Abstract. The eastern regions of Russia have a substantial potential for expansion of steaming coal production. The majority of coal deposits in the eastern regions are located close enough to the objects of the Asian super ring. The large coal reserves make it possible to consider it as a reliable fuel source for power plants for a long-term horizon. The coal reserves suitable for using at power plants of the Asian super ring are estimated in the paper by subject of the federation of the eastern regions for operating and new coal producers. The coal deposits of the eastern regions that are promising for the construction of power plants of the Asian super ring are presented. The paper describes both the coal deposits of the eastern regions that are considered in the projects for power plant construction and included in the program documents and the coal deposits that are not included in the program documents. The coal reserves of these deposits and the possible volumes of its production are estimated. The key qualitative coal characteristics of the deposits: heating value, and ash, sulfur, moisture content are presented. The mining-geological and hydrological conditions for deposit development are briefly characterized. The coals of the eastern regions are showed to contain valuable accompanying elements. It is noted that the creation of industrial clusters on the basis of the coal deposits is the most effective from the standpoints of the economy and ecology. The favorable and restraining factors in development of the described coal deposits are estimated.

In recent years, Mongolian coal export has grown and gained great importance for the country. The significant resources of high-quality coal and demand for coal in the international market contribute to the augmentation of Mongolian coal export. The expanding coal supplies to the international market affect greatly the development of coal mining in Mongolia. The paper presents the status of coal resources and the characteristics of the most ambitious projects for the development of coal export. The most significant coal development projects are mainly related to the development of deposits in the South Gobi region. Foreign companies that hold licenses for the development of deposits take part in the development of coal deposits. Current and potential future restrictions on the development of coal export are given. The main of them are the lack of access to the seacoast, as Mongolia is a landlocked country; state of transportation infrastructure; the availability of resources for the development of production, and the geopolitical conditions affecting the demand for coal in the world market. Coal exports can be delivered to the international market from the seaports of China and Russia, through the territories of these countries. Further increase in coal export from Mongolia depends on the development of transportation and production infrastructures; the situation in the international coal market; the availability of resources for the development of deposits; and opportunities to increase the volume of exploration. In the future, Mongolia could become one of the world's major coal exporters.

The paper presents an analysis of trends in coal industry development in Russia's eastern regions and its significance for the national coal industry. The study focuses on the prospects for the coal industry development in Russia's east and the potential directions of coal use there. The coal production and supplies for export are projected for the period up to 2035.

The Republic has significant resources for the development of mining, export and domestic consumption, including the energy needs of the republic and neighboring regions. The article provides a retrospective analysis of the supply of Yakut coal for energy needs and the structure of capacities by energy resources. The estimation of power-generating coal resources, including low-grade products of coking coal processing of the Republic of Sakha (Yakutia), is given. Characteristics of coal deposits are presented, which are useful for energy needs. Projects for the development of coal-fired energy in the Republic of Sakha (Yakutia) are presented. The Republic of Sakha (Yakutia) has significant coal resources for the development of coal-fired power plants. Coal power facilities play a closing role in meeting the demand for electricity and heat. The use of coal for the development of coal-fired energy in the Republic of Sakha (Yakutia) can be determined by the development of mining industry, the construction of power plants of small capacity in isolated areas, as well as the possibility of exporting coal-fired power plants.

In the article, the role of coal in the energy balance of the Republic of Sakha (Yakutia) is assessed by factoring in significant coal reserves, including low-quality and local coal in hard-to-reach areas. The research was carried out using system analysis methods. To this end, the retrospective dynamics of production and consumption of fuel and energy resources in retrospect and estimates were considered. The estimates were obtained by analysing reference documents, available resources for coal mining and the calculations performed by the authors. The production and consumption of fuel and energy resources of the Republic of Sakha (Yakutia) were analysed. It was shown that coal comprises one of the main resources for power and heat generation, along with gas and water resources. Its share in the consumption of primary fuel and energy resources in 2020 amounted to 34.6%. According to the calculation results, the coal production in the Republic in the future may reach 43 million tons, which will lead to the stabilisation of the export supply of coal and the demand for fuel at power plants and boiler houses in the Republic and neighbouring regions. Projects for developing the coal-fired power industry in the Republic rely on the consumption of coal from the South Yakut coal basin. In the optimal forecast balances, the share of coal generally remaining unchanged may range from 37.8 to 38.7% by 2035. It was established that the potential for coal consumption may increase from 3.5 million tons of coil, equivalent in 2020 to 4.1–4.8 million tons of coil equivalent per year. Mining opportunities significantly exceed their demand, both at present and in the future. A system analysis of the obtained results allowed the main factors affecting coal consumption in the long term to be identified. Coal mined in the South Yakut basin comprises a reliable fuel source in the zone of centralised energy supply in the future. In areas of the Republic of Sakha (Yakutia) having underdeveloped infrastructure and low population density, coal from local deposits becomes an alternative to imported fuel if their development is economically and socially justified.
