Abstract:

   PT. Bumi Resources Tbk. has absolute controlling shares of its subsidiaries (subsidiaries), so PT. Bumi Resources Tbk. can control, coordinate and be absolutely responsible for the operational activities of its subsidiaries. To expand its network, PT. Bumi Resources Tbk. formed a subholding company, PT. Bumi Resources Mineral Tbk. (BRM). BRM focuses on being a holding company that manages several subsidiaries engaged in the non-coal business. The establishment of this subholding cannot be separated from the expansion carried out by PT. Bumi Resources Tbk. which has acquired several non-coal mineral companies, including Calipso Investment Pte Ltd (99%), International Minerals Company, LCC (100%), Lemington Investments Pte.Ltd (99%), PT. Citra Palu Minerals (96.97%), PT. Dairi Prima Mineral (80%), PT. Multi Capital (99%), and PT. Sarkea Prima Minerals (20%). These companies subsequently become subsidiaries and / or affiliates of PT. Bumi Resources Mineral Tbk.

Abstract:

A significant contribution to the economic growth of a nation comes from the mineral industries. Therefore, the concentration of metallic or nonmetallic minerals in different regions of Earth’s crust is important to determine. The present paper studies the grade and thickness estimation of iron and coal deposits, respectively, by applying two-dimensional cellular automata (CAs). Krigging is a popular method for the estimation of mineral resources. However, krigging results in complex mathematical calculations if the number of sample points increases. Here, each cell of the cellular automaton (CA) is represented as a block. Using CAs, the grade values and thickness are estimated in a simpler and faster way. Two-dimensional CAs are used in this paper where the local rule is the ordinary krigging estimator function using the spherical variogram model. The total weight of iron as well as coal is calculated using the CA-based technique. A comparative analysis between the estimated weight of minerals and the actual extracted mineral is also given.

Abstract:

The diversity of coal measure determines the occurrence state and spatial distribution complexity of mineral resources. Abundant resources have become an important part of geological resources and have attracted more and more attention. Coal measure and their overlying and underlying strata often coexist with various mineral resource types, and there is a certain relationship between their genesis and occurrence. In order to further enrich the theory of comprehensive exploration and coordinated development of multi-mineral resources, this paper takes the Huanghebei Coalfield as an example to systematically study the genesis mechanism and occurrence law of coal seam, coalbed methane, and coal-measure shale gas in Late Paleozoic and rich iron ore in Ordovician limestone underlie coal measure. The research is that: 1) The Late Paleozoic Carboniferous-Permian Marine facies, terrestrial facies, and transitional facies all developed in the coal-bearing area in the Huanghebei Coalfield, and the coal seams and mud shales developed well in Shanxi Formation and Taiyuan Formation. 2) Yanshanian magmatic intruded into Ordovician limestone. Contact metasomatism occurred between the ore-bearing hydrothermal fluids and the surrounding rocks, which led to skarn formation. The magnetite mineralization occurred in the metasomatism alteration process, and finally, the contact metasomatic iron deposit was formed; 3) Yanshanian magma intrusion has a significant impact on the generation of coal from coalbed methane and shale gas in the coal measures of Late Paleozoic. The magma carries a lot of heat by baking the coal seam and overlying shale, which is reflected explicitly in the increasing metamorphism degree of coal. Under the action of high temperature, the secondary gas of coal seam and coalbed methane increase sharply. The maturity and thermal evolution of organic matter in shale beds increased, and the shale gas entered a favorable range. The intrusion of magma greatly enhances the thermal evolution of organic matter in coal and shale, forming a variety of coals and promoting the generation and accumulation of coalbed methane and shale gas. At the same time, Mesozoic magmatic intrusion also controlled the formation of rich iron ores. According to the characteristics of mineral development and distribution in the study area, a multi-mineral development and distribution model of “coal - coalbed methane - shale gas - rich iron ore” coexists in the Huanghebei Coalfield, which is referred to as the “Huanghebei model”.

Abstract:

Prospects for increasing the mineral resource base of the Lvov-Volyn coal basin are associated with the development of new areas and large horizons. One of the possible directions is the construction and operation of mining complexes within the fields of the South-Western coal-bearing region. In terms of the grade composition at the Tyaglov deposits, gas, gaseous fatty and fatty coals prevail. It has been proven that gas coal is suitable for coking. At the Lyubelya deposit, there are fatty, coke fatty and coke. Coking coal accounts for almost half of the deposit's reserves. The reserves and resources of coal in the region are estimated at more than 2 billion tons, which are twice the residual reserves of the industrial part of the basin. It is of great importance to study the layers v03, v04, v2, v4, v43, v54, v56, v6 and n06, related to the lower coal-bearing subformation of the basin. Prospects for the integrated development of ABL resources associated with the gas content of the coal-bearing strata. Deposits of the Lvov-Volyn basin can, to a certain extent, be considered as complex gas-coal. The Southwestern coal-bearing region and deep horizons of the basin are especially promising.

Abstract:

The management of mineral and coal resources is affected by the shift in the paradigm of regional government administration, which now emphasizes aspects of regional autonomy. Law Number 23, 2014 concerning Regional Government, which genuinely adheres to the maxim of maximal regional autonomy, appears to be incompatible with Law Number 3, 2020 concerning the revision of Law Number 4, 2009 on Mineral and Coal Mining. In practice, this results in a variety of interpretations of the nature and significance of regional autonomy, which ultimately has repercussions for the management of mineral and coal resources. This research aims to investigate the significance and nature of regional autonomy in connection to the management of mineral and coal resources. This is doctrinal legal research and a philosophical approach is applied based on legal principles. The findings are the fundamental principles of managing mineral and coal resources in the future era of regional autonomy focuses on returning to the principle of being a state, which means that the use of mineral and coal resources must be in accordance with the ideals of the state outlined in paragraph 4 of the Preamble of the 1945 Constitution, aspects of environmental harmonization and spatial alignment and the application of the principle of proportionality in regulating government and local government authorities.

Abstract:

Ordos is the most abundant coal resource city in Inner Mongolia. Its coal resources account for one half of Inner Mongolia's coal resources and one sixth of China's total coal reserves. Abundant coal resources have laid the foundation for Ordos become today’s resource-based city. In 2003, Inner Mongolia issued “the guiding opinions on accelerating the development of key coal enterprises” (hereinafter referred to as “policy”), supporting the development of coal enterprises and providing policy conditions for the rapid economic development of Ordos. However, with the rapid development of economy, the rural-urban income disparity is also getting bigger in Ordos. Based on panel data from 1999 to 2012 and use the DID analysis of “quasi-natural experiment”, the paper finds that the policy has increased the rural-urban income disparity. The policy increases the rural-urban income disparity by promoting GDP growth. Therefore, the role of the policy system in the economic development of a region cannot be ignored. The government supports the development of local resource-based industries and also increase support for the development of upstream and downstream industries. Under the guidance of policy, the mineral resources income should be transformed reasonably. Government should invest the proceeds of mineral resources in material capital and human capital. Government also should invest the proceeds of mineral resources in external industries and projects that require large initial capital or long construction cycles, such as those essential infrastructure sectors: education, health, transportation and energy. In this way, the integration of urban and rural development will be realized and the rural-urban income disparity will be reduced.

Abstract:

With the issuance of Law no. Law No. 3 of 2020 replaces Law No. 4 of 2009 concerning Mineral and Coal Mining. It is hoped that it will position the Indonesian state as the sovereign party over its natural resources. Therefore, it is necessary to formulate the problem, namely how to study the legal politics of Law No. 3 of 2020 concerning Mineral Mining. And Coal towards the obligation to process and refine mining products domestically. The research method is normative with several approaches, namely the Conceptual Approach and the Statute Approach. From the results of the author's research, it was found that the government considers it necessary to increase the added value of minerals through domestic mineral resource processing and refining activities, as intended in Article 103 and Article 170 of Law Number 3 of 2020 concerning Mineral and Coal Mining, so the government then promulgate Government Regulation (PP) No. 96 of 2021 which is an amendment to PP No. 1 of 2014 concerning Implementation of Mineral and Coal Mining Business Activities. One of the important regulations in this PP is the obligation to carry out 100% mineral refining domestically so that there will be no more exports of raw minerals by mining companies. The aim of banning exports of raw minerals is to increase fiscal added value while creating jobs. Because mining companies are required to build processing plants or smelters in the country. In this way, new job opportunities will be opened for the Indonesian people

Abstract:

The analysis of the state and prospects for the development of the mineral resource base of the Vorkuta region of the Komi Republic, belonging to the Arctic zone, was carried out. It is shown that the coking coal deposits of the Pechora basin, the development of which is the basis for the existence of the city of Vorkuta, were and still are the most impor-tant ones. The reserves of coking coal are significant, however, the supply of them to operating mining enterprises is becoming more and more limited. To maintain and develop coal mining, it is necessary to build new mines. Along with the coal deposits, the Vorkuta region is of great interest in relation to other minerals. In the Kosyu-Rogovsk and Koro-taikha depressions, there are potential oil and gas-bearing structures, on the western slope of the Polar Urals – barite deposits, gold, chromium and copper occurrences, deserving further geological study and prospecting works. For a more complete disclosure and development of the mineral resource potential of the Vorkuta region, the extension of transport infrastructure is of great importance. The implementation of plans for the construction of railways, access to the Northern Sea Route, can contribute, in particular, to increasing the volume of coal production and wider supplies of coal using sea transport, and raising the investment attractiveness of the Arctic territories.

Abstract:

The overlapping mineral resources are always occupied by the various buildings and cannot be exploited anymore, so to determine their boundaries correctly is an important task for both local government and constructers. Based on “regulations about exploiting overlapping coal and keeping coal pillar for buildings, waters, railways and major tunnels”, the software is developed to calculate the overlapping mineral resources. Four main design steps about the software are illustrated, the main dialogue box of the software is introduced, which is composed of three part boxes. In the end Chaochuan industry square is selected as an example, variables are calculated by the software, and the protected boundaries are drawn in MapGis.

Abstract:

Research objective is to substantiate the relevance of mining transition to eco-friendly technologies of subsurface use. Methods of research include analyzing theory and practice of environmental technologies application and carrying out a multifactor experiment. Results. An efficiency criterion for mineral resources extraction technologies is proposed that involves reducing the effect made by the by-products of mining and processing enterprises on the state of the environment. The problem is considered of minimizing the environmental damage from storing silt coal in dumps and storages by utilizing their components. The mechanism of environmental pollution has been formulated. Aspects of metal recovery from beneficiation tailings in a disintegrator mill are investigated. A reduced threat to living matter is predicted by implementing the concept of radical waste-free processing of substandard mineral raw materials. The need to improve the processes of crushing, fine grinding, and classification of minerals in mills to reduce the waste of coal production, harmful to the environment, is noted. Conclusions and scope of the results. Deteriorated conditions of mineral deposits development raise the risk of man-made impact on the environment in coal-mining regions. The global human population grows resulting in increased resources production to respond to resource needs. The growing threat to living matter can be reduced by radical measures, the non-waste processing of substandard mineral raw materials being the priority. The research results can be helpful in the development of deposits of solid metal-containing technologically exposed ores

Abstract:

In May 1981, at the South Wales Area NUM annual conference, Area president Emlyn Williams addressed the delegates and told them that the south Wales miners 'are associated in people's minds with resistance and struggles ... There is no doubt in my mind that miners have an historical mission to lead in class struggles'.1 This statement expressed the conscious self-image of the South Wales Area and was also a reaffirmation of an important historical trend. During the twentieth century the miners were generally considered to be amongst the most militant sections of the British labour movement, with South Wales very much in the forefront of this. This thesis examines both how and why the south Wales miners held this prominent 'vanguard' role. My research explores the history of the south Wales miners between 1964 and 1985, examining the interrelationship of coal, community and politics through the prism of their Union. The period covers the concerted run-down of the coal industry under the Wilson government, the growth of miners' resistance and the brief prospect of a secure future for them, through to eventual NUM defeat in 1985. In this socio- political history, the emphasis is on the dynamics of the relations between colliery lodges, the South Wales Area and the national NUM, the response of the Area to industrial and political developments, and also the impact of this upon its relationship with the wider labour movement. In many respects however, labour history is not currently 'fashionable'. The decline of the densely-unionised heavy industries, together with the global hegemony of neo-liberalism, has led many to believe that this subject is no longer relevant - even though the working class has not disappeared just because more people in Britain now work in call centres and supermarkets than in collieries or steelworks. Nevertheless, as Mcllroy and Campbell point out, '[t]he [current] debility of labour studies ... have to be related to the defeats and the consequent sense of demoralisation the labour movement has suffered from, as well as state policies and academic responses to them'.

Abstract:

Run-of-mine (ROM) coal sampling is one of the most important factors in determining the disposition of ROM coal for an overall emission control strategy. Determination of the amount of sample, or still better, the frequency of ROM coal sampling is thus essential to the analysis of overall emission control strategies. A simulation model of a portion of the Upper Freeport coal seam in western Pennsylvania was developed employing conditional simulation. On the simulated deposit, different mining methods were simulated to generate ROM coal data. ROM coal data was statistically analyzed to determine the sampling frequency. Two schemes were suggested: (1) the use of geostatistical techniques if there is spatial correlation in ROM coal quality, and (2) the use of classical statistics if the spatial correlation in ROM coal quality is not present. Conditions under which spatial correlation in ROM coal quality can be expected are also examined. To link the ROM coal and coals from other sources to coal stockpiles and subsequently to solve coal blending problems, where varying qualities of stockpiled coals are normally used, an interactive computer program was developed. Simple file-handling, for stockpiling problems, and multi-objective goal programming technique, for blending problems, provided their solutions. The computer program was made suitable for use on both minicomputer and microcomputer. Menu-driven and interactive capabilities give this program a high level of flexibility that is needed to analyze and solve stockpiling and blending problems at the power plant.

Abstract:

Scholarly and public analyses of state-community conflict in resource-rich communities, especially in Nigeria, often portray the compensational practices of the state and extractive enterprises as unjust and unsustainable. According to this view, at least three issues foreground the “unjustness”, namely: a) Inadequate compensation of land owners when land is expropriated or degraded in the process of natural resource exploration and production; b) inadequate periodic rents paid by extractive firms to land owners; and c) lack of, or inadequate socio-economic infrastructure in the host communities of extractive operations. Most analysts have therefore argued for a revamp of the compensation system and have presented the inadequacy of compensation as the underlying cause of conflict in Nigeria‟s mining communities (see Frynas, 2000b:208; Okoji, 2002:205). This thesis subjects the compensation discourse to a closer examination, especially against the backdrop of underdevelopment, pervasive poverty, environmental damage and continuing corporate-community conflict in Nigeria‟s resource-rich rural communities. The main argument is that, because of some of its underlying neoliberal assumptions, much of the compensation discourse is flawed – which is why the discourse obscures the true character of state-community and corporate-community conflict. This more so, because the discourse relies mainly on post-colonial (that is, post-1960) experiences and contemporary advocacy literature, ignores the interplay between history and contemporary developments in state-community relations, and treats compensation as an independent variable. Drawing on the concept of collective memory, and utilising historical, ethnographic and survey data from two of Nigeria‟s oldest petroleum and coal-mining communities, the thesis examines how the evolution of the Nigerian state and collective memory about aspects of that evolution have shaped state-community relations in the extractive sector. It situates state- iii community resource-related conflict within the wider socio-historical matrix of state and community contestations for ecological and natural resource sovereignty. The key finding of the thesis is that within the context of socio-ecological rights, compensation demands by local communities are textured. In the case of the communities selected for the study, such demands are often made outside, rather than within, local ethnographic ideas of “justness” and “fairness”. Hence, land-related grievances associated with natural resource extraction persist, regardless of whether or not local demands for compensation are “adequately” met by the state and extractive corporations. The thesis enriches and extends our understanding of natural resource conflict by privileging both the sociological and historical contexts of the conflict and raising questions about the dominance the state enjoys over local communities and indigenous ecological spaces.

Abstract:

Der Beitrag beschreibt die Voraussetzungen des gelungenen Strukturwandels mit der Bündelung der Potentiale von Bodenschätzen, Geographie, Wirtschaft und Bevölkerung. Das Ruhrrevier in seiner heutigen Form ist im besonderen Maße Ausdruck der montanindustriellen Entwicklung. Diese wiederum hängt maßgeblich von der Ausbildung der Steinkohlenlagerstätte ab. So sind es die geologischen Schichten der Region, die diese nachhaltig gestaltet haben. Die Steinkohlenlagerstätte des Ruhrreviers entwickelte sich bereits vor über 300 Mio. Jahren unter subtropischen Bedingungen. Meeresnahe Ablagerungen sind Ursprung des „schwarzen Goldes“, der Steinkohle zwischen Ruhr und Lippe. Eine wechselvolle Geschichte führt über Gebirgsbildungen, Fort- und Rückschreitung der Küstenlinie sowie eiszeitlicher und fluviatiler Sedimentationen zur Gestaltung von Geologie und Morphologie im Ruhrrevier. Die heutige Raumstruktur des Ruhrgebiets entstand somit aus der Geomorphologie des Karbons mit den sich herausgebildeten Flüssen Ruhr, Emscher und Lippe und den sich daran orientierenden mittelalterlichen Städten und Siedlungen. Mit den Auswirkungen der industriellen Revolution auf Basis Kohle, Eisen und Stahl veränderte sich die Region von einem landwirtschaftlich geprägten Raum hin zum heutigen Ballungsraum mit über 5 Millionen Einwohnern. Von den ehemals über 400 Zechen im Ruhrrevier existierten im Jahr 2015 noch zwei fördernde Bergwerke. Das Bergwerk Auguste Victoria wurde Ende 2015 eingestellt, das Bergwerk Prosper Haniel wird Ende 2018 die Förderung einstellen. Damit endet der subventionierte Steinkohlebergbau in Deutschland aus ökonomischen Gründen. Die Lagerstätte im Ruhrrevier ist jedoch bei weitem noch nicht erschöpft. Die Beendigung des Bergbaues führte zu einem Strukturwandel, der in den 1960er Jahren begann und heute noch nicht sein Ende gefunden hat. Er hat eine industrielle, stabile Raumstruktur mit neuem Leben zu füllen. Zwischen Ruhr und Lippe sowie am Niederrhein haben 53 eigenständige Städte und Gemeinde das historische Erbe aufzunehmen und gemeinsam die regionalen Stärken zu fördern. Die großen Flächenstilllegungen wurdenin den prosperierenden Zonen zu modernen Stadtquartieren mit unterschiedlichsten Nutzungen entwickelt oder haben in den Zwischenräume die Landschaften und Freizeitgebiete vergrößert<br>The article describes the prerequisites for a successful structural change in the Ruhr area during the last 60 years. Via the regional bundling of the potential in raw materials, geography, economy and population the region managed the termination of the coal and steel industry. More than 50 communities have to deal with the historic legacy and they have to promote the local features. The cessation of the intensive coal-mining phase requires creative ideas, intensive communication, coordination of a lot of stakeholders to ensure a development in the direction of new stable structures

O objetivo do trabalho é identificar áreas impactadas por material particulado da mineração do carvão e suas principais fontes emissoras em Moatize, propondo uma nova formulação de supressor de poeira de base vegetal como alternativa para reduzir a emissão de material particulado em mina a céu aberto. Através de metodologia cartográfica, buscou-se representar as áreas críticas contendo carga potencial poluidora, neste caso, partículas totais em suspensão (PTS) e material particulado respirável (MP10) procedentes do processo e logística da exploração do carvão. As variações na qualidade do ar em torno das áreas de mineração do carvão em Moatize foram avaliadas durante o período de 2015 em cinco locais e em duas estações do ano. Os dados de campo mostraram que as áreas mais impactadas pelas emissões difusas de partículas totais em suspensão (PTS) e material particulado com diâmetro 10 (MP10) devido à atividade de mineração do carvão em Moatize são Liberdade, Carbomoc, Minas Moatize e 25 de setembro. Este último é o mais impactado. Os dados revelaram ainda níveis de concentração de material particulado acima dos padrões estabelecidos no Regulamento de Normas de Qualidade Ambiental e Decreto de Emissão de Efluentes n° 67/2010 vigente em Moçambique. As concentrações de PTS atingiram 569 μg m-3 no mês mais crítico. As análises de elementos principais e de elementos maiores e traço no carvão bruto foram realizadas por Análise Elementar CHN e Espetroscopia de Emissão óptica com Plasma Acoplado Indutivamente (ICP OES). Na formulação básica do supressor de poeira foi examinado o supressor de extrato de Pinus e ácido γ-poliglutâmico (γ-PGA). A nova formulação contendo ácido γ-poliglutâmico resultou em supressor de poeira de base vegetal, biodegradável. A interface entre a matriz de carvão mineral e a película supressora foi examinada por microscopia confocal de varredura a laser. Na caracterização do supressor de poeira foram utilizadas técnicas de microscopia eletrônica de varredura e espectroscopia no infravermelho. O gênero Pinus é uma matéria-prima abundante, renovável e de baixo custo, que possui potencial químico para o desenvolvimento de novos produtos de alto valor agregado. Os resultados iniciais são promissores e representam não apenas uma vantagem ambiental, mas também um ganho importante para as comunidades localizadas nas imediações das minas de carvão.<br>Air pollution is considered a standard situation for the mining sector, presenting classic aspects of degradation of the biotic and abiotic environment. The objective of this work is to identify areas impacted by coal mining particulate matter and its main source sources in Moatize, proposing a new formulation of a dust suppressant which is plant base with an alternative to suppress the particulate matter in an open pit mine. By means of cartographic methodology, we intend to represent the critical areas with potential pollutant load, in this case, total suspended particulate (TSP) matter and respirable particulate matter (PM10) from the process and logistic of the coal exploitation. The variations in air quality around the coal mining areas at Moatize were assessed over the 2015 period at five sites and two seasons. The field data showed that the areas most impacted by the diffuse emissions of TSP matter and PM10 particulate due to the coal mining activity in Moatize are Liberdade, Carbomoc, Minas Moatize on September 25. The latter is the most impacted. The data also revealed a high concentration of particulate matter in these areas, with levels above the standards established in the Regulation of Environmental Quality Standards and Wastewater Emission Decree No. 67/2010 in force in Mozambique. The PTS concentrations reached 569 μg m-3 in the most critical month. The analyzes of major elements and major elements and trait in crude coal were performed by CHN elementary and inductively coupled plasma optical emission spectrometers (ICP OES). In the basic formulation of the dust suppressant the extract suppressor of Pinus and γ-polyglutamic acid (γ-PGA) was examined. The new formulation containing γ-polyglutamic acid resulted in a biodegradable plant-based dust suppressant. The interface between the charcoal matrix and the suppressor film was examined by a laser scanning confocal microscopy. In the characterization of the dust suppressor, scanning electron microscopy and infrared spectroscopy techniques were used. The Pinus genus is an abundant, renewable and low-cost raw material that has chemical potential for the development of new products with high added value. The initial results are promising and represent not only an environmental advantage, but also a significant gain for communities located in the vicinity of coal mines.

Abstract:

Ukraine is very rich in mineral resources. It contains iron and manganese ores, natural gas, salt, sulphur, graphite, flux limestone. Ukraine also has deposits of oil, bauxite as well as black coal. Mineral resources can be classified into three main groups: fuels, metals and nonmetals. Fuels include deposits of black and brown coal, natural gas and peat. The reserves of black coal are concentrated in two basins: the Donets and Lviv-Volynian Basins, deposits of brown coal are to be found in many places on the Right Bank. They form the large Dnieper Brown Coal Basin. The western regions of Ukraine contain small deposits of brown coal. Brown coal is used as local fuel for power stations, factories and plants, also in household heating.

Abstract:

A new method for demineralizing coal has been developed which is based on the osmotic pressures that occur when electrical double layers overlap. In this technique, coal is exposed to ferric ions in an acidic medium which causes the coal to lose electrons and become positively charged, thereby establishing ionic double layers in the vicinity of its surface. Inside the pores and crevices in which mineral matter is entrapped, the ionic double layers overlap and reduce the chemical potential of water, creating an osmotic pressure. The build-up of such pressure pushes the mineral matter out of the crevices, resulting in mineral liberation. Since the process, which is termed electro catalytically induced liberation (EIL), relies on surface-chemical reactions, the energy consumption is substantially lower than in conventional liberation processes based on comminution. Tests on several different seams of coal from varying geological locations have indicated that the process may be used to remove over 70% of the mineral matter present in coal. Mass balance studies conducted on a Wyodak coal indicate that approximately 90% of the ash removed is by the EIL mechanism, while the balance may be attributed to acid dissolution and the loss of material during handling. Scanning electron micrographs of the coal samples taken before and after treatment show morphological changes consistent with the proposed EIL mechanism. The technique has been used successfully to clean bituminous coals, low-rank coals and preparation plant refuse, and to further reduce the ash content of coals pre-cleaned by other means. A theoretical model has been developed to calculate the osmotic pressure that occurs inside a typical coal crevice during the EIL treatment. The changes in the aqueous chemical potential are calculated using semi-empirical equations derived from solution theory, while partial molar volume changes are accounted for in the final calculation of the osmotic pressure. The model indicates that pressures on the order of 4-7 atmospheres can develop inside crevices with walls 100-1000Å apart. These values are numerically consistent with those predicted by other models developed using different approaches.<br>Ph. D.

Abstract:

AbstractTwo forms of energy justice provide insight on Australia’s petroleum and coal problematic policy issues. First, distributive justice is used to cover the implications of low revenues from critical energy minerals; and fair allocations of resource income. Unfortunately, calls for true reform by the Australian community has resulted in a weak response from government. Second, cosmopolitan justice is used to consider the global effects of Australia’s fossil fuel extraction and use. Petroleum and coal exports result in GHG being emitted beyond the borders of the source country. However, there is now pressure in Australia to limit the opening of coal mines that supply the export market, but no such limit is applied to gas exports.

Abstract:

The article analyzes the mineral and raw material base of coal deposits of the Arctic zone of the Republic of Sakha (Yakutia), all of them were explored in the Soviet time in the middle of 40-50 years. The paper presents a comparative characteristic of the geographic and economic, mining and geological and geotechnological conditions of coal deposits in the basins of north rivers Jana and Indigirka. The qualitative characteristics of the coals have been studied, which showed that from the point of view of consumers from the local better are the coals of the Krasnorechenskoe and Tikhonskoe deposits, and the worst brown coals of Uyandinskoe and Kularskoe fields, which have a very high humidity and ash content. The article assesses the possibility of using coal for generation of electric and thermal energy during development of ore and placer gold deposits in the Arctic zone of the Republic of Sakha (Yakutia). The unit cost of electricity generation is lowest when using coal as fuel, which can be extracted from the Kular deposit. Taking into account the lower quality of the coal fields of Kular deposit, it is possible for the subsoil user to consider the issue of extraction and delivery of better-quality coal from the previously developed Soginskoe deposit. The results give the opportunity of a fuller assessment of the potential, role and place of coal, especially local coal, for the generation of electrical and thermal energy for use by mining and processing companies, focused on the implementation of ore and placer deposits development projects in Arctic zone.

Abstract:

Construction technologies are among the most critical in terms of negative impact on the environment. Burnt binders, primarily cement and air-lime, emit significant volumes of carbon dioxide and man-made heat. At the same time, a large amount of hydrocarbon fuel is also consumed for their firing. Therefore, to achieve sustainable development goals, the development of alternative binder formulations or innovative ways to produce traditional binders with low carbon emissions is necessary. The synthesis of low-carbon binder compositions that provide the required properties is based on the use of mineral or organomineral compositions with the use of highly dispersed fillers or modifiers. Technogenic resources are used as such fillers, including those extracted by the fuel industry � REA-gypsum, fly ash, bottom ash and their individual components. Recently, interest in aluminosilicate microspheres has been growing. They are isolated from ash and slag waste from coal power plants. When they are removed hydraulically, the calcium content in the waste decreases due to its fairly high solubility. The paper presents the results of a study of the physical and mechanical properties of cementless compositions for additive technologies based on aluminosilicate microspheres. Microspheres have a number of unique properties. The synergistic effect is achieved by combining a self-reinforced matrix, which ensures the stability of the mixture during the process of stone formation with a rapid increase in strength with the participation of microspheres, necessary when using compositions in additive technologies.

Abstract:

Carbon emission has increasingly become a topic of the day. Carbothermic reduction processes and energy generating units have for years used generic carbonaceous materials contributing to high carbon pollution. Ongoing investigations are showing good prospects. This paper corroborates a comprehensive review on the potential of biochar as an innovative and sustainable alternative to traditional carbon sources in pyrometallurgical processes, addressing the environmental ithreats caused by fossil fuel use, such as greenhouse gas emissions and global warming, and the urgent need for greener reductants in metallurgical operations. Derived from various biomass sources through pyrolysis, biochar exhibits unique chemical and physical properties that make it a promising reductant in high-temperature metallurgical operations, particularly in ferroalloy production and metal recovery from slags. The review delves into the characterization of biochar, examining its chemical composition, functional groups, and physical attributes such as high surface area, porosity, and thermal stability. These properties contribute to biochar's enhanced reactivity and efficiency in reduction processes. Multiple studies have demonstrated biochar's superiority over conventional reductants like coke and coal in various applications, including ferrosilicon production, copper slag cleaning, and iron ore reduction. Biochar's porous structure facilitates better gas-solid interactions and diffusion of reducing gases, leading to more uniform and complete reduction reactions. Its higher reactivity, lower activation energy, and potential catalytic effects from inherent mineral matter further enhance its performance in pyrometallurgical processes. The review also highlights the environmental benefits of using biochar, a renewable resource, in reducing the carbon footprint of metallurgical operations. However, the effectiveness of biochar can vary depending on its source material and production conditions, necessitating careful selection and potential tailoring for specific applications. Overall, this review underscores the significant potential of biochar to revolutionize pyrometallurgical processes, offering improved efficiency, lower energy consumption, and environmental sustainability in the metallurgical industry. This paper review only wood and woody biomass as well as herbaceous biomass are reviewed and discussed.

Abstract:

2023 Utah Mining Industry Summary The estimated combined value of Utah’s extractive resource production in 2023 totaled approximately $10.1 billion, including production of metals and industrial minerals ($4.0 billion), natural gas and natural gas liquids ($2.1 billion), crude oil ($3.8 billion), and coal ($314 million) (Figure 1). Utah’s diverse mining industry (metals, industrial minerals, and coal) accounted for $4.3 billion (42%) of total extractive resource production, a significant decrease of $531 million from the 2022 revised value (nominal dollars) and lower than peak values reached in 2011 ($5.3 billion, nominal dollars). Mining activities in Utah currently produce base metals, precious metals, industrial minerals, and coal (Figure 2). Base metal production contributed $1.9 billion and included copper, beryllium, molybdenum, and iron (Figure 3). Notably, copper alone accounted for 65% ($1.4 billion) of Utah’s metal production value. Precious metals produced in Utah include gold and silver, and 2023 production was valued at $250 million (Figure 3). Precious metal production value decreased 19% from 2022 to 2023, primarily due to less gold production, and base metal value decreased 16%, primarily due to less copper production. Industrial minerals produced in Utah include sand and gravel, crushed stone, salt, potash, cement, lime, phosphate, lithium, uintaite (Gilsonite®), clay, gypsum, and other commodities (Figure 2). The estimated value of industrial mineral production in 2023 was $1.9 billion (Figure 3), a 4.2% increase over the revised 2022 estimate. The most valuable industrial mineral group in 2023, estimated at $570 million, was construction material commodity group which includes sand and gravel, crushed stone, and dimension stone. The value of Utah coal production decreased 39% in 2023 to $314 million; production was much lower in 2023, and the average price also decreased (Figure 3). Notably, Utah is the only state to produce beryllium concentrate, potassium sulfate, and uintaite (Gilsonite®); of these commodities, beryllium, was included in the U.S. Geological Survey’s (USGS) 2022 list of critical minerals (U.S. Geological Survey, 2022). Lithium, also considered a critical mineral, has been produced in Utah since 2020, making Utah one of only two lithium-producing states. Throughout this report, production is designated in US short tons (t) or million short tons (Mt) unless otherwise indicated.
