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.

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”.

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.

Full textAbstract:
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.

Full textAbstract:
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.

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

Full textAbstract:
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.

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

In coal mining, reclamation activities must be carried out by holders of mining business permits. In Samarinda City, there are 3 institutions that carry out reclamation oversight, namely the Ministry of Energy and Mineral Resources (Director General of Mineral and Coal), the Office of Energy and Mineral Resources of East Kalimantan Province and the Regional Reclamation and Post-mining Supervisory Commission. There are 3 main oversight mechanisms, namely, setting standards, observing facts in the field, comparing facts and formulating suggestions. Barriers encountered in supervising reclamation included limited human resources, funds, time, inactive status of mining companies, inactive supervisory bodies, changes in policies on minerals and coal. From the results of this study reclamation supervision is felt to be not optimal due to the lack of supervisors who are directly tasked with monitoring mining locations, difficult access and very long distances make monitoring difficult to carry out. The latest Law on Minerals and Coal has become one of the obstacles for local governments to carry out supervision, this is because the authority of local governments has been revoked. Minimal and sub-optimal supervision has resulted in damage to nature in Samarinda City, adverse impacts in the form of damage to the natural environment, damage to natural ecosystems, abandoned mine pits that have claimed as many as 39 people died in mining pits (voids).

Full textAbstract:
The mining industry of Poland is based mostly on coal and copper ores. Strict carbon emissions and the depletion of deposits will slowly phase out coal. Therefore, metallic ores and other mineral raw materials will dominate the extractive industry of Poland. Current measured resources of the largest deposits of halloysite and diatomaceous earth in Poland are over 0.5 Mt and 10 Mt, respectively. Halloysite and diatomaceous earth samples from halloysite Dunino deposits and Jawornik diatomaceous earth deposits (composed mostly of diatomaceous skeletons (frustules)) were subjected to mineralogical analysis, scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM-EDS) nanostructural, chemical, elemental, and mineral content analysis. Both these minerals have similar properties, i.e., sorption capacity and cation exchange capacity, and are used mostly for the same purposes, e.g., adsorbents, filler material, and filtration. Samples of Dunino halloysite consist of minerals such as halloysite, kaolinite, hematite, magnetite, quartz, magnesioferrite, rutile, ilmenite, geikielite, goyazite, gorceixite, and crandallite, with little impurities in the form of iron oxides. Occasionally, halloysite nanoplates (HNP) nanotubes (HNT) were found. Diatomaceous earth is composed mainly of silica-containing phases (quartz, opal) and clay minerals (illite and kaolinite). The frustules of diatoms are mostly centric (discoid) and have radius values of approximately 50–60 μm. Large resources of these minerals could be used in the future either for manufacturing composite materials or highly advanced adsorbents.

Firstly, the evaluation system of the priority sequence of mineral resources development was constructed from five aspects as mineral resources endowment, market conditions, technical conditions, social and economic conditions and environmental protection conditions. Then, the priority sequence model of mineral resources development based on grey correlation analysis was proposed. Further, taken the mineral resources in Hebei province as an example, the empirical analysis of the above model was made. Results show that the suitability of the province's mineral development from big to small is, in order, molybdenum ore, cement-used limestone, iron ore, gold ore, silver ore, coal, and etc. The algorithm is not only simple and intuitive, but also improves the efficiency and accuracy of the prioritize division of mineral resource development.

This research aims to determine the legal responsibilities of coal companies in fulfilling their achievements due to the export ban. This legal writing is included in the type of normative legal research using a legislative approach including primary legal materials and secondary legal materials collected through document study and analyzed using deductive legal material analysis using the syllogism method. This research examines the implementation of the Decree of the Minister of Energy and Mineral Resources Number 139.K/HK.02/MEM.B/2021 regarding the fulfillment and prioritization of domestic coal needs. The failure to fulfill the Domestic Market Obligation then gave rise to an export ban by the Ministry of Energy and Mineral Resources through the issuance of Circular Letter from the Directorate General of Minerals and Coal, Ministry of Energy and Mineral Resources Number B-605/MB.05/DJB.B/2021. The export ban then causes coal entrepreneurs to be unable to fulfill agreements with foreign companies. Non-fulfillment of achievements due to changes in Government policy in the form of an export ban is analyzed and categorized as force majeure so that non-performance, compensation or cancellation of the agreement cannot be sued. The legal responsibility that can be carried out by coal entrepreneurs in the event of an export ban is to submit a force majeure situation and prove that their party has been in good faith from the beginning until the agreement is in progress.

Full textAbstract:
Shaanxi is among the provinces with abundant coal resources in North China. These enormous coal resources (approx. 4143 Gt) are widely distributed in the Ordos Basin and its marginal fold belts. The main coal-bearing strata consist of the late Carboniferous Taiyuan Formation, the early Permain Shanxi Formation, the late Triassic Wayaobao Formation, and the middle Jurassic Yan’an Formation, which were respectively deposited in coastal plains and a lagoon environment, a continental environment, an inland open lake and a confined lake environment. The Permo-Carboniferous coals are low volatile bituminous and characterized by relatively high vitrinite content, which decreases from south to north, and from the lower coal seams upwards. By contrast, the late Triassic and middle Jurassic coals are highly volatile bituminous, but are respectively characterized by relatively high vitrinite and high inertinite content. Minerals in the Permo-Carboniferous coals, the late Triassic coals, and the middle Jurassic coals, are respectively dominated by kaolinite and calcite, quartz and kaolinite, and quartz and calcite. Furthermore, contemporary coals deposited in different coal fields or even different mines of the same coal field present different mineral characteristics. The Permain Shanxi Formation coals from the Shanbei C-P coalfield in the north of Shaanxi Province are characterized by higher kaolinite and lower carbonate contents compared to those from the Weibei C-P coalfield in the south of Shaanxi Province. The distinctive mineralogical characteristics of coals formed in different coalfields and different geological ages were ascribed to integrated influences of different terrigenous detrital input from sediment provenance, sedimentary settings (e.g., subsidence rate, sea transgression, and regression process), and hydrothermal activities.

Full textAbstract:
Primary and secondary mineral resources are of strategic importance to the EU economy. Montenegro, as a country candidate for membership in the EU, is required to follow (and later to implement) European policies, strategies as well as initiatives, including those related to mineral resources and the mining sector. The importance of providing access to mineral raw materials in the future is recognized by the EU, as well as meeting the needs of European industry, maintaining employment and ensuring further development. Considering the overall economic situation in Montenegro, it is important to encourge the mining sector and other industries based on the use of mineral resources in making a greater contribution to the development and sustainability of society as a whole and also increase the share of national GDP. The potential for discovery and utilization of primary and secondary mineral resources in Montenegro is demonstrated. The most important metallic mineral resources are bauxite, lead and zinc, while conventional energy resources include coal (oil and gas potential has yet to be proven). In addition, there are abundant non-metallic mineral raw materials - industrial minerals and construction materials. Secondary mineral resources, especially aluminous red mud (bauxite residue), are also significant and have been the subject of research in recent years. Tailings from flotation processes at operating and abandoned lead and zinc mines might also be of interest for metal recovery. Bottom and flay ash from thermal power plants, slag from steel production, as well as marlstone and limestone from the hanging wall of coal deposits may also have potential. Waste rocks could be used particularly for secondary aggregate production. A database was developed and the most important deposits of primary and secondary mineral resources in Montenegro were mapped during the RESEERVE project.

The dynamics of coal resources mining in Ukraine are analyzed in the article. It is proved that there were indices fluctuations, i.e. volumes of extraction, and growth rates during 10 years. The approximation of growth rates of coal mining resources by polynomial function using the trend line is made. It is determined that studied indices fluctuation have cyclical pattern, correlate to each other and depend on country`s economic and political situation. It is proposed to make forecasts of the extraction volumes based on national cyclical economic development. It is proved that balanced mining should solve the problem of mineral deposits sustainable exploitation. It is proposed to use the patent-protected author's methodology to forecast the development of complex systems to manage sustainable mining of coal resources in Ukraine. The developed model will allow managing volumes of extraction of technologically related minerals in correlation with the volumes of exploitation.

Extraction of the Arctic natural resources is the basis for the development of the Arctic Zone of the Russian Federation (AZRF), economic stability and energy security of Russia in the long term. The importance for the implementation of large-scale resource projects in the Far North is associated with logistics, which is provided by the Northern Sea Route. This article discusses the importance of the Arctic coal resources extraction for the integrated development of the Arctic region. At the moment, a number of large Arctic coal mining projects are being implementing. We analyzed their positive and negative aspects in the general context of the Arctic advancement, using general research methods of working with open data and publications. In addition, we have developed a step-by-step SWOT analysis of the Arctic coal extraction which includes five main points considering both the implementation of the Arctic coal mining projects and the overall socio-economic advancement of the Russian Arctic. As a result, we assessed the positive and negative aspects of the Arctic coal projects as well as the main opportunities that such projects open up and the threats that may affect the implementation. The study novelty lies in the application of the author's SWOT analysis methodology to the study of strategic prospects for development of the Arctic coal resources. It can be detailed by the research of the prospects of specific coal mineral resource centers.The author's methodology can also be applied to other types of Arctic mineral resources analysis.

Natural resources are one of the crucial objects in the dynamics of the life of the nation and the state, the management of this abundant natural resource is a very large responsibility of the state, the limitation of the state's ability is inversely proportional to the needs and potentials possessed by these natural resources so that the state makes natural resources as its business commodity in the utilization and management of natural resources. Business actors engaged in the utilization and management of natural resources need to compete with each other in order to obtain permits from the government and ease of investment, so that they can maximize the potential profits they have. This situation creates conditions for political lobbies so that the governing law can be adjusted to provide convenience for investors, one of which is the Mineral and Coal Law. This research will focus on examining the dynamics that occur to all stakeholders in the revision of the Mineral and Coal Law, by using a normative juridical research method using a legal and regulatory approach, so this research tries to map political strategies, political actors, and influencing factors. This research navigates to the hypothesis that the Mineral and Coal Law is a law oriented to business interests, so that environmental management and protection as a result of exploitation of natural resources is not optimal and futuristic.

Mineral exploration as the basis for the development of important mineral resources and economic construction, improving the efficiency of geological exploration is conducive to improving the quality of mineral resources. In this paper, the study of modern mineral resources exploration and utilization methods, drawing on the problems in geological exploration work, discusses effective countermeasures to improve and optimize the level of geological exploration from the perspectives of remote sensing technology and borehole database, etc., with a view to improving the efficiency of geological exploration and mineral search technology, so that energy production can achieve sustainable development and be free from the constraints of increasingly difficult mineral resources development. Based on remote sensing technology, GIS is a system derived on the basis of advanced science and technology and information technology, and its application to geological and mineral exploration can help relevant personnel to have foresight to understand the development of geological exploration and provide detailed data support for optimizing geological exploration work. Coalfield geological exploration arranges a large number of boreholes to find out the thickness of coal seams in the exploration area, the distribution pattern of coal seams and the spacing of coal seams, the characteristics of the top and bottom of coal seams, and the characteristics of coal quality. In the coal mining excavation, the technical personnel need to study the geological data of the borehole in time to design or adjust the excavation plan scientifically and reasonably. By implanting an electronic chip in the drill hole markers completed by drilling, the borehole coordinates, elevation, preservation of the borehole markers, and the website address of the borehole database management system are sent to the users in real time, providing geologists with convenient query services of borehole geological information. This paper proposes a geological and mineral exploration optimization method that integrates remote sensing technology and borehole database, and the relevant experiments prove the effectiveness of the proposed method.

The conditions of the formation of nonmetallic and ore minerals in limnogenic structures are considered. It has been established that lakes are natural enriches of a wide range of useful components - silicate, carbonate, water-soluble, ore, organomineral. The most significant minerals of modern lakes, in addition to water, are: sapropel, diatomite, lime and mineral salts. Deposits of sand, clay, oil shale, oil and gas, coal, phosphorites, zeolites, evaporites, bauxites, ferromanganese, copper ores, placer minerals, and some rare and dispersed elements are associated with limnogenic complexes of different ages. It is shown that a greater variety of minerals of ancient lacustrine complexes compared to modern ones is associated both with variations of lacustrine lithogenesis in the past and with post-sedimentation transformations of sedimentary matter. In particular, epigenetic enrichment of ancient lacustrine complexes with ore components is noted. It was revealed that hydrocarbons and diatomites of lacustrine genesis are of a higher quality compared to similar minerals of marine genesis. It is noted that evolutionary changes in the processes of accumulation of limnogenic minerals have affected to the greatest degree biogenic and chemogenic components. An example of this is the progressive accumulation of caustobiolites and the sulfate evolution of evaporites in lacustrine structures during the Phanerozoic. An analysis of the genetic characteristics of lacustrine minerals makes it possible to develop new exploratory traits of a number of sedimentary deposits.

Development of territories with excessive mineral resource use is traditionally based on income from mining and mineral resources processing. At the same time, their ecosystems are an important source of human well-being as they produce many ecosystem services. Reaching a compromise between two sources of territory development – abiotic services (coal mining) and ecosystem services – is one of the major objectives of sustainable development of the regions with excessive mineral resource use. This article assesses and compares ecosystem and abiotic services in the coal-mining area in Kemerovo oblast in monetary and physical terms. The results of economic evaluation of ecosystem and abiotic services are considered to be a key element in efficiency assessment of spatial organization of environmental management concerning sustainable development of the territory.

Lithium (Li) is an important strategic metal mineral resource, irreplaceable in the fields of modern industry, new energy technology, nuclear fusion, and energy storage devices. Li is an important supplement to traditional strategic metal mineral resources and has become an important avenue of mineral resource exploration. Therefore, there is an urgent need to establish a cooperative exploration model of coal and Li deposits to lay a theoretical foundation from the perspective of technical optimization and economic rationality. This study is based on the distribution characteristics of the Haerwusu coal–Li deposit, and the effectiveness of the response to exploration techniques, the economical and effective exploration techniques, the reasonable exploration engineering design, and resource estimation parameters is investigated. Therefore, the cooperative exploration model of the coal–Li deposit is established. The high-Li areas in the surface of the Haerwusu Li deposit is distributed near the B1 anticline or in the middle area between the X1 syncline and the B1 anticline, and the vertical distribution of Li content is irregular. The exploration techniques, exploration engineering design, and resource estimation are reviewed and optimized. According to the geological, geochemical, and geophysical conditions, a reasonable cooperative exploration model for coal–Li deposits is established from the two aspects of the coordination of multi-mineral exploration and the coordination of various exploration technologies. The determination of the coal–Li deposit cooperative exploration model has important practical significance for improving the resource security system.

In Article 112 of Law Number 3 of 2020 concerning Amendments to Law Number 4 of 2009 concerning Mineral and Coal Mining, there are provisions that require mining companies to sell a portion of their shares to the government or State-Owned Enterprises (BUMN). This obligation aims to control the exploitation of natural resources, enhance the state's control over strategic mineral and coal resources, and promote the sustainable utilization of natural resources. This journal comprehensively reviews the legal processes and implementation of the nationalization of share divestment, including potential challenges that may arise and their impact on the mining industry in Indonesia. The journal provides valuable insights into how this law governs vital natural resources for the country and contributes to the discourse on granting rights and state control over the extractive sector, with significant implications for mining policies in Indonesia and the potential for improved natural resource management.

Background - Coal Production, The Ministry of Energy and Mineral Resources (ESDM) noted that Indonesia's coal production will reach 606.22 million tons in 2021 from the planned 625 million tons or 96.99%. An increase of 7.2% compared to 2020 of 565.69 million tones. Since 2014, coal production has shown an increasing trend. However, production declined in 2016 and 2020. In 2016, coal production fell 1.1%, while in 2020, production fell 8.2%. The Ministry of Energy and Mineral Resources estimates that Indonesia's coal production in 2022-2023 will increase in the range of 637 million tons to 664 million tons. Meanwhile, the demand for domestic coal (domestic market obligations/DMO) in 2021 is 63.47 million tons or 10% of total production has been realized. The figure decreased by 51.87% from 131.89 million tons in 2020.

Gallium (Ga) is a typical scattered trace element that is irreplaceable in strategic sectors such as national defense, wireless communications, new materials, renewable energy, and healthcare. The coal–Ga deposit is an important complement to traditional Ga resources and has become a significant focus for Ga mineral resource exploration. Therefore, there is an urgent need to research the coal–Ga cooperative exploration model from both technical and economic perspectives. Taking the Heidaigou coal–Ga deposit as an example, the enrichment zone of coal–Ga is predominantly situated in the northern part of the exploration area, adjacent to the fault zone. The Ga concentration demonstrates a gradual decline from the north–central region towards the northeast and southeast. Similar vertical Ga distribution patterns are observed in adjacent drillings, with notably higher concentrations in the roof, floor, and parting layers. The cooperative exploration model for coal–Ga deposits is proposed based on the above features. The model employs a comprehensive set of cooperative technical methods, such as remote sensing, geological mapping, seismic exploration, drilling, petrogeochemistry, and well logging. The layout of exploration engineering and the concentration of Ga provide the basis for the estimation of Ga resources. Additionally, the model provides an important scientific basis for the improvement of the strategic coordination ability of Ga mineral resources.

Abstract Coal deposits that have been found in Tamalea Village, Bonehau District are one of the coal resources found in West Sulawesi Province, Indonesia. Coal study in this area will provide information about the characteristics of coal in the West Sulawesi area. This study aims to determine the initial composition of coal quality based on proximate analysis and the appearance of minerals in coal using microscopic analysis. The results of the proximate analysis of coal show that the moisture content ranges from 3.65% to 8.42%, the ash content ranges from 5.59% to 64.96%, the volatile matter shows a value vary from 17.69% to 62.83%, and fixed carbon ranged from 13.70% to 46.76%. The results of microscopic analysis showed the presence of several dominant minerals, namely clay, quartz, and pyrite. The presence of these dominant minerals affects the quality of coal, namely the high content of ash, and allows variations in the total sulfur content. The appearance of the mineral pyrite under a microscope shows that pyrite is formed through syngenetic and epigenetic processes. The most dominant processes in the coal samples studied is the epigenetic process. Syngenetic pyrites are mostly small framboids composed of tiny micro-crystals. Epigenetic framboids vary in shape and size with large and massive microcrystals. The pyrite content as a sulfur carrier shows a specific vertical distribution trend with the same pattern, namely the ash content and pyrite mineral appearance are higher in the coal seam adjacent to the floor compared to the coal seam adjacent to the roof.

The research method used in this article is normative legal research and through a literature study approach with secondary assessment of legal materials and juridical data analysis. The results of this study indicate that the regulations related to foreign investment in the mining sector still use Law Number 25 of 2007 concerning Investment and Law Number 3 of 2020 concerning Amendments to Law Number 4 of 2009 concerning Mineral and Coal Mining which are considered by the Government as a basic regulation that is still in accordance with current conditions in Indonesia regarding investment and mining of minerals and coal. Therefore, special arrangements are needed related to foreign investment in the mining sector, because the existing laws and regulations are unable to explain in detail the aspirations and needs of foreign investors in implementing cooperation contracts in mineral and coal mining activities.

Full textAbstract:
This paper presents the zonal geochemistry and elasticity characteristics of gallium- and lithium-rich No. 6 coalbed in the Haerwusu mine and discusses interpretation methodologies of coal-hosted gallium and lithium resources using lab-measured samples and field-measured wireline logs. The results demonstrate that both coal-composition-based and elastic-parameter-based classifications yield similar results, categorizing the coalbed into subzones related to coal quality. Material compositions, elastic properties, critical metals, and host minerals exhibit zonal distribution characteristics within the ultrathick No. 6 coalbed. Three-class classifications significantly enhance correlations among host minerals, elastic parameters, and critical metals, albeit with differing trends among classes. In classes II and III (ultralow- and low-ash-yield coals), boehmite and kaolinite primarily host gallium and lithium, respectively. In class I (medium-ash-yield coal), gallium is associated with kaolinite, while lithium lacks specific mineral associations. Constrained by wireline logs, a rock physics modeling strategy is proposed to link mesoscale coal compositions to macroscale elastic responses. Moreover, explicit correlations between host minerals and critical metals are established, connecting macroscale elastic responses to microscale gallium and lithium enrichments and exploring interpretation methods of coal-hosted critical metals. Preferred lithium interpretation methods include compositional ternary plots and elastic parameter cross plots, while preferred gallium interpretation methods involve boehmite-gallium and elastic parameter-gallium fitting. These findings may contribute to understanding the enrichment mechanisms and interpretation technologies of coal-hosted critical metals in ultrathick low-rank coalbeds.

The aim of the work is to study the methods of rational subsurface use in open-pit mining. The article outlines the main directions of rational and integrated use of mineral resources of the subsurface and the ways of their implementation in the open method of field development. The problems that prevent further expedient waste processing are identified. The achieved experience and prospects of complex development of deposits of ferrous and non-ferrous metals, mining and chemical raw materials and coal are analyzed. The problem of complex utilization of coals in industry in order to extract rare elements (in particular germanium and scandium) from the mineral component is considered. Special attention is paid to the specifics of transition to low-waste, resource-saving technologies of mining and enrichment production, to their efficiency and environmental safety at many mining enterprises. The directions of waste disposal of mining and processing industries and ways of their use for the internal needs of the enterprise, namely the use of overburden rocks of the Lebedinsky mining and processing plant, are investigated. Recommendations for the involvement in the development of man-made deposits and substandard mineral raw materials using physico-chemical methods for extracting useful components are given. It is noted that a comprehensive system of rational development of the country’s mineral resource base has not been built to date. This system is of great importance for the preservation of non-renewable natural resources of the subsoil and the successful implementation of the tasks of the National Project “Ecology”. A special role should be given to scientific research on the development of eco-innovative technologies for mining and processing of minerals.

As a potential strategic mineral resource, lithium (Li) in coal measures (including coal and parting) has attracted increasing attention from scholars globally. For a long time, Li in coal measures has been studied mainly on the macro-scale (whole rock); however, the microscopic characteristics of Li and Li isotope variations in coal measures are less well known. In this study, the No. 6 coal measures in the Haerwusu Mine were studied using ICP-MS, XRD, SEM-EDS, MC-ICP-MS, and LA-ICP-MS. The geochemical and mineralogical characteristics, the microscale distribution of Li in minerals, and the Li isotopes of Li-rich coal and parting in the No. 6 coal measure were investigated. The results show that the Li content in the No. 6 coal seam ranges from 3.8 to 190 μg/g (average 83 μg/g), which is lower than the parting (290 μg/g) and higher than the comprehensive evaluation index of Li in Chinese coal (80 μg/g). LA-ICP-MS imaging showed that Li in the coal is mainly contained within cryptocrystalline or amorphous lamellae aluminosilicate materials, and the Li content in lenticular aggregate kaolinite is low. The Li in parting is mainly found in illite/chlorite. The δ7Li of the coals was 3.86‰, which may be influenced by the input of the source rock. The δ7Li of the parting (7.86‰), which was higher than that of the coal, in addition to being inherited from the source rock, was also attributed to the preferential adsorption of 7Li by the secondary clay minerals entrapped in the parting from water during diagenetic compaction. Finally, by integrating the peat bog sediment source composition, sedimentary environment evolution, and Li isotope fractionation mechanism of No. 6 coal, a Li metallogenic model in the Li-rich coal measure was initially established. In theory, the research results should enrich the overall understanding of the Li mineralization mechanism in coal measures from the micro-scale in situ and provide a scientific basis for the comprehensive utilization of coal measure resources.

Full textAbstract:
Due to the gradual depletion of traditional metallic mineral resources, the search for new potential sources is an important issue. One such source is coal deposits. The extraction of metals from coal is a way to produce clean energy. This study presents the results of detailed research on geochemical features and mineralogy to understand the processes of microelement enrichment in the coal-bearing deposit of Shubarkol, in Central Kazakhstan. Modern analytical techniques were used to obtain information about the conditions and processes of trace element accumulation in coal, as well as the modes of occurrence of these elements. Geochemical data were analyzed using multidimensional statistical methods, including correlation, clustering, and factor analysis, which allowed us to draw several scientific conclusions. Numerous factors indicate that the enrichment of trace elements in sediments is controlled by clastic terrigenous material and low-temperature hydrothermal solutions circulating in the coal basin. The main sources of removal of trace elements from coal are ancient igneous rock complexes located within deposits that were directly involved in coal enrichment through secondary geological processes. According to estimates, the degree of enrichment of Jurassic coals at Shubarkol was close to the average value for world coals (0.5 < CC < 2), and coal seams were enriched with lithophilic and chalcophilic elements such as Ba, U, Yb, Co, La, Nb, Hf, Sc, V, Sr, Cu, and Zn. A correlation analysis of coal deposits revealed a significant correlation between main oxides and rare earth elements (REEs). The strongest correlation was between Zr, Hf, Th/Ta, and REEs. The positive correlations between Zr and Al2O3, Nb and Al2O3 indicate that these elements (Zr, Hf, Nb, Ta, and REY) are probably related to Al. The results obtained make it possible to consider coal as a potential mineral resource for the production of rare metals and serve as a guide for the industrial processing of the most important elements found in coal.

Full textAbstract:
Bioleaching exhibits high potential for the processing of low-grade complex mineral resources. With the development of the economy and an increase in demand, rare earth elements (REEs) in secondary resources, such as phosphogypsum, red mud and coal-related resources, are gaining more and more attention. In this review, the bioleaching performance of diverse microorganisms is summarized and compared for primary (mainly monazite) and secondary REE resources, based on publications from the past decade. The mineral characteristics of these REE resources are different, as they can be found in phosphate, sulfate, or silicate forms. Correspondingly, microbial species suitable for use in bioleaching differ. The most efficient bioleaching microbe for monazite is Paecilomyces sp., while Acidianus manzaensis is effective in processing red mud. Acidophilic sulfur oxidizers are suitable for processing acidic phosphogypsum. Acidithiobacillus thiooxidans could recover a significant amount of REEs from coal fly ash. In particular, monazite has a high REE content but extremely low bioleaching efficiency compared to that of secondary resources, supporting the understanding that bioleaching approaches are more competitive for minerals with low REE contents. Overall, great progress has been made over the last decade, as considerable REE recovery rates have been achieved, and the main metabolites of microbes were identified. However, numerous challenges still exist. Future efforts should focus on improving biorecovery efficiency, reducing the cost of cell-culture media, and exploring the interaction mechanism between cells and minerals, with an emphasis on mineralogical phase transformations and the molecular regulation mechanisms inside cells during the bioleaching process.

AbstractIn the early nineteenth century, political economists, politicians, and geologists debated the size and duration of the British coal supply. For mineral Malthusians, the argument about a dwindling supply sharpened anxieties about population pressure, fuel demand, and limited resources. They introduced a new sense of geological limits and long-term obligations into the theology of atonement. But for cornucopian liberals, the shift to a mineral energy regime supplied a powerful refutation to the Malthusian forecast. Inexhaustible coal promised growth without end.

Abstract Increasingly high uncertainty, complexity and variability of the mineral mining sector performance necessitates integration of digital technologies to improve business. Coal mines use DT much more less than the oil and gas industry. It seems a promising way to make use of the experience gained in the oil and gas industry to advance the Digital Field concept and Industry 4.0 as a basis for the sustainable tactical and strategic operation of business in coal mining. Digitalization of mineral resources and mineral reserves, geotechnologies and control provides a real-time picture of production and marketing. Furthermore, efficiency of coal exploration, mining, dressing and consumption is increased. It is expedient to use 3D modeling in evaluation of coal reserves, qualities and occurrence conditions to adapt mines to better and rival scenarios of development of structurally complex coal fields.

Full textAbstract:
The commercial coal resources of Western Australia occur in sediments ranging in age from Permian to Jurassic. The coal from each period has distinctive geographical, biological and geological characteristics which effects its utilization in industry and power generation. Currently the Permian intracratonic Collect Basin is the only producing coalfield in Western Australia. The annual production from this coalfield is approximately 6million tonnes, which is mostly used for power generation. Another Permian coal deposit in the Vasse Shelf, located in the southern part of the Perth Basin has potential for export to Asian markets. The Early Jurassic coal of the Hill River area in the northern Perth Basin has been fully explored and is ready for mining as a source for power generation. All three coal deposits represent a measured in situ resource in excess of 1500 million tonnes for Western Australia.
 Similar to the Gondwana coals of Australia, the coals are finely banded and the dominant lithotypes are dull banded with minor bright and bright banded types. The maceral composition of the coal is variable, however, the macerals of vitrinite and inertinite groups dominate, and the exinite and mineral matter contents are low, particularly in the Permian coals. On the basis of petrology of coal and the inter-seam sediments the depositional environment for the Permian coal was braided fluvial and fluvio-lacustrine, with marked fluctuations in the water table. The low water table accounts for fusain and inertodetrinite in the coal. The depositional environment for the Jurassic coal was of a low delta with some marine influence, supported by the presence of framboidal pyrite and acritarchs in the coal measures.
