Relevance. Insufficiently high labor productivity at coal mining enterprises actualizes a study to increase the efficiency of their activities based on the factor of productivity growth. Purpose – substantiation of a possible increase in labor productivity with a change in the ratio of open and underground mining methods. Methodology – analysis of changes in labor intensity with various options for the share of open and underground development methods, as well as assuming an increase in production. Results. Issues of effective production and economic activity of coal industry enterprises are considered taking into account the factor of increasing labor productivity of workers. For the efficient functioning of coal mining enterprises, certain correlations should be fulfilled between the rates of change in the volume of coal production, labor productivity and the cost of coal production. Changes in coal production can be achieved mainly by the ratio of underground and open-cast mining. An approach to determining the level of labor intensity of work in the coal industry with a change in the ratio of underground and open coal mining methods is proposed; with a corresponding increase in labor productivity, the unit cost of production in the planning period is determined. The factors of growth of labor productivity in the coal industry are given: an increase in the utilization rate of combines for sewage treatment and bucket excavators for opencast mines; progressive changes in the design and operational characteristics of the main coal mining equipment; the use of imported equipment only in economically feasible mining conditions; the possibility of growth of stimulating factors to ensure the corresponding labor productivity of coal mining workers; increase in the share of coal from mines and opencasts with low cost of coal mining. Conclusions. The approach developed by the authors to determine the level of reduction in the labor intensity of work in the coal industry can be used in conditions of changing the ratio of open and underground mining methods, and accordingly, the change in the cost of production of one ton of coal as a whole for the joint-stock company can be forecasted.

Relevance. In the current context, the cost of coal products is growing. Labor productivity in coal mines and open-pit mines is significantly lower than the corresponding indicator in North America and Australia, a significant proportion of unprofitable enterprises, despite the fact that a third of the world’s coal resources and a fifth of the proven reserves are concentrated in the Russian Federation. In these circumstances, the substantiation of the strategic development of the coal industry on the basis of a SWOT analysis is of great importance. Purpose of the study is to substantiate the strategic vision for the development of the coal industry, priorities for the functioning of coal mining enterprises. Research methods are scientific generalization, method of system analysis and analogies. Results. In the course of the study, the possibilities of functioning of coal mining enterprises, threats to the coal industry, strengths and weaknesses of their activities were identified. The ability to function is determined by the presence of huge coal reserves in Russia, the leadership in its production and export, and a significant share of coking coal grades. The identified threats include: a significant decrease in prices on the world market and coal consumption in the domestic market, an increase in the average transportation distance and the risks of introducing environmental restrictions. The weaknesses in the activities of coal mining enterprises, requiring appropriate measures to be taken to liquidate them, come down to the following: increased operating costs, low labor productivity, a significant number of small mines and open-pit mines that hinder the effective development of the industry as a whole. At the same time, the strategy for further development should focus on the strengths of the coal mining enterprises. These include lower capital investments based on conventional fuel, significantly lower than in the oil and gas industry, therefore, during the period of ensuring sustainable development of the economy as a whole, the development of the coal industry will require lower costs, which creates conditions for the development of other related industries, the possibility of introducing an economic mechanism of inter-fuel competition, as well as the effective functioning of the market structure within the “free” oligopoly. Increasing the competitiveness of coal mining enterprises requires the use of accelerated depreciation methods at export-oriented enterprises, the introduction of problem-solving technology at large coal mining enterprises, the establishment of a rational ratio of the used imported and Russian equipment, and the containment of the growth in the cost of railway transport services. The focus on the implementation of the concept of creating a digital industrial enterprise in the industry plays a special role. A number of measures should be taken to improve financial stability. Conclusions. The identified opportunities and threats, as well as the strengths and weaknesses of the activities of coal mining enterprises, serve as the basis for substantiating the “Strategy for the development of the coal industry”, determine promising directions for the future of coal mining enterprises.

The article deals with the development of coal industry of the Donetsk basin and technical support of mineral fuel production in the mines of the region in the late XIX - early XX centuries. The last decade of the XIX century. characterized by the concentration of coal enterprises, which led to the widespread implementation of steam lifting, drainage and ventilation devices, the use of dynamite instead of gunpowder in the conduct of underground mining; construction of better equipped and capital super-mine technological complexes. It is noted that the coal mining enterprises of Donbass in 1914, although technically lagging behind the leading capitalist countries, were relatively modernized and showed positive tendencies to their further improvement.One of the major drawbacks of the beginning of the development of the Donbass coal industry was the lack of advanced machinery.  By the middle of 1914 at least 12 types of felling machines were already actively used in the mines of the Donetsk basin, moreover, the supply of disk and rod machines was carried out by British factories, chain - American, shock - British, American, and German. Cutting machines belonged to the heavy type and cost several times more than percussion. Cutting machines were driven by pneumatic or electropneumatic engines. It was emphasized that miners in search of maximum optimization and productivity of coal mining were increasingly concerned about the technical improvement of their enterprises, as the introduction of appropriate innovations could significantly affect the economic feasibility and profitability of enterprises. This was required by the technological necessity in connection with the expansion of production and the constant shortage of labor. Foreign owners and shareholders who tried to introduce advanced technologies of their countries played an important role in the implementation of innovations. In addition, technical improvements in mining processes not only brought economic benefits to their owners, but sometimes indirectly improved working conditions and safety at mining facilities.

The Cost

In recent years, there has been a decline in the efficiency of coal mining by traditional methods. On the one hand, the volume of coal outside the contour of the cut, which is economically impractical for open-pit mining, is increasing. On the other hand, when using underground geotechnology, the cost of production exceeds the cost of performing mining operations using open geotechnology, this is due to differences in the factors of operation of the open pit and the mine. This circumstance determines the use of open-underground technology for mining coal reserves outside the contour of the open pit as an actual and promising direction. This article describes a methodological approach based on the use of technological schemes for the preparation and treatment of reserves of powerful shallow coal seams, the justification of the parameters of combined geotechnology with a coordinated and balanced development of open and open-underground mining operations with the distribution of reserves for open and open-underground mining of coal reserves beyond the limit contour of the open pit, the preparation of excavation sites directly from its workings and the coordination of production capacity and the speed of their development. Its application will increase the production capacity of the coal mining complex without additional environmental burden and will provide an increased return on investment.

Active Coal

Coal has long been a valuable natural resource in the United States throughout the country’s history.  European settlers began to use coal in the late 1740s and, as energy demands increased, coal production climbed from 9.3 million tons in 1850 to 750 million in 1918. Eventually coal replaced wood as the primary energy source, and by the 1940s coal provided up to 75 % of US energy. Bituminous coal was the first target of US coal mining. This changed between 1843 and 1868 when more anthracite began to be mined. Used in iron smelting, this cleaner and smokeless alternative became the preferred fuel in cities. However, limited anthracite resources could not fulfill increasing demand. Production of sub-bituminous coal began to slowly rise, and in 2010 it was greater than bituminous coal production. Until the 1950s, coal was primarily mined using underground methods. By the 1970s, however, the development of cheaper surface mining proved a viable alternative for the US coal industry. In the last 10 years, coal production in the United States has dropped 37 %, from about 1.1 billion to about 702 million tons in 2017, and the number of active coal mines has also declined. Coal consumption declined as a result of an increased supply of cheaper and cleaner natural gas, growth of renewable energy sources, and enforced environmental regulations. Coal provided close to 60 % of US electricity in the mid-1980s, but only about 30 % in 2017. While there were 606 coal-burning power plants in 2007, only 359 were operating in 2017, with the remainder closed because of aging infrastructure and stiffer environmental guidelines. Coal mining is an industry in transition as new technologies and policies continually reshape the energy landscape. With increased competition from other sources of energy and a steady decline in the number of coal-fired power plants, the coal industry needs innovations to continue.

The article considers one actual method for development coal deposits in the Kuzbass by open-underground mining. The scientific and practical advantages of the proposed method due to the use of common infrastructure of coal mine and a modular mine site (subsequently transformed into a mining and technological structure operating according to the mine – longwall scheme) are presented. Currently, a development strategy for Kuzbass until 2035 has been developed. As part of the strategy, a draft program for subsoil use is being formed in the coal industry department. The program should take into account all the positive and negative aspects associated with coal mining in cities and municipal areas and also their prospects. In the Kuznetsk coal basin, 42 mines and 52 opencast mines are mining, of which 12 enterprises use partially unified infrastructure. According to the results of open-underground mining work conducted by the laboratory of the Institute of Coal and Coal Chemistry of the Siberian Branch of the Russian Academy of Sciences (Institute of Coal SB RAS), the list of sites includes favorable mining and geological conditions with incidence angles of up to 18 degrees. As open-pit coal production increases, many sites encounter such a parameter as maximum allowable (boundary) strip ratio. At the stage of preparing the feasibility study for the development of a coal deposit, this coefficient is calculated first of all, since duration of enterprise’s work and its economic component depend on it. In order to increase parameters, it is necessary to carry out transition from open works to underground. As a result, coal mine will not work at a loss, providing production with an economically disadvantageous strip ratio.

Hazardous and ineffective mines were closed, and a number of underground and strip mines of a modern technological level were built as a result of the restructuring of the coal industry in Russia. However, safety in the coal mines continues to be one of the urgent issues nowadays. In underground coal mining, the main types of risks are processes occurring in the rock mass as a result of mining operations. It is necessary to realize timeous and the most accurate prediction of harmful events, which occur during a development of coal fields, to increase the efficiency and reduce the cost of coal mining. The most optimal and, at the same time, comprehensive approach to predicting possible natural hazardous events in the process of modern coal mining are considered in this article. The results of implementation of integration of different methods of geodynamic and geomechanics researches are presented in this paper.
