Abstract:

Coal mining policies and activities in addition to having a positive impact on state income, job creation and business, also have a negative impact on ecosystems and communities in the mining area. The study was conducted in two mining communities in South Kalimantan using an emic and etic approach to explore community resilience and food insecurity due to ecological changes and the impact of mining policies and activities. Coal mining policies and activities in South Kalimantan causes catastrophic floods, land damage, and crop failure on lowland rice fields that have an impact on potential food insecurity at the household and community level. The pattern of community resilience in the two communities is in the form of social movements as a form of social adaptation, and agricultural land recovery and changing agricultural commodities as a form of ecological adaptation. The process of community resilience in the two communities is at the level of recovery towards a stable community condition, not yet at the transformation stage. Community capability is the most influential factor on the degree of community resilience so that the handling of food insecurity based on community resilience needs to be done by developing strategies to increase community capability.

Abstract:

This open-pit mining activity has a very helpful environmental potential, soil chemistry, erosion and sedimentation. Change in land use from mining actively after mining requires land and energy closure to ensure that the land is safe for and returned. In accordance with the local spatial pattern in Muara Enim, South Sumatra, the transfer of post-mining land after the dismissal of mining operations will be used as a conservation area managed by the mining community. The concept is an environmental addressing plan to determine the sustainability of various aspects of community life, including local sustainability, food environment, awareness, biodiversity, and sustainability. This study aims to ensure community sustainability after mining operations. The methodology that is an interview with Experts. The results of this research indicate that community empowerment in mining area can use one of the community's natural resource management strategies to ensure social sustainability with land use as agroforestry and integrated agricultural industries.

Abstract:

Environmental problems have been caused by mining of ion-absorbed rare earth in South China, where chemical pollution in soil has been the most serious issues. There are rare earth mines in Longnan, Jiangxi Provence, South China as study object, where the investigation, sampling have been carried out and all samples were tested and analyzed. The results supported that key problems of polluted soil restoration in rare earth mining area are soil bad acidification and serious NH4+-N,NO3--N,NO2--N pollution. Limited factors of polluted soil restoration of rare earth mining area are presented. It is believe that adjusting pH values and denitrifying of the polluted soil in rare earth mining area and revegetation are feasible plan for soil restoration in rare earth mining area.

Abstract:

The coal bed methane resources distribution of Handan - Fengfeng Mining area has the features of "richness in the midland and north while poorness in the south, and richness in the east while poorness in the west. Through the analysis of the geological factors causing the above phenomena, we get that: the coal metamorphism and hydrogeological condition are the major controlling factors, the former controls the north and south difference of coal bed methane resources distribution from the two aspects covering gas-generated quantity and adsorption capacity, while the latter controls the east and west difference of coal bed methane resources distribution; syncline and good cap rock conditions are necessary conditions for coal bed methane enrichment, but not the reason for causing the difference of coal bed methane resources distribution.

Abstract:

Gold mining in south-east Sulawesi Bombana is one of the potential natural resources in Indonesia. But nowadays the condition is due to lack of responsibility of the mining business to conduct post-mining reclamation in Bombana area, even though the mining activity has been carrying out mining business license. Post-mining activities are very important and must be done by the mining company, because it can minimize the destruction of natural environment in the mining site. The purpose of this research is to find out the mining conditions in the Bombana area as well as arrangements related to post-mine reclamation in the Bombana area. This study was written using the normative from data obtained by library research. Then related to the implementation of post-mining reclamation in Bombana is currently not carried out maximally, it is due to the uncertainty of regulations related to the post-mine reclamation obligations and the sanctioned rules that will be applied in the future still depend on local government regulations but the implementation is still not able to work effectively. So the steps that need to be taken in this case to avoid damage to the environment surrounding the mining site is necessary cooperation between the Government, the mining business actors and the community using soil conservation technology such as post-mining reclamation, which is regulated in a clear, transparent, accountable legislation.

Abstract:

AbstractThe Department of the Environment and the Welsh Office jointly sponsored a South Wales Desk Study into the feasibility of producing thematic maps of the Mining subsidence risk for planners. A method was to be developed and tested for a 25 km2 Pilot Area centred on Ebbw Vale.The study was started by collecting geological and mining data for the Pilot Area and compiling this information on a map. It was then intended to prepare the mining subsidence map from this map by back analysing subsidence incidents to determine the hazardous areas. This simple approach could not be followed for two reasons. First, the record of mining was incomplete and it was therefore necessary to define ‘worked’ seams and areas from the total historical record and not only from the surviving mine plans. Secondly, insufficient subsidence incidents were discovered in the Pilot Area to carry out meaningful back analysis.The study was extended to collect all readily available records of subsidence incidents throughout the Coalfield. A total of 388 were traced, mainly dating from 1960. About threequarters were collapses through superficial materials and were either close to the outcrop or above mine entries, the remaining 25% propagated to the ground surface through rock. The upper limit of migration was typically 8 times the extracted height where the dip was shallow, incrasing to as much as 18 times for steep dips. Selected grout contracts and opencast mining sites were also examined to gain information on the present condition of old workings and to study the ‘reputations’ of the various seams for voids.The results of the coalfield study were applied to the Pilot Area to produce a 1:10 000 scale Development Advice Map, ‘Mining Subsidence for use by developers and planners’. The map is zoned to show areas where specialist advice is necessary to support a planning application and it also shows all mine entries traced by the desk study. The method of production is general for the South Wales Coalfield and further maps could be prepared, using the Coalfield Study, quickly and cheaply.

Abstract:

In the 140-odd years after the first diamond was found in South Africa in 1866, mining catapulted the country from a predominantly agrarian society into a modern industrial nation. For the biggest part of this period, mining drove and human development followed. This ?order of importance? was largely the result of the huge wealth and influence of the mining houses, the (perceived) importance of the sector for the development of the country, and the broader skewed power dynamics of colonial and apartheid rule. Over the last decade, national government enacted new legislation by which it attempted to ensure that mining is made more serviceable to the post-1994 objectives of (1) broad-based societal reconstruction; (2) shared and inclusive growth; and (3) regional and rural development. A key component of this new legislation has been a provision to ensure that mining companies make tangible contributions to regional and rural development and human settlement in ?mining areas?. Recent events, such as widespread strikes, the tragic loss of many lives, and continuing harsh living conditions, have raised, what has been a nagging question since the introduction of the new legislation, i.e.: Has the new legal framework (really) assisted in (1) ensuring that communities in mining areas enjoy a greater of the wealth created by the industry; (2) enhancing regional and rural development in mining areas; and (3) establishing a more symbiotic relationship between mining, regional and rural development planning and human development? In this paper, research in a mining area during the course of 2011 and 2012 is used to explore this question. Use is made of documented evidence and interviews with key role-players in the mining industry, municipal and provincial government, the private sector, traditional leadership structures and communities.

Abstract:

The coal and gas outburst is very serious in Yongshanqiao Mining Area of Jiangxi province, so it is of significance to research the characteristics of gas geology and their controlling factors. Based on the statistical analysis of gas data during coal exploration and coal mining, the regularity is revealed of the characteristics of gas geology in Yongshanqiao Mining Area. From east to west and from south to north, the relative gas emission rate and the absolute gas emission rate tend to increase, the frequency and intensity of coal and gas outbursts rise, the gas contents also tend to increase. The controlling factors of characteristics of gas geology in Yongshanqiao Mining Area are researched in this paper. The work reveals that: corresponding to characteristics of gas geology, the distribution characteristics of coal quality, the characteristics of geological structure and the lithology characteristics of the roof and the floor of the coal seams in Yongshanqiao Mining Area present regular changes, and are all favorable to gas generation and gas preservation. So, the characteristics of gas geology in Yongshanqiao Mining Area are the result of comprehensive effects by geological factors

Abstract:

Nickel mining activities in Obi Island, North Maluku Province use open-pit techniques, causing environmental problems. The purpose of this study was to evaluate the environmental conditions of the mining area and evaluate the obligations of the government of South Halmahera Regency in preparing and implementing environmental management instruments in accordance with UU No.32/2009. This research is a policy research to evaluate mining activities, using the Haas & Springer evaluation model. The results showed that mining activities in Obi Island, North Maluku Province caused a decrease in the quality of the environment, due to the Government of South Halmahera Regency which was not consistent in protecting and managing the environment, especially in the mining area, this can be seen from the absence of RTRW / RPMJD KLHS Documents, implementation of the UKL / UPL AMDAL that is not yet optimal, and there is no standard for B3 waste management and B3 waste dumping to the environmental media. Thus, the local Regency Government has not been able to implement environmental law policies properly, effectively and efficiently.

Abstract:

There are widespread mineralized systems, occurrences, deposits that occurred in the South Gobi, Mongolia, where many of them already undergone mining activity. However, not all of them have a pre-mining environmental assessment. The Shuteen area is one of these highly prospective areas for mining; due to the porphyry copper system observed, prospecting and exploration projects have been carried out since 1980. Numerous prospecting and exploration works have been done during 1997–2007 and suspended last decade because of economic and political reasons. The area is located in a Gobi-desert environment and wind plays a main role in the transport and mobility of the elements. This research was conducted to assess the environmental condition of the area, based on soil, dry river sediment, and drinking water geochemistry. We are expecting the area has a naturally high concentration of some heavy metals in soil, concerning the geology and mineralization. The results show that the heavy metal content in the soil does not exceed the permissible limit of the Mongolian National standard on soil quality. Whereas, the water samples contain F- above the permissible limit guided in the Mongolian National Standard on drinking water quality. The unusual chemical composition of the water is related to the soil composition characteristic of the Gobi region. They are characterized by low alkali, high salinity and mineral/water ratios are high. Environmental assessment surveys determine the characterization of an areal geochemical base prior the development of later exploration or mining project, might have affect it and establish the initial environmental status.

Abstract:

The ion-absorbed rare earth deposit occurred in the South of China is unique all over the world. Since the 1970s, rare earth in Longnan, South China has begun to be mined with leaching methods using oxalates and ammonium sulfate. Although this kind of methods is simple and economic, its presence in the environmental causes a growing environmental problems, especially changes in regional hydrochemical environment. In this paper typical ion-absorbed rare earth deposit——the Longnan rare earth mine, Jiangxi Provence, South China was selected as the study object, where the surface water and groundwater samples were collected. Analytic results show that the mining activities have affected the regional hydrochemical environment, which are expressed in the decreased pH（pH 3-4）, the enrichment of REE and heavy metal Pb in water with the maximum of 44760.1 μgL-1 and 1550 μgL-1 respectively, and the sulfate（214-1121 mgL-1）, ammonium（33.7-268 mgL-1） and nitrate ions（90-468 mgL-1） far beyond the background value. The impaction of the mining area surface hydrochemical environment is severest, then around the mining area, and the main rivers and groundwater in the study area have not been affected yet.

Abstract:

Illegal small-scale mining (galamsey) in South-Western Ghana has grown tremendously in the last decade and caused significant environmental degradation. Excessive cloud cover in the area has limited the use of optical remote sensing data to map and monitor the extent of these activities. This study investigated the use of annual time-series Sentinel-1 data to map and monitor illegal mining activities along major rivers in South-Western Ghana between 2015 and 2019. A change detection approach, based on three time-series features—minimum, mean, maximum—was used to compute a backscatter threshold value suitable to identify/detect mining-induced land cover changes in the study area. Compared to the mean and maximum, the minimum time-series feature (in both VH and VV polarization) was found to be more sensitive to changes in backscattering within the period of investigation. Our approach permitted the detection of new illegal mining areas on an annual basis. A backscatter threshold value of +1.65 dB was found suitable for detecting illegal mining activities in the study area. Application of this threshold revealed illegal mining area extents of 102 km2, 60 km2 and 33 km2 for periods 2015/2016–2016/2017, 2016/2017–2017/2018 and 2017/2018–2018/2019, respectively. The observed decreasing trend in new illegal mining areas suggests that efforts at stopping illegal mining yielded positive results in the period investigated. Despite the advantages of Synthetic Aperture Radar data in monitoring phenomena in cloud-prone areas, our analysis revealed that about 25% of the Sentinel-1 data, mostly acquired in March and October (beginning and end of rainy season respectively), were unusable due to atmospheric effects from high intensity rainfall events. Further investigation in other geographies and climatic regions is needed to ascertain the susceptibility of Sentinel-1 data to atmospheric conditions.

Abstract:

The Southern Waterberg in Limpopo Province is archaeologically rich, especially when it comes to evidence of pre-colonial mining and metal working. Geologically, the area hosts important mineral resources such as copper, tin and iron which were smelted by agriculturalists in the precolonial period. In this region however, tin seems to be the major attraction given that Rooiberg is still the only source of cassiterite in southern Africa to have provided evidence of mining before European colonization. This paper reports the results of archaeological and archaeometallurgical work which was carried out in order to reconstruct the technology of metalworking as well as the cultural interaction in the study area and beyond. The ceramic evidence shows that from the Eiland Phase (1000–1300 AD) onwards there was cross borrowing of characteristic decorative traits amongst extant groups that later on culminated in the creation of a new ceramic group known as Rooiberg. In terms of mining and metal working, XRF and SEM analyses, when coupled with optical microscopy, indicate the use of indigenous bloomery techniques that are widespread in pre-colonial southern Africa. Tin and bronze production was also represented and their production remains also pin down this metallurgy to particular sites and excludes the possibility of importing of finished tin and bronze objects into this area.

Abstract:

Biodiversity is the foundation of life-support systems on earth and underpins the delivery of ecosystem services (ES) important for human well-being. The loss of biodiversity worldwide, however, remains one of the most daunting challenges. Among the major causes of biodiversity loss is habitat loss due to transformation of land to agricultural, mining and urban areas. We applied the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) biodiversity modelling tool to assess the condition of habitats to support the delivery of ES in a biosphere reserve (BR) in South Africa. Results indicated that 72% of the surveyed habitats were of high quality to provide the necessary services. However, some of the habitats were found to be affected by threats as follows: low (0–20%) to moderate (20–32%) habitat loss was recorded in habitats adjacent to mining and plantation areas, and high (32–56%) to severe (56–95%) habitat loss was recorded in habitats in close proximity to urban and cultivated areas. At least 56% of the vegetation types found in the study area were threatened by transformation to agriculture, mining and urban areas. We strongly recommend that existing biodiversity policies and legislation should be enforced to avoid habitat loss and degradation.

Abstract:

South Africa has many artisanal and small-scale mining (ASM) activities that some are registered and others informal and illegal. This paper presents an overview of ASM operations in the vicinity of abandoned mine sites found in Giyani and Musina areas, Limpopo Provine of South Africa. It looks at the mining processes, environmental problems, and health and safety risks of ASM in the area. It also provideds a discussion of practical ways of dealing with the problems of artisanal and small-scale mining operations in a harmonized way with the rehabilitation of the abandoned mine sites. The exploitation of waste rock dumps for aggregate production in Musina demonstrated that formalized ASM activities can be the best alternative uses of the abandoned mine sites. However, artisanal gold mining around Giyani revealed the health and safety risks and environmental problems of these operations. The artisanal gold mining activities worsened the health and safety and the environmental problems of the abandoned mine sites. Therefore, this paper recommends that the efforts of coming up with strategies to formalize and regulate artisanal mining in South Africa be deepened for these activities to be accepteble as sustainable as post-mining land-uses in abandoned mines.

Abstract:

The last decade has seen a wide recognition of the chronic economic adjustment problems of the former coalfields of the UK. Arguably, the finest example of such an ex-mining area has been South Yorkshire. Common perceptions are of old mining communities that are lacking the key requisite characteristics to be sufficiently able to generate new and alternative forms of employment. That is, ex-coalfields are widely seen as possessing a poor set of the determining factors of economic competitiveness. This paper uses a study of manufacturing managers' perceptions of the determinants of competitiveness in the former mining area of South Yorkshire in order to shed new light on an established debate. It also takes an established methodology for assessing regional competitiveness and develops it into a more focused and valuable tool in feeding into the policy-making agenda. On the basis of the findings, some of the current policies aimed at the revitalisation of the economy of South Yorkshire's former coalfield are discussed, and a number of additions are suggested.

Abstract:

Its crucial to get information about lead (Pb) heavy metal pollution from mining and oil palm plantation on species density in mangrove ecosystem, to anticipate its impacts. This study aimed is to compare the types and densities of vegetation in mangrove ecosystems allegedly due to mining in Setarap village, Tanah Bumbu Regency and oil palm plantations in Kuala Tambangan Village, Tanah Laut Regency. We also analysis the condition of waters (TDS, pH and DO) and organic content in sediments to acquire data from the South Kalimantan mangrove ecosystems. The results showed there were four species of true mangroves (Avicennia alba, Acanthus ebracteatus, Nypa fruticans and Rhizophora apiculate) could live well in the environment affected by mining or oil palm plantations. The species density for trees was low (933 ind/ha) for mangroves affected by coal mines, while those affected by oil palm plantations had higher densities (1,067 ind/ha). pH value of waters in affected area by coal mining showed more acidic value (pH 5.76) especially at the back, while those by palm oil plantations are more acidic (pH 6) in the estuary. Organic matter content in sediments affected by coal mines was in the range of 0.61-6.59%, while those affected by oil palm plantations showed higher values (0.12-2.19%). Lead heavy metal content (Pb) in waters affected by coal mines was 0.031-0.056 mg/L, while the area affected by oil palm plantations was of higher value (0.110-0.128 mg/L). Lead (Pb) levels in sediments indicate higher values than waters, which reach 3.512-6.046 mg/Kg (affected by coal mines), and in areas affected by oil palm plantations reaching 6.658-6.66 mg/Kg. The general conclusion is that vegetation densities in areas affected by coal mines are lower than oil palm plantations. The level of lead (Pb) pollution in the sediments is higher than in the waters.

Abstract:

Mining is a major economic activity in many developing countries. In South Africa, gold mining has played a significant role in the development and sustenance of the country's economy, with both positive and negative consequences. In gold mining areas, tailings dams and mine dumps are significant sources of ambient dust, known to be a nuisance, and health risk, to communities living near them and who must find appropriate coping mechanisms to protect themselves. A qualitative study based on five focus groups with sixty-two participants of different ages and sex was carried out in the Witwatersrand mining district of South Africa. All focus groups agreed that they had noticed dust in the air where they live, stating that the dust came largely from mine dumps but also from other sources. They agreed that the dust causes, among others, health problems, and both short-term and long-term coping mechanisms for protecting themselves against excess dust were mentioned yet considered inadequate, i.e. closing windows and doors, watering their yards, paving their yards and planting trees. Little support from government, mines and other organisations was identified as an important perceived barrier to resolving the dust problem. Means for communication of communities' perceptions of the impacts, risks and possible mitigation / adaption measures associated with dust need to be created and supported in a formal risk management plan.

Abstract:

Florida has a long history of phosphate-mining, but less is known about how mining affects nutrient exports to coastal waters. Here, we investigated the transport of inorganic and organic forms of nitrogen (N) and phosphorus (P) over 23 sampling events during a wet season (June–September) in primary tributaries and mainstem of Alafia River that drains into the Tampa Bay Estuary. Results showed that a tributary draining the largest phosphate-mining area (South Prong) had less flashy peaks, and nutrients were more evenly exported relative to an adjacent tributary (North Prong), highlighting the effectiveness of the mining reclamation on stream hydrology. Tributaries draining > 10% phosphate-mining area had significantly higher specific conductance (SC), pH, dissolved reactive P (DRP), and total P (TP) than tributaries without phosphate-mining. Further, mean SC, pH, and particulate reactive P were positively correlated with the percent phosphate-mining area. As phosphate-mining occurred in the upper part of the watershed, the SC, pH, DRP, and TP concentrations increased downstream along the mainstem. For example, the upper watershed contributed 91% of TP compared to 59% water discharge to the Alafia River. In contrast to P, the highest concentrations of total N (TN), especially nitrate + nitrite (NOx–N) occurred in agricultural tributaries, where the mean NOx–N was positively correlated with the percent agricultural land. Dissolved organic N was dominant in all streamwaters and showed minor variability across sites. As a result of N depletion and P enrichment, the phosphate-mining tributaries had significantly lower molar ratios of TN:TP and NOx–N:DRP than other tributaries. Bi-weekly monitoring data showed consistent increases in SC and DRP and a decrease in NOx–N at the South Prong tributary (highest phosphate-mining area) throughout the wet season, and different responses of dissolved inorganic nutrients (negative) and particulate nutrients (positive) to water discharge. We conclude that (1) watersheds with active and reclaimed phosphate-mining and agriculture lands are important sources of streamwater P and N, respectively, and (2) elevated P inputs from the phosphate-mining areas altered the N:P ratios in streamwaters of the Alafia River.

Abstract:

Coal mining activities may cause a series of environmental and socio-economic issues in communities around the mining area. Mining can become an obstacle to environmental sustainability and a major hidden danger to the security of the local ecology. Therefore, the coal mining industry should follow some specific principles and factors in achieving sustainable development. These factors include geological conditions, land use, mining technology, environmental sustainability policies and government regulations, socio-economic factors, as well as sustainability optimization for post-mining land use. Resources of the remains of the coal which is defined as the last remaining condition of the resources and reserves of coal when the coal companies have already completed the life of the mine or the expiration of the licensing contract (in accordance with government permission). This research uses approch of knowledge-driven GIS based methods mainly Analytical Hierarchy Process (AHP) and Fuzzy logic for utilizing coal remaining resources and post-mining land use planning. The mining area selected for this study belongs to a PKP2B (Work Agreement for Coal Mining) company named Adaro Indonesia (PT Adaro). The result shows that geologically the existing formation is dominated by Coal Bearing Formation (Warukin Formation) which allows the presence of remains coal resource potential after the lifetime of mine, and the suitability of rubber plantation for the optimization of land use in all mining sites and also in some disposal places in conservation areas and protected forests.

This study aims to obtain information about the causes of the rise of sand mining on the coast of Batauga, South Buton Regency. This research uses a qualitative research design with a descriptive analysis method by describing it as it is about the reality obtained in the field. Data collection is done through observation and interview techniques. The results showed that the cause of the rise of sand mining in the Batauga District was caused by several factors, namely: 1). Low level of education and economic factors, sand mining activities do not require special expertise and can make money in a short time unlike farming or fishing, 2.) Lack of understanding and awareness, the community is relatively unaware of and aware of the long-term risks of mining sand, the conviction of the miners if the beach sand will never run out, and the belief that the coastal area is claimed the land as private property so that it has become the community's right to process it 3). Lack of socialization and no penalty (sanctions) for miners, 4). The existence of omission and granting of mining licenses from the government (legality) by withdrawing fees from sand mining.

According to the basic characteristics of geological environment in Pingyao mining area, we analyzed the relationship between coal mining and the ground fissure disasters in recent years. The result shows that the mine goaf is the essential factor for the formation of ground fissure, and the precipitation and groundwater drainage accelerates its development. Based on a systematic analysis of classification of goaf as well as the distribution characteristics and the formation mechanism of ground fissure, we found that the ground fissure in this area is non-tectonic, and thus proposed corresponding prevention and control measures. Research results would provide basis for the improvement of local environmental conditions and the control of geological disasters.

Abstract:

Mining has long been at the center of the South African economy and has contributed to significant developments within the country. However, despite the large economic impact, surface water pollution due to mining is prevalent in most of the country's water catchments. Surface water in many areas of the central Roodepoort area in Johannesburg, South Africa, has also been impacted primarily by mining activities. The surface water quality for the Bosmontspruit, Russell's Stream, and the New Canada Dam was assessed in this study from October 2010 to March 2011. Physicochemical and biological characteristics of the water were determined for eight monitoring points, and the results obtained were compared with the in-stream water quality guidelines for the Klip River catchment and the South African Water Quality Guidelines. A trend noticed throughout the sampling period was the noncompliance to the set target water quality ranges (TWQRs) in the levels of total dissolved solids (TDS) and dissolved oxygen (DO). The results indicate that concentrations of iron, aluminum, nickel, manganese, and potassium were above the permissible limits across the Bosmontspruit and Russell's Stream. Excessive fecal coliforms and ammonium pollution were also detected in the Bosmontspruit. Additionally, during the monitoring period, it was noted that the water was being utilized for domestic purposes, and may pose health hazards due to poor water quality.

Full text

Abstract:

Considering the negative impact of mining on ecosystems in mining areas, the South African government legislated the Mineral and Petroleum Resources Development Act (No. 28 of 2002), to compel mining companies to restore the land affected by mining. Several studies have used remotely sensed data to observe the status and dynamics of surface mines. Advances in remote sensing along the cloud-based Google Earth Engine (GEE) now promise an enhanced observation strategy for improved monitoring of mine environments. Despite these advances, land rehabilitation at Richards Bay Minerals (RBM) is mainly restricted to field-based approaches which are unable to reveal seamless patterns of disturbance and restoration. Here, we illustrate the value of the trajectory-based LandTrendr algorithm in conjunction with GEE for mine rehabilitation studies. Our automated method produced disturbance and recovery patterns (1984–2018) over the RBM site. The study revealed that RBM has progressively been mining different portions of the mineral-rich coastal area after which restoration was undertaken. The duration of mining over each site ranged from 2 to 6 years. The LandTrendr outputs correspond with independent reference datasets that were classified with an overall accuracy of 99%; it captures mine-induced disturbance efficiently and offers a practical tool for mine restoration management.

Case overview The case focuses on the dilemma that Phiwokuhle Mhlangu in Mpumalanga, South Africa, faced when his company’s board had not signed off on capital expenditure to improve his colliery’s clean coal technology initiatives. He had to influence his colleagues’ mindsets to adapt to changes in the environment. The case highlights the global coal landscape and South African mining industry’s challenges in terms of infrastructure and strained labour relations, as well as the focus of the South African Government to enhance alternative energy resources. Although a clear business case for investment in clean coal technologies was evident, Mhlangu could still not persuade his colleagues to support these initiatives. A different approach was required […] Expected learning outcomes The learning objectives in this case are: gaining insight into the dilemmas of sustainability in coal mining by exploring various interest groups in difficult sustainability situations and enhancing understanding of getting a buy-in from various stakeholders when leading change in the coal-mining sector. Supplementary materials A teaching plan and particular teaching methodologies is included. The two learning outcomes are posed as questions for groups to discuss and model answers are provided and to relevant literature. Subject code CSS 7: Management Science

Abstract:

Background and aims – The rapid expansion of human activities in South Cameroon, particularly mining in mountainous areas, threatens this region’s exceptional biodiversity. To comprehend the effects of land-use change on plant diversity and identify conservation priorities, we aim at providing a first comprehensive plant checklist of the Ngovayang Massif, focusing on the two richest plant families, Orchidaceae and Rubiaceae.Location – The Ngovayang Massif Area (NMA) is located in the South Region of Cameroon. It is covered by lowland and submontane rainforest (100 to 1110 m elevation).Methods – We compiled a dataset of 6116 georeferenced herbarium specimens, of which 2787 belong to Rubiaceae and Orchidaceae. We used rarefaction methods to explore sampling and diversity patterns, and investigated the altitudinal distribution of rare and/or threatened taxa.Key results – The NMA, which houses about 1500 vascular plant taxa, is the richest documented area for Rubiaceae in Atlantic Central Africa (ACA) and the fifth for Orchidaceae, with respectively 281 and 111 taxa. Among these taxa, 178 (45%) are endemic to ACA and 67 (17%) are considered globally threatened according to IUCN categories and criteria. We show that higher elevation areas (> 750 m), which are also the main areas targeted for mining, are the richest in endangered and/or rare species. Three new records for Cameroon are reported here.Conclusion – The NMA represents an Important Plant Area of Cameroon as confirmed by its exceptional plant diversity (> 20% of the total Flora of Cameroon), by the concentration of many threatened and/or restricted range species (10 taxa are strict endemics of the massif) as well as by the threat on rare habitats (i.e. the submontane vegetation above ~750 m elevation). A management plan involving in situ and ex situ conservation actions is urgently needed to reduce the potential threats of future mining activities.

Opencast mining of large-area lignite deposits impacts the environment, and the health and life of people living in the vicinity of the conducted mining activity. Therefore, the attempt was made to develop a methodology for identification of environmental and social changes in the Bogatynia municipality (south-western Poland), resulting from functioning of Turow lignite mine within its area. During the study of changes occurring over the years, the development of mining pit was noticed, as well as the transformations of this area and impact of the mining plant on the selected elements of environment and surrounding areas. Analogue and digital data were used for the preparation of cartographic compilations, the usefulness of which was analyzed in accordance with the guidelines contained in the standard [1]. The conducted cartographic studies allowed to learn the history of the mine together with identification of changes taking place in the municipality Bogatynia. The obtained results show the form and condition of the objects in the analyzed year, allowing for the interpretation of changes that occurred in the surrounding areas of the Turow mine. Due to the conducted activity of the mine and Turow power plant, both negative and positive aspects were noted in connection with the carrying out of mining activity in the Bogatynia municipality.

Abstract:

Due to the different in-situ stress level, mining stress state, and surrounding rock properties of steeply inclined deep coal mining, the mutation mechanism of underground engineering rock mass is complex. This paper studies the cause and control of mining disaster of steeply inclined deep coal resources in Wudong coal mine. The results show that the structural field is the key of multifield analysis, and particularly a large area of suspended roof is easy to expand energy and induce dynamic hazards. By means of borehole television- (BT-) transient electromagnetic (TEM) detection, it is found that there are hidden dangers of roof safety and suspected water hazards in Wudong coal mine, and the roof above the detection area (+575 m south roadway to 2250–2600 m) is in a suspended state; there is a suspected water-rich area in the range of 2320–2340 m and 2390–2400 m, and the lowest vertical height is +613.8–+615.5 m. Exploring and releasing the water in the aquifer effectively reduced the water pressure; in +575 m south roadway, +587 m measure roadway, and blasting chamber, the suspended roof blasting holes are constructed. Microseism- (MS-) TEM monitoring shows that the apparent resistivity fluctuates significantly, the microseismic energy and events have been significantly reduced, and it is maintained at a low level for two consecutive weeks, confirming the effectiveness of the stable release of the high-stress roof in the +575 m near stope area; at the same time, the safeguard measures for long-term roof dynamic monitoring are constructed.

In order to estimate the present exposure risk of Cadmium dietary intake by inhabitants in a W-Mo mining area, South China, a dietary investigation was conducted with stratified cluster random sampling method. According to the result, a total of 7 food groups, including rice, vegetable, meat, chicken and egg, were sampled from contaminated areas using the total dietary study method. Rice consumption took up 81.5% of food consumption. Cadmium content in 45.8% of 306 rice samples, 11.1% of 252 vegetable samples, and 4.8% of 21 chicken samples exceeded the limit. Risks of cadmium in study area are between 1.0E-06 and 1.0E-03, which is acceptable but need further attention to reduce them. Rice products were the highest contribution, which took up about 80.1%. The results showed that Cadmium intake was much higher around W-Mo ore deposit than that in reference area.

Abstract:

Abstract The Helgoland Mud Area (HMA) in the German Bight, covering an area of approximately 500 km2, is one of a few depocentres for finer sediments in the North Sea. Radiocarbon and 210Pb analyses revealed continuous sedimentation over the last several centuries. Zinc (Zn) and lead (Pb) contents in the sediments show a distinct increase towards the youngest most sediments with the thickness of the heavy metal enriched sediments ranging from 15 to 103 cm. Stratigraphic data indicate that the onset of heavy metal enrichment is diachronous progressing north-westward over the depocentre, paralleled by a decrease in the thickness of the enriched layer. Beginning already during medieval times, the enhanced input of Zn and Pb seemingly is related to silver and zinc mining in the Harz Mountains and the Erzgebirge, well-known mining areas since the Bronze Age. Both regions are directly connected to the HMA by the Elbe and Weser rivers. Zn and Pb enrichment began in the south-eastern HMA and progressed subsequently with an average of 10 m per year north-westward, most likely triggered by variations in river discharge and by the hydrodynamic setting. Quantitative assessments of the Zn and Pb content in the sediments suggest that since the onset of enhanced Zn and Pb deposition, the anthropic Zn and Pb input in the HMA amounts to ~ 12,000 t and ~ 4000 t, respectively.

Abstract Mining business actors have an obligation to maintain the sustainability of the surrounding environment, both in the physical and the social environment. Coal mining extraction activities are closely related to the exploration and exploitation of natural resources. This activity is in contact with the interests of the surrounding community, in particular with the negative impact caused. Mining companies in Indonesia are bound by the Mineral and Coal Mining Act no. 4 of 2009 to carry out community development and empowerment. Under the law, the companies are required to implement Corporate Social Responsibility (CSR). Through the implementation of CSR is expected the company can provide a positive change for the survival of communities around the mining area. PT BARA is one of mining companies that had been implementing CSR since 1983. As a state-owned company PT. BARA has various binding regulations in the implementation of CSR. The regulation comes from the central government as well as the local government in which PT. BARA does its mining business. Every year PT BARA releases an enormous amount of CSR funds, but the surrounding community is still in a state of poverty. It turns out that the problem does not stop on poverty at all. The community becomes very dependent on the company's assistance. The purpose of the CSR program is to develop and empower the community has not been able to achieve the goal. This dependence is caused by various reasons such as CSR policies of companies as well as government and CSR implementation on society.

Abstract:

The sources of tin in the ancient Near East have been a long-standing puzzle. Anatolia is a key area, for it has copper in vast quantities, and silver. Since no substantial or workable deposits of tin seemed to exist in Turkey, an external source for tin bronzes in Anatolia has seemed necessary. The new finds reported here change that picture, as they reveal a major source of the metal in the Taurus mountains, on the south coast of Anatolia.
