionnaires to miners of Pingdingshan coal. The results show that, in preventing roof accidents of coal mines, the targeted intervention nodes have a significant positive impact on the intervention effect. The method can also be applied to the safety management of other industries by adjusting the node location and evaluation process.

With continuous advancements in sensor technology, wireless communications, modern network architectures and electronics; it is now feasible to fulfill the requirements of underground mines using wireless sensor network (WSN). At present, coal mining industries have the option of choosing a communication and tracking systems based on their requirement and budget. WSN has the advantage of support for wireless architecture which may fit for mining industries. There is limited literature available, which discuss the different features and associated challenges to WSNs in underground mines. However, in this paper, WSN has been targeted as a feasible solution for the underground mining industries, and emphasis has been given on integration of comprehensive concepts. The objective of this survey paper is to present a platform such that it is not only beneficial for beginners who want to pursue research in this area, but also target current researchers developing solutions for such confined and hostile environments. Furthermore, the application of WSN for underground mines has been categorized followed by real, and simulation-based studies and the significant implications for wireless communications and monitoring systems in the underground mines have been discussed in details.

Full textAbstract:
From the days of primitive society, human and animals have used the resource of the earth to support life and to dispose waste. Rapid population growth and uncontrolled industrial development are seriously degrading the urban and semi-urban environment in many of the developing countries placing enormous strain on natural resources and undermining efficient and sustainable development. Industrial operations lead to considerable generation of hazardous waste and in rapidly industrializing countries such as India the contribution to hazardous waste from industries are largest. Hazardous waste genarations from industries is also critical due to their large geophysical spread in the country, leading to regionwide impacts. Due to liberalization policy the pace of industrialization has been accelerated, which has resulted in increasing amount of hazardous waste every year. This long with a growing amount of municipal solid waste due to rapid urbanization and inadequate policy and technological measures continues to remain a daunting issue of environmental concern to India. In this scenario the present paper discusses various aspects of hazardous industrial waste like its origin, distribution and environmental and health hazards. Hazardous waste from industrial sectors contains heavy metals, pesticides, radioactive materials and other chemicals, which are toxic, flammable, reactive, corrosive, or have explosive properties. Normally Arsenic, Cadmium, Chromium, Copper, Lead, Zinc, Boron etc are found in pulverized fly ash. Cement industries emit huge quality of fluoride into the environment. Large quantity of mercury emitted from caustic soda industries using mercury electrodes, from chemical industries, paper and pulp industries etc. Tin mines emit tin in the vicinity of the mines. The metals such as Cadmium, Lead, Chromium, Arsenic etc, if present in the body, are hazardous to the health. Presence of fluoride within the range of 0.5 to 1.5 ppm is very essential in water for health, if present in excess leads to Florosis. Fouride may cause harm not only through water but also through air by way of respiration and soil. In river estuaries, the concentration of metal traces will reach to a high degrees of contamination because of stagnant water, when industrial effluents are fed into rivers and streams. This paper throws light upon many more such factors and also suggest measures to control and manage hazardous waste.

Full textAbstract:
The article is devoted to the development of conceptual issues of the methodology for forming the readiness of miners for effective and safe activities in extreme situations in mines. The improvement of the efficiency of miners’ training is based on using the capabilities of digital educational technologies and the developed training complex. The article defines the competency structure of workers in hazardous industries, ensuring that they perform working functions in extreme situations and reduce the risk of their life and health in case of accidents. The problem factors in the system of professional retraining are researched. The psychological and pedagogical conditions for the success of the use of the training complex are determined. The main approaches to the formation of the content of theoretical and practical training are formulated. The structure of the training complex for the training of miners is described; the process of its adjustment and functioning is considered. The key stages of the developed methodology for the formation of readiness of miners for activities in emergency situations in mines are considered. Training, using the proposed methodology and training complex, has significantly improved the application of self-rescuers, which is confirmed by an increase in the time indicator of the protective effect of the breathing apparatus used by students after training on simulators.

JoAnn put down the inventory reports of four Mosaic mines that she had been contemplating. Much of the raw material for the company’s phosphate fertilizer production was mined and processed at these Florida facilities. Keeping track of the vast array of equipment, parts, and supplies required to operate the mines had become an issue. JoAnn Speaks, Purchasing Manager at Mosaic Company, was tasked in 2015 to implement a comprehensive system to identify, control and track the company’s inventories. A recent Sarbanes–Oxley (SOX) audit had found weaknesses in Mosaic’s inventory practices leaving it unable to adequately account for the disposition of millions of dollars of assets annually. Working closely with technology companies Motion Industries and CribMaster®, JoAnn had successfully implemented a radio-frequency identification (RFID) system at five Mosaic chemical facilities. The implementation experienced hiccups, but problems had been resolved and the benefits had quickly become apparent. Within two months of going live, losses were down 35% and time spent locating items was reduced by 160 man-hours per month at the pilot chemical facility. Once the chemical facility implementation process approached completion, JoAnn turned her attention to the mines. RFID was great for the static and centralized chemical facility operating structure, but would it be successful in the mines? Although each mine had a central warehouse facility, equipment and numerous inventoried, critical-to-operations components were also spread across many square miles to minimize downtime in the event of a failure. This created environmental and connectivity issues that would have to be overcome to use RFID. With all the additional options available outside of RFID including vending, inventory centralization and even manpower additions, what was going to be the right single or combination of solutions? Or, was there something she hadn’t yet considered? The only sure thing was the SOX audit meant the status quo was not an option. JoAnn picked up the reports and leaned back in her chair as she considered the strengths and weaknesses of the possible solutions and decided what to do next.

In mine safety and health research, psychological issues have always been neglected. This paper aims to identify the psychological perceptions of workers with respect to the mine environment and interpersonal environment across the whole production system. A survey was designed that measured the miners’ demographic details and perceptions of two affect-based interactions; three resource-based interactions for the manager, supervisor, co-worker; and three actual environment interactions. A total of 642 frontline coal miners from six mines located in six provinces in China completed the survey. The main results indicated that that miners reported low psychology status, especially those over 51 years old, with a monthly income of 2000–4000 and junior school education. Second, there was a high proportion of inferior value in environmental interactions. Meanwhile, the miners’ interactions with their co-workers were perceived as the most positive and those with their managers as the least in interpersonal interactions. Third, there were significant differences in sub-dimension interactions (actual environment, resource-based, affect-based interactions) that certainly existed in these interactive roles. Additionally, the dissociated type of miners with manager and supervisor (low resource and affect-based interaction) reached 23.99~24.45%. This study revealed the inner psychological risk factors for safety and health work in coal mines and provides an essential guideline for mining industries.

Full textAbstract:
Operations of mining are large industrial scale in nature, with significant environmental impacts. The mining industry generates and produces wastes containing high concentrations of metals and metalloids which are highly toxic and destructive to the immediate landscape and environment. In addition, the continued use of the traditional methods of mining intensifies the emission of toxic and products that are not friendly to the ecosystem.. Even regulated and controlled mining sites release toxins into the surrounding environment. While mining has prospects and benefits to the economy, both in terms of its own economic impact and the value to other industries of its product, it almost always has adverse environmental impacts and eventually health impacts. There are numerous ways in which mines impact the health of nearby environments and local communities. Mining involves some generally standard processes and practices. This paper considers the effects and harm done to living things around the mine location. By understanding mining’s threats to health and long-term well-being and by taking precautions to reduce harm in all mines, miners and other people in mining communities can better protect their health and improve their lives. This research will address questions like: which are the toxic substances causing health problems in Maiganga Coal Mine? What is the challenging impact of toxic substances in Maiganga coal Mine?

Chronology models based on radiotracers are useful for dating aquatic sediments influenced by industrialization. Among the many natural (e.g. 7Be, 234Th,210Pb) and artificial (e.g. 137Cs,238,239,240Pu) radiotracers, the proper ones to study the industrial impact and reconstruct past events during the last 100 years, are 210Pb and 137Cs. Mining belongs to the industries with great ecological impact in the aquatic environment, as mines are situated near environmental sensitive areas such as coasts, rivers and lakes. Additionally, the accurate historical reconstruction may provide information regarding the mine footprint in the aquatic environment so as to assess the previous or the remaining contamination, in case of on-going or abandoned mines. In the present study, the retrospective investigation in a coastal area of Lavrio, near an abandoned metallic mine is attempted, using the 210Pb and 137Cs methodologies and the emerged difficulties are discussed.

Every year, the problem of industrial safety is becoming increasingly relevant. The effective industrial safety management system (ISMS) organization becomes especially important for nuclear energy, chemical, petrochemical, oil and gas, mining, metallurgical industries, coal mines and other industries, including enterprises with hazardous production facilities (HPF). Any violation of operating modes, unaccounted technological and operational defects can lead to serious consequences and accidents, accompanied by significant material costs and technological disasters. An important place among the problems of industrial safety is the problem of trouble-free operation of technical devices (units, machines and mechanisms, technical systems and complexes, technological equipment, instruments and apparatus) of hazardous production facilities. However, existing approaches to solving this problem have limited application. The article proposes an effective solving method of the problem based on the use of graph models. The advantage of such modelling is the simplicity, clarity and ease of mathematical algorithmization of the studied production processes and technical systems.

limestone is one of the sedimentary rocks and one of the most extended materials of this group which is widely used for production of cement, glasswork industries, tile making and heat resistance. Therefore, a research experiment was conducted in 2020 at of Poz-E- Wazirabad and Qachandara of Samangan province in Afghanistan to compare the similarity and the differences of petrographic characteristics and chemical composition of limestone in both mines. The samples were taken from both the mines for spectrometric analyses at directorate of laboratories of ministry of mining. Besides, the slides were prepared from these samples and the mineral composition, structure and texture characteristics were studied under petrographic microscope in laboratory of Geology and Mines of Kabul Polytechnic University. The main objectives of this study were to know the similarities and differences in petrographic characteristics and chemical composition of both mines, which in case of more similarities and favorability of Qachandara limestone mine; it would be suggested as a good source for establishment of a cement factory and other dependent industries on limestone in this province. The results indicated a lot of similarities with minor differences in both the mines. The minor differences were the amount of calcium oxides which was 52.54% in Poz-E-Wazirabad which was reduced in Qachandara mine to 47.81%. The magnesium content of Qachandara limestone was about 4% richer than Poz-E-Wazirabad limestone mine. The Poz-E-Wazirabad limestone was white in color while the Qachandara limestone color was gray to black, which shows the existence of organic matter in composition of this mine. The structure of limestone in Wazirabad mine was biomorphic but the limestone structure in Qachandara mine was oolitic.

Full textAbstract:
By the 1930s, silicosis – a debilitating lung disease caused by the inhalation of silica dust – had reached epidemic proportions among miners in the gold-producing Porcupine region of northern Ontario. In response, industrial doctors at the McIntyre Mine began to test aluminum powder as a possible prophylactic against the effects of silica dust. In 1944, the newly created McIntyre Research Foundation began distributing aluminum powder throughout Canada and exported this new therapy to mines across the globe. The practice continued until the 1980s despite a failure to replicate preventative effects of silicosis and emerging evidence of adverse neurological impacts among long-time recipients of aluminum therapy. Situated at the intersection of labour, health, science, and environmental histories, this article argues that aluminum therapy represents an extreme and important example where industry and health researchers collaborated on quick-fix “miracle cures” rather than the systemic (and more expensive) changes to the underground environment necessary to reduce the risk of silicosis.

Full textAbstract:
The exploration and mining of Nigerian barite are primarily by artisanal and small-scale miners (ASM) whose operations are characterized by poor productivity. As a result, the quantity and quality of barites produced do not satisfy the nation’s oil sector demands and other industries that require the mineral. This situation leads to massive importation of the mineral with negative impact on the country’s drive toward increasing the contribution of solid minerals to the gross domestic product (GDP). This study reviews the existing policies and government interventions on ASM of Nigerian barite; evaluates the operations of ASM through a survey of mines in Nasarawa state, Nigeria; identifies factors that affect sustainability of the sector and proffers solutions to foster sustainability of ASM of barite in the region. The study adopted the 4Is optimization technique (Information gathering, Interpretation, Implication, and Implementation) through personal interactions with the stakeholders at the barite mining sites, and government agencies, regarding policies and interventions specific to ASM of barite. Challenges identified include: weak implementation and enforcement of mining laws; inadequate support from government and development partners; poor access to mining equipment and technology; poor infrastructure (access road, water, electricity); poor pricing of products (marketing challenges); poor remuneration of mine workers; poor mining skills; inadequate formal education; limited awareness on environmental health and safety hazards; fragility and conflict; insufficient information and data on mines and miners; security issues; lack of access to finance; lack of formalization of operations and poor legal framework for operations. The strategies suggested for fostering the sustainability of ASM of barites include: enhanced policy and legislation formulation and implementation, strengthening of institutions, formalization of ASM operations, training of miners, awareness campaign, improvement in environmental and safety of operations, empowerment and support by government and development partners for individual miners and processors and organized groups within the sector (such as Miners Association of Nigeria, Association of Miner and Processors of Barite, AMAPOB). Implementation of these strategies will lead to sustainable operations of the sector and hence improved rural livelihoods, stimulation of entrepreneurship in an environmentally responsible manner, and improvement in the contribution of the mineral sector to the nation’s gross domestic product (GDP), and hence national development.

Full textAbstract:
The presented work provides a comprehensive inventory of data on closed (or in closing phase) and abandoned underground and surface mines and mining waste sites in Slovenia, collected within the framework of the Geological Survey of Slovenia (GeoZS) over the last two decades. Furthermore, a detailed overview of information on closed and abandoned mining waste sites in Slovenia is given. In order to establish the inventory, a definition of the work methodology, a comprehensive research of the archived and published literature, and the harmonisation and management of the collected data was carried out. Based on a selected methodology, the inventory contains information on 33 metal mines, 43 coal mines, 51 non-metallic mineral resource mines, 156 waste sites from metal mines and 18 waste sites from coal mines. The inventory is in the open access Google Earth file. It provides a basis for further research into the environmental impact of mining waste, which has been carried out since the EU Directive on the management of waste from extractive industries (Directive 2006/21/EC hereafter) was adopted into national law. In general, about 11,621,333 m3 of waste sites from metal mines and 76,188,000 m3 of waste sites from coal mines are covering about 678 hectares of Slovenian territory. More than half (64 %) of the waste from metal mines was produced in the Mežica lead and zinc mine, while the other two mines with a still significant share of produced waste were the Idrija mercury mine (18 %) and the Žirovski vrh uranium mine (15 %). Among the closed coal mines, the largest amount (46 %) of waste was generated by the coal mine Trbovlje-Hrastnik, while the other two coal mines with still significant share of waste produced were Kočevje (28 %) and Kanižarica (17 %).

Full textAbstract:
The study addresses the socio-economic development of the Suchan coal mine, the oldest coal-mining enterprise in the Russian Far East; it draws on archival sources in order to highlight the pages of history of the coal industry in the region. Taking into account the results of their predecessors’ work, the authors study the characteristic features of the coal industry development in the Far East under the conditions of the New Economic Policy of the Soviet state. There was a lack of diversified assistance from the Center, while the attention of the party elite to the resources of extractive industries increased: these were traditionally redirected for the needs of the Western regions or exported. The novelty consists in a comprehensive study of the development of the Suchan mine in the 1920s in the context of political and socio-economic situation in the country and the region. The study shows the role of central and local authorities at the stage of reconstruction of the coal industry, the participation of trade union organizations in the formation of labor collectives in the Suchan. It considers the mechanism of regulation of ‘collective agreement relations, the participants of which were the miner trade union and the Suchan mines. Analysis of the socio-economic development of the coal mining enterprise in the era of transformation contributes to formation of ideas about the material and living condition of the miners. The causes of unstable social situation in the Suchan mines are revealed in the context of social policy of the Soviet state. There were problems with wages and unsettled system of coal mining prices, which repeatedly became a cause for conflict between the coal hewers and the administration, attempting to avoid strikes. The social image of the Suchan workers has been reconstructed: they were mostly from rural areas and kept a close connection with the village. The unsolved housing problem had an impact on the miners’ way of life. It is concluded that with completion of the restoration of the industrial sector of the Soviet Far East economy, the model of state patronage over the region had been established; alongside with military and strategic tasks, it focused on the coal industry. However, the complex of social and household problems of the Suchan miners remained unsolved.

With the continuous development of Artificial Intelligence technology and Internet of Things engineering, more and more driver-less vehicles have been developed and put into industrial production. The birth of driver-less vehicles undoubtedly brings new vitality to a large amount of industries, particularly in transportation. For the mining industry, transportation is undoubtedly an extremely important link in the whole production process. If the driver-less vehicles can be applied to the underground mines, it can not only improve the production and transportation capacity of the whole mine but also can reduce the occurrence of many mine safety accidents. ZigBee WSN technology can play a greater role in the narrow environment such as underground mines according to the relevant literature; this concept paper, similar to an engineering project plan, mainly tries to integrate the ZigBee WSN technology and the communication-based train control (CBTC) system to explore the possibility of the driver-less vehicles to be used in the underground mines, which aims to solve practical engineering problems for the engineering projects. As the mining engineers, we put forward the concept of this integrated system in this concept paper, but we need to continue to work hard for the future of the underground mines. This concept paper serves as a guide to Tossing out a brick to get a jade gem, and it has a few implications for the development of underground mine transportation.

Full textAbstract:
Mining is an age-old industry that has propelled human progress and development. Despite India‟s economic prowess and richness in minerals, its mines are plagued with inefficiency and lack modern technology. In countries with well-developed mining industries, automation has proven to be a beneficial technology. Incorporating modern technologies into Indian mines is a challenging task due to many factors unique to the country. This study establishes the benefits of automation by discussing the Australian mining industry. A clear insight into the socio-cultural challenges to be faced while modernizing the Indian mining industry, focusing on automation, is presented using an interpretive approach, relying mainly on qualitative data in existing texts. The study conveys the significance of these obstacles and proposes new government bodies and schemes to overcome them. Finally, further work on this less discussed topic is motivated by mentioning areas for future consideration.

In the Bathurst Mining Camp (BMC), 12 of the 45 known massive sulphide deposits were mined between 1957 and 2013; one was mined for iron prior to 1950, whereas three others had development work but no production. Eleven of the deposits were mined for base metals for a total production of approximately 179 Mt, with an average grade of 3.12% Pb, 7.91% Zn, 0.47% Cu, and 93.9 g/t Ag. The other deposit was solely mined for gold, present in gossan above massive sulphide, producing approximately one million tonnes grading 1.79 g/t Au. Three of the 11 mined base-metal deposits also had a gossan cap, from which gold was extracted. In 2012, the value of production from the Bathurst Mining Camp exceeded $670 million and accounted for 58 percent of total mineral production in New Brunswick.Base-metal production started in the BMC in 1957 from deposits at Heath Steele Mines, followed by Wedge in 1962, Brunswick No. 12 in 1964, Brunswick No. 6 in 1965, Caribou in 1970, Murray Brook, Stratmat Boundary and Stratmat N-5 in 1989, Captain North Extension in 1990, and lastly, Half Mile Lake in 2012. The only mine in continuous production for most of this time was Brunswick No. 12. During its 49-year lifetime (1964–2013), it produced 136,643,367 tonnes of ore grading 3.44% Pb, 8.74% Zn, 0.37% Cu, and 102.2 g/t Ag, making it one of the largest underground base-metal mines in the world.The BMC remains important to New Brunswick and Canada because of its contributions to economic development, environmental measures, infrastructure, mining innovations, and society in general. The economic value of metals recovered from Brunswick No. 12 alone, in today’s prices exceeds $46 billion. Adding to this figure is production from the other mines in the BMC, along with money injected into the local economy from annual exploration expenditures (100s of $1000s per year) over 60 years. Several environmental measures were initiated in the BMC, including the requirement to be clean shaven and carry a portable respirator (now applied to all mines in Canada); ways to treat acid mine drainage and the thiosalt problem that comes from the milling process; and pioneering studies to develop and install streamside-incubation boxes for Atlantic Salmon eggs in the Nepisiguit River, which boosted survival rates to over 90%. Regarding infrastructure, provincial highways 180 and 430 would not exist if not for the discovery of the BMC; nor would the lead smelter and deep-water port at Belledune. Mining innovations are too numerous to list in this summary, so the reader is referred to the main text. Regarding social effects, the new opportunities, new wealth, and training provided by the mineral industry dramatically changed the living standards and social fabric of northern New Brunswick. What had been a largely poor, rural society, mostly dependent upon the fishing and forestry industries, became a thriving modern community. Also, untold numbers of engineers, geologists, miners, and prospectors `cut their teeth’ in the BMC, and many of them have gone on to make their mark in other parts of Canada and the world.

AbstractMining industry is currently one of the biggest industries in the world. All mines produce “indispensable” minerals, starting from fuels such as coal and ending with noble metals such as gold or copper. Mines in the world compete in the volumes of mined minerals what requires use of state-of-the-art, more efficient and, and what is more important, safer machines. Such trend favors development of technology and mobilize engineers to adapt the technologies that were used so far in easier environment to the needs of the mining industry.The article presents the issue of energy recuperation in mining battery locomotives. Simulation tests of the power supply and control system of the Lea type battery locomotive are discussed. The results of tests on the electric energy consumption of the locomotive during the operational change in the mine were presented, which were referred to the simulation results. Factors influencing the efficiency of energy recovery and the risk resulting from hydrogen emission in the recuperation process have been indicated. Also discussed is the study of the concentration of hydrogen concentration emitted from the battery of lead-acid cells during their recharging in the process of electrical braking with energy recuperation.

Along with the folk crafts of the Transcarpathian region, an industrial tour is being developed in conjunction with industrial and natural objects that make up its resource potential. In the context of reforming economic relations, the emphasis is on the development of priority economic sectors – the forest and wood industry, light and food industries, the development of cross-border cooperation, recreation and tourism, etc. The main attention is paid to the further restructuring of the entire national economic complex, the involvement of domestic and foreign investments in the economy, the development of small and medium-sized businesses, and the effective use of natural resource potential. It is proved that the condition of full awareness of tourists is the creation of a passport of an industrial tour, which includes ecological, technical, and cadastral. Tours on mines from salt mining, precious metals, sulfur mines, oil wells, mineral water, ozocerite, objects of the former military complex – rocket mines, storage facilities, warehouses, enterprises for processing raw materials and materials, folk crafts are promising the direction of development of industrial tourism in Transcarpathia. Industrial tourism, as part of the overall tourist process in Ukraine, can be directed at solving many socio-economic tasks of local communities, the most important among them is increase of employment, growth of its welfare, provision of socio-cultural development of the region and improvement of quality of life of people. Today, in order to increase the competitiveness of the region in the tourism industry, the cluster method, which was previously used only in industrial production, is used. A tourist cluster [5] is a key organizational framework that combines tourism and other related industries into a single system that enables the enterprises, institutions and organizations to meet the priority objectives and enhance the competitive advantages of the region. By creating such an association, financing and implementation of even very ambitious projects in the tourism sector could be provided, which would otherwise be impossible for each individual participant. The developed map of the territorial placement of centers of industrial tourism in the Transcarpathian region greatly simplifies the creation of an informative cadastral system and on its basis industrial tours. At the same time, the improvement of this system requires the systematic introduction of new information indicators, taking into account the change in structural and functional relationships between different departments. In general, Transcarpathia has an all-Ukrainian significance in the economic plan as a region with significant potential of the forest and wood industry, winemaking, vegetable growing, dairy industry, tobacco production, mineral waters.

Full textAbstract:
The provision of the energy system of Ukraine with a stable supply of coal in the long term demands calculation of the capacity of the exploitable deposits. Ukrainian deposits are characterized by insignificant thickness and complicated mining-geological conditions, which significantly complicates the mining process. Therefore, it is necessary to develop and use new energy-efficient technologies of coal mining. The article evaluates the criteria of usefulness of thin layers of deposits in the Western Donbass, which contains 25 bn t of coal, i.e 21.3% of total resources of the country, for processing in selective technology. According to the geologicstructural factor, we distinguished the fields of mines of hydrodynamically “open” and “close” types, the water inflows of which differ by a factor of ten. Taking the example of the mines of the east group, we ascertained the potential of the most promising coal reserves, which are appropriate for mining using selective technology. It was established that in these conditions, selective technology of coal excavation would not only allow a decrease in the ash content of the coal output, but would also prolong the period of the industries` operation. Backfilling of mined-out areas decreases the technogenic load on the underground and surface hydrosphere, decreases the subsidence of the surface and the volume of waste rocks.

Purpose This paper aims to propose a model to assess leagile strategy effectively as one of the most discussed production and supply chain strategies. Design/methodology/approach This research is based on an integrated FLinPreRa-FQFD approach, which ranks and determines the importance of criteria and indices of the proposed model in an effective way. Findings “Cost” has been taken as the most important competitive advantage in the four selected industries. “Customer and market sensitiveness” has been considered as the most important enabler in three industries (“machinery and equipment,” “textile” and “food and beverage”). “Collaborative relationship” has been also considered as the most important enabler in the “material and chemical products” industry to gain leagility. Practical implication On the one hand, the proposed research model can be used as a reference guide for firms to reach leagility. This model presents indices of leagility at different levels. On the other hand, with respect to the main activities of the Iran Chambers of Commerce, Industries, Mines and Agriculture, including Qazvin’s, committed to provide requirements for economic development, this work provides an opportunity for the implementation of leagility model in 151 active companies. It also gives new insights into the leagility application in the four industries and Qazvin’s Chamber of Commerce, Industries, Mines and Agriculture. Originality/value This research has two main contributions. First, it presents a model of enablers and attributes of leagility, combined with four competitive advantages. Second, the research study is equipped with an integrated and consistent methodology that, first, helps decision makers prioritize their goals and agenda by means of fewer paired comparisons without the need of consistency rate and, second, allows for direct evaluation of impact of enablers on attributes of leagility.

Stochastic simulation was conducted to analyse the fuel consumption of a shovel-truck system. An example shovel-truck system, comprising a single shovel and four trucks was considered. At 95% confidence interval, the monthly simulated fuel consumption by the shovel-truck system was found to be about 198 127 litres against the actual fuel consumption of 203 772 litres, registering a variance of -2.70%. About 22 000 litres of fuel was consumed per month due to truck waiting. Optimising the fuel consumption and truck waiting time can result in significant fuel savings. The paper demonstrates that stochastic simulation is an effective tool for optimising the utilisation of fossil-based fuels in mining and related industries.

The objective of this study was to find opportunities for metal waste recycling in the process of rock breaking in mines. A built-up cutter design for a combined cutter-loader and a recycling technique for a considerable portion of the deteriorated tool are suggested. Industrial tests have proven the possibility of a ten-fold increase in the use of cutters on mining machines for coal rock mass destruction. The proposed technique allows a four times reduction in metal consumption in the production and use of cutters and a reduction of the ultimate resulting waste by 80%. This advanced technique could be transferred extensively into such industries as open-cast mining, repair of motor-roads, construction and agriculture.

Full textAbstract:
Industrial development within Canada’s boreal zone has increased in recent decades. Forest management activities, pulp and paper operations, electric power generation, mining, conventional oil and gas extraction, nonconventional oil sand development, and peat mining occur throughout the boreal zone with varying impacts on water resources. We review impacts of these industries on surface water, groundwater, and wetlands recognizing that heterogeneity in the dominance of different hydrologic processes (i.e., precipitation, evapotranspiration, groundwater recharge, and runoff generation) across the boreal zone influences the degree of impacts on water resources. Through the application of best management practices, forest certification programs, and science-based guidelines, timber, pulp and paper, and peat industries have reduced their impacts on water resources, although uncertainties remain about long-term recovery following disturbance. Hydroelectric power developments have moved toward reducing reservoir size and creating more natural flow regimes, although impacts of aging infrastructure and dam decommissioning is largely unknown. Mineral and metal mining industries have improved regulation and practices, but the legacy of abandoned mines across the boreal zone still presents an ongoing risk to water resources. Oil and gas industries, including non-conventional resources such as oil sands, is one of the largest industrial users of water and, while significant progress has been made in reducing water use, more work is needed to ensure the protection of water resources. All industries contribute to atmospheric deposition of pollutants that may eventually be released to downstream waters. Although most industrial sectors strive to improve their environmental performance with regards to water resources, disruptions to natural flow regimes and risks of degraded water quality exist at local to regional scales in the boreal zone. Addressing the emerging challenge of managing the expanding, intensifying, and cumulative effects of industries in conjunction with other stressors, such as climate change and atmospheric pollution, across the landscape will aid in preserving Canada’s rich endowment of water resources.

Small scale mining industry is considered more hazardous than other industries worldwide. Large number of workers receive minor and major injuries leading to disabilities or loss of lives due to frequent accidents in mines. Main causes of accidents in mines are fall of roof, improper ventilation system, gases, fires and mine explosions. Beside these hazards, violation of rules and regulations for mine workers are common, which also cause accidents. This paper is focused on issues associated with the health and safety of workers of Cherat Coal Mines (CCM), Abbottabad Coal Mine (ACM) and Abbottabad Soapstone Mine (ASM), Pakistan. The collected data were analyzed with SPSS computer statistics software. The data analyses indicated that the lack of education and violation of safety laws cause accidents in mines. Results show that problems that were rated higher by more than 60% of workers included slide and fall, dust, roof fall and explosive related hazards. In survey more than 50% of the workers admitted the existence of gases, fire and low height mines are common hazards in their workplace. The results also indicated that not only workers but management are also affected by accidents. More than 17% of worker in CCM faced serious accidents up to 3 times during one year. Up to 26% of workers in CCM, 13% in ACM and 15% in ASM suffered accidents for which they had 3 workdays off. It has been concluded that training should be arranged, especially the safety related training on regular basis to reduce the risk of accidents.

Eco-Efficiency emerged in the 1990s as a measure of "the efficiency that ecological sources use to meet human needs." As a tool in economic and environmental integration, Eco-efficiency needs to be promoted further so that regulation in government and industrial management can include it as an important instrument. This paper provides several approaches that can help various industries to develop effective eco-efficiency principles. The approach used is to maximize the role of the Steering Committee of the company's internal environment. Utilization of natural resources such as water, forests, mines and energy needs need to be balanced with Eco-Efficiency so that natural exploitation can be well controlled so that sustainable development aspired by the world can be realized.

Functional link-based neural network models were applied to predict opencast mining machineries noise. The paper analyzes the prediction capabilities of functional link neural network based noise prediction models vis-à-vis existing statistical models. In order to find the actual noise status in opencast mines, some of the popular noise prediction models, for example, ISO-9613-2, CONCAWE, VDI, and ENM, have been applied in mining and allied industries to predict the machineries noise by considering various attenuation factors. Functional link artificial neural network (FLANN), polynomial perceptron network (PPN), and Legendre neural network (LeNN) were used to predict the machinery noise in opencast mines. The case study is based on data collected from an opencast coal mine of Orissa, India. From the present investigations, it could be concluded that the FLANN model give better noise prediction than the PPN and LeNN model.

Full textAbstract:
Rare earth elements (REEs) are widely used in various industries. The open-pit mining and chemical extraction of REEs in the weathered crust in southern Jiangxi, China, since the 1970s have provoked severe damages to the environment. After 2010, different restorations have been implemented by various enterprises, which seem to have a spatial variability in both management techniques and efficiency from one mine to another. A number of vegetation indices, e.g., normalized difference vegetation index (NDVI), soil-adjusted vegetation index (SAVI), enhanced vegetation index (EVI) and atmospherically resistant vegetation index (ARVI), can be used for this kind of monitoring and assessment but lack sensitivity to subtle differences. For this reason, the main objective of this study was to explore the possibility to develop new, mining-tailored remote sensing indicators to monitor the impacts of REE mining on the environment and to assess the effectiveness of its related restoration using multitemporal Landsat data from 1988 to 2019. The new indicators, termed mining and restoration assessment indicators (MRAIs), were developed based on the strong contrast of spectral reflectance, albedo, land surface temperature (LST) and tasseled cap brightness (TCB) of REE mines between mining and postmining restoration management. These indicators were tested against vegetation indices such as NDVI, EVI, SAVI and generalized difference vegetation index (GDVI), and found to be more sensitive. Of similar sensitivity to each other, one of the new indicators was employed to conduct the restoration assessment of the mined areas. Six typically managed mines with different restoration degrees and management approaches were selected as hotspots for a comparative analysis to highlight their temporal trajectories using the selected MRAI. The results show that REE mining had experienced a rapid expansion in 1988–2010 with a total mined area of about 66.29 km2 in the observed counties. With implementation of the post-2010 restoration measures, an improvement of varying degrees in vegetation cover in most mines was distinguished and quantified. Hence, this study with the newly developed indicators provides a relevant approach for assessing the sustainable exploitation and management of REE resources in the study area.

Abstract Thallium is highly toxic but has been an obscure element compared to its three popular neighbours, lead, mercury and cadmium. It is partly due to the scarcity of its analytical data, caused by its high analytical detection limit relative to the other three elements and by its generally low level in the environment. We have developed a highly sensitive instrument, a Laser-Excited Atomic Fluorescence Spectrometer, to study thallium contamination in some important Canadian ecosystems from the Arctic (containing very low thallium concentration) to coal-related industries across Canada and even to the study of thallium toxicity in an invertebrate, Hyalella azteca. Overall, our data indicate that the coal power plants and mines contain higher thallium concentrations than the other ecosystems studied, and the eastern region has the highest Tl concentrations compared to other regions. The range of thallium concentration in ng/L for the Arctic snow and ice was between not detected and 8.4, for the Great Lakes waters 0.9 to 48, for pore waters 0.1 to 213, for western coal power plants and mines 0.1 to 1326, for central coal power plants 1.2 to 175, for eastern coal power plants and mines 0.2 to 23605, and for miscellaneous sites across Canada not detected to 4390 ng/L. Some of these high concentrations and those high ones reported in industrial wastewaters exceeded the chronic toxicity endpoints for Hyalella azteca mortality, growth and reproduction, thus can cause serious distress to the environment. All data were integrated into a map of thallium distribution, the first one in Canada. Natural background level of thallium for the Arctic was estimated to be 0.02 to 0.03 pg/g.

The need of developing appropriate noise prediction models for finding out the accurate status of noise levels (>90 dBA) generated from various opencast mining machineries is overdue. The measured sound pressure levels (SPL) of equipments are not accurate due to instrumental error, attenuation due to geometrical aberration, atmospheric attenuation etc. Some of the popular noise prediction models e.g. VDI and ENM have been applied in mining and allied industries. Among these models, VDI2714 is simple and less complex model. In this paper, a neuro-fuzzy model is proposed to predict the machinery noise in an opencast coal mine. The proposed model is trained with VDI2714 and the model output is seen very closely to matching with VDI2714 output. The model proposed has a mean square error of 2.73%. This model takes CPU time of nearly 0.0625 sec where as it takes 0.5 sec for VDI2714 i.e. approximately twelve times faster.

Full textAbstract:
for settlements located near mines and quarries, it is often necessary to zoning areas that are affected by mining operations. Most often, their influence is manifested in the form of subsidence of the earth's surface, sometimes sinkholes. It is particularly relevant for the "factory-type" towns of the Urals, where historically industrial settlements developed together and on the basis of mining and metallurgical industries, often having common borders. After decades, and sometimes centuries, the justified and safe use of these territories causes serious problems due to fragmentation and lack of information about their condition. A similar problem was encountered by the Berezovskiy town in the Middle Urals, most of whose territory was undermined. The closure and subsequent flooding of part of the mines of the previously city-forming gold mine led to the need to study its territory. To do this, a method was developed and zoning was performed in a step-by-step manner in the geoinformation system, and the consequences of flooding were established. In the process of implementation, all the engineering-geological, geodetic and other information provided by the mine was used. The results are unique due to the uniqueness and heterogeneity of the parameters of underground workings, sinkholes on the earth's surface caused by workings that are densely located on the studied territory.

Full textAbstract:
Underground mining, like many high-risk industries, is facing a crisis in the near future. This industry has traditionally relied on a master–apprentice relationship to train new workers, but experienced miners are retiring in large numbers, leaving few“masters” to properly train their replacements. With a recent resurgence in mining, many new miners are entering the workforce each day. The rise in the number of inexperienced workers has implications for worker safety in an industry in which one mistake can blow up the entire workplace. The explosion in the Darby Mine in May 2006 that killed five miners illustrates what can happen in hazardous environments such as underground mines. The Health Communications Team at the National Institute for Occupational Safety and Health Spokane Research Laboratory was asked to address this problem by developing new training and safety awareness materials to promote safe flame cutting and welding practices. This article describes how occupational ethnographic techniques provided insights needed for“new product development.” The result of this work was a national initiative to raise awareness and to protect underground coal miners from the dangers of flame cutting and welding in an environment filled with solid fuel and methane (natural gas). Although this project was initially designed for the mining industry, the approach and lessons learned are applicable to any high-risk industry and should be of interest to other social marketing or occupational safety and health professionals.

Full textAbstract:
Caustic Magnesia is also known as reactive magnesia. In the present study, process has been developed for recovery of caustic magnesia from kimberlite waste of Panna Mine. Panna Diamond Mining Project is the only mine in the country producing diamond. This is an open cast mine producing about 84000 carats diamonds per annum. About 100 tones of kimberlite have to be processed to get 10 carats (2 grams) of diamonds. Thus, about 0.9 million tons of kimberlite waste is being generated annually. Around 6-7 million tons of kimberlite waste is already available at Panna Mines, accumulated over the years waste during mining. Therefore, there is a need to look for development of bulk usage from the kimberlite. Technological option for Eco- friendly & Economically Efficient has to develop. In view of their wide application, and bulk usage, the caustic magnesia was identified to be developed from Kimberlite. Recovery of caustic magnesia from kimberlite tailing of Panna Diamond Mine is a novel chemical process, to prepare caustic magnesia from waste material. The process comprises i) Leaching, ii) filtration of leach liquor, iii) Precipitation of filtrate to get R2O3 and filtrate, iv) Precipitation of magnesium hydroxide, v) Washing and drying of magnesium hydroxide precipitate to remove sodium ions and surface moisture, vi) Calcinations of dried Magnesium hydroxide to get caustic magnesia which can be used in pharmaceutical industries, as animal feed, Mg metal etc.

Full textAbstract:
Prediction of pillar stability is one of the most critical tasks in underground mining industries. This pillar stability analysis requires many input parameters and some of them are difficult to be determined. Various statistical based analysis is presented in literature for assessing pillar stability successfully. In the present work, the data from three mines had been to determine the factor of safety. A total of 63 pillar cases had been collected from the mines. Principal component analysis (PCA) and Stepwise selection and elimination (SSE) models were developed by using multi variate linear regression (MLR) on 45 data sets and subsequently the proposed models were validated on 18 different data sets. The value of coefficient of determination (R2) is 0.86 and 0.84 for PCA and SSE respectively. The root mean square error for PCA and SSE are found to be 0.112 and 0.123 respectively. On validation of the proposed model developed by PCA and SSE, the PCA model provided a better validation results. Hence, PCA is recommended for modelling pillar stability.

Full textAbstract:
Technological revolutions are special moments of paradigmatic shifts, when the old industrial branches are still needed, but they go away, and the new industries have already manifested itself, but have not yet received proper business support. In modern conditions the economic problems of coal mines coincide with the toughening of the sustainable development ensuring requirements, which leads to the collapse of the industry under the pressure of energy in renewable sources. The authors since the nineties of the twentieth century are promoting the idea of introducing economic-organizational hierarchies, such as industrial parks, in the coal industry, for example, the scheme of corporate development of the mine field, according to which a private company at the state mine develop own piece of mine field, and the state enterprise provides the company with paid services for lifting, transportation, ventilation, drainage, power supply, sanitary and hygienic maintenance of personnel. This resulted in the purpose of the article – the justification of the expediency of the hierarchies in the coal industry in the situation of the modern industrial revolution. The research by methods of scientific abstraction, analysis and synthesis leads to a non-trivial solution to the comprehensive coverage of degrading and emerging industries. For example, there is the industrial park formed on the mine with accumulation of energy, which are necessary for the functioning of energy in renewable sources. Such parks should act as a kind of parachute for the enterprises of the "falling" coal industry and as a "booster" for the most modern power engineering. The clusters of industrial parks as the energy hubs in the mining regions provide the opportunity to diversify the activity of coal enterprises and find a solution of a large number of economic and social problems.

Full textAbstract:
La mise en valeur des richesses naturelles du Bouclier canadien au cours des années 1918-1938 a consacré la vocation industrielle du Québec. Avec les industries du papier, les mines et surtout l'industrie hydro-électrique, le Québec est entré dans une deuxième phase d'industrialisation à caractère nettement continental. Ces industries, en effet, en raison même des ressources qu'elles mobilisaient et des marchés qu'elles exigeaient, étaient entraînées à une exploitation à l'échelle nord-américaine. Entrée relativement tard dans le courant du nouvel industrialisme, la province de Québec y entrait quand même en son temps, c'est-à-dire, à un stade de développement technologique où l'entreprise américaine découvrait chez elle des ressources appropriées aux besoins des grands centres métropolitains de l'Amérique du Nord. Ainsi la province s'est industrialisée sous l'impulsion des foyers de développement des États-Unis, avec des capitaux importés des États-Unis, à l'aide de techniques qui n'étaient sans doute pas exclusives aux États-Unis mais qui furent véhiculées au Canada par des équipes d'ingénieurs américains et adaptées aux conditions canadiennes par des cadres préparés aux États-Unis. En d'autres termes, c'est des États-Unis que lui sont venus le capital financier et ses rouages de gestion, le génie d'entreprise et les cadres de l'administration. La province offrait à l'entreprise américaine des matières brutes et des manœuvres. Par dessus tout, elle s'engageait à collaborer avec l'entreprise américaine en lui procurant des conditions favorables d'exploitation. On comprend aujourd'hui les réticences de certains groupes du Québec pour qui un tel engagement évoquait l'image d'un nouveau pacte colonial, style XXe siècle. Ce nouveau régime industriel étayé par les États-Unis se manifeste dès la fin du XIXe siècle mais il ne se réalise pleinement qu'une vingtaine d'années plus tard, du moins dans la province de Québec. Dans la Colombie britannique, la grande exploitation minière de la région de Kootenay débute à la fin du XIXe siècle en liaison avec l'entreprise américaine. Dans l'Ontario, à la même époque, s'établissent à Sault-Marie les entreprises de Clergue, venues de Philadelphie. Avec l'ouverture des mines d'argent, d'or et de cuivre, la grande entreprise gagne le nord de l'Ontario et le nord-ouest du Québec. Elle atteint Rouyn en 1925 et Val-d'Or en 1936.

Full textAbstract:
BackgroundThe Occupational Disease Surveillance System (ODSS) was established in Ontario, Canada by linking a cohort of workers with data created from Workplace Safety and Insurance Board (WSIB) claims to administrative health databases. The aim of this study was to use ODSS to identify high-risk industry and occupation groups for lung cancer in Ontario.MethodsWorkers in the WSIB lost time claims database were linked to the Ontario Cancer Registry using subjects’ health insurance numbers, name, sex, birthdate and death date (if applicable). Several occupations and industries known to be at increased risk were outlined a priori to examine whether ODSS could replicate these associations. Age-adjusted, sex-stratified Cox proportional hazard models compared the risk of lung cancer within one industry/occupation versus all other groups in the cohort. Workers with a lung cancer diagnosis prior to cohort entry were excluded for analysis, leaving 2 187 762 workers for analysis.ResultsDuring the 1983 to 2014 follow-up, 34 661 workers in the cohort were diagnosed with lung cancer. Among expected high-risk industries, elevated risks were observed among workers in quarries/sand pits and construction industries for both sexes, and among males in metal mines, iron foundries, non-metallic mineral products industries and transportation industries. Excess risk was also observed among occupations in drilling/blasting, other mining/quarrying, mineral ore treating, excavating/grading/paving, truck driving, painting, bus driving and construction.ConclusionsThis current surveillance system identified several established high-risk groups for lung cancer and could be used for ongoing surveillance of occupational lung cancer in Ontario.

Natural resources are sources of much ecological instability. They are subjects of many types of research and led to the strengthening of measures. However, the exposure to hazards (water-air-soil pollution, radiation, degradation, etc.) due to such industries as mining continuous. This paper intends to show the dynamic relationships between production and time as part of the synergy of the whole extraction system over time. Given to sensitives issues known in the heart of mining operations, water is, therefore, the only environmental factor considered to lighten the research methodology. So, after the hypothesis, a temporal graphic with time and mining production level as explanatory and dependent variables is developed. Then, attention is given to the hypothesis validation used to highlight the joint result of the two variables. This is done by a literature review on environmental management risks tools existing, in-depth on the open pit mines with the simple linear regression analysis. The paired T-test Student result will help to clarify the potential of this statistical approach.

Full textAbstract:
In the Witwatersrand gold mining area, there have been recurring public complaints about dust dispersed from gold tailings storage facilities (TSFs) that traverse the landscape. Although weather aggravates the frequency and intensity of dust emission from TSFs in the study area, the rapid conversion of buffer areas around the dumps to residential land–use is exposing more people to dust hazards. This study assessed the effectiveness of Crown Mines Dust Monitoring forum in Johannesburg as an alternative environmental dispute resolution mechanism. Records of complaints from 1995 to 2010 that were made available through the forum were collated and analysed with the aid of descriptive statistics. Within the study period, complaints about mine pollution were more frequent between August and October, i.e. the dry months. More than 70% of the complaints were made by companies whose properties, operations and employees were affected by dust emission from the TSFs. While 52% of the complainants reported pollution problems for the first time within the study period, other cases were follow-up to previous complaints. Mining companies responded to 31% of the public’s grievances about dust pollution from their facilities within one week and another 12% in two weeks; response to the remaining complaints took much longer time. As part of mines’ response to public complaints, site visits were organised to indicted facilities, and pollution control measures and mitigation plan adopted at sites were also explained. Moreover, additional control measures were installed in critical circumstances to ameliorate dust pollution. Only a few of the complaints reported to the forum escalated to litigation or issuance of penalty by government agency. Although, the forum provided an avenue for resolution of environmental conflicts in a pragmatic and mutually beneficial manner, the right of the public to a clean environment is still not being realised fully.

Full textAbstract:
With regard to underground mining, methane is a gas that, on the one hand, poses a threat to the exploitation process and, on the other hand, creates an opportunity for economic development. As a result of coal exploitation, large amounts of coal enter the natural environment mainly through ventilation systems. Since methane is a greenhouse gas, its emission has a significant impact on global warming. Nevertheless, methane is also a high-energy gas that can be utilized as a very valuable energy resource. These different properties of methane prompted an analysis of both the current and the future states of methane emissions from coal seams, taking into account the possibilities of its use. For this reason, the following article presents the results of the study of methane emissions from Polish hard coal mines between 1993–2018 and their forecast until 2025. In order to predict methane emissions, research methodology was developed based on artificial neural networks and selected statistical methods. The multi-layer perceptron (MLP) network was used to make a prognostic model. The aim of the study was to develop a method to predict methane emissions and determine trends in terms of the amount of methane that may enter the natural environment in the coming years and the amount that can be used as a result of the methane drainage process. The methodology developed with the use of neural networks, the conducted research, and the findings constitute a new approach in the scope of both analysis and prediction of methane emissions from hard coal mines. The results obtained confirm that this methodology works well in mining practice and can also be successfully used in other industries to forecast greenhouse gas and other substance emissions.
