The key role of investment and innovation activities of coal industry enterprises in improving the environmental safety of regions specializing in coal mining is substantiated in the article. The coal industry enterprises are recognized by the world scientific community as the absolute leader in the field of negative impact on the environment and industrial production waste generation. In this regard, one of the most important tasks of increasing the investment and innovation activities of coal companies, the introduction of modern technologies should be not only an increase in labor productivity and production efficiency, but also a reduction of anthropogenic impact on the environment. Despite the obviousness of the presented thesis, the trends characterizing the coal industry as the most inert and low-innovative sphere, which follows the path of extensive development, continue to dominate. The insignificant increase in investments in fixed assets, periodically followed by a recession, the reduction of trapped and neutralized air polluting substances, the lack of demand for innovations in the coal industry, as well as their low impact on ensuring compliance with modern technical standards, procedures and rules, bear evidence of low responsibility of business entities and inefficient measures of state economic policy in the field of improving environmental safety in the commodity-dependent regions.

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 deals with the general tendencies and problems of the development of the Ukrainian coal industry in recent years. The main reasons for the problems and reduction of coal production in Ukraine due to the corresponding exhaustion of stocks as a result of long-term exploitation of coal mining enterprises are outlined. In addition, the unsatisfactory condition of the main equipment of the mines and its high level of deterioration and low rates of restoration of fixed assets are determined. The pace of investment and innovation processes in the coal industry of Ukraine today does not correspond to real needs and opportunities for increasing of coal production. The reformation and restructuring of coalmining enterprises is far behind the planned state program measures, including privatization processes, attracting private investment, improving approaches to management, closing unprofitable loss-making mines and building new prospective mines. The article highlights prospective directions of increasing coal mining, both operating mines and the possibility of building new explored reserves of energy and coking coal, in particular, in the Lviv-Volyn coal basin. The main reasons for the unprofitability of coal enterprises, untimely payment of wages to miners, problems of investment and innovation development of the coal industry are outlined. The complexity of the processes of voluntary association of communities in coal regions in the framework of the decentralization reform consists in the presence of environmental problems and the future closure of coal mining enterprises, negatively affecting the overall economic potential of the future united territorial communities. The paper proves that the strategic development of the united territorial communities in the areas of coal deposits (on the example of the Lviv region) is closely connected to the presence of coal mining enterprises there and the construction of new mines there. Strategic directions of innovative development of Ukraine's coal industry, the principles of reform and restructuring of the coal enterprises are defined.

Introduction. Coal industry is one of the main economy sectors of many countries. However, it poses a danger to the environment and human health. Since the Kemerovo region is a region with a developed industry, the problem of maintaining genetic homeostasis is highly relevant. Miners are exposed to various harmful factors that can act as genotoxicants and cause various DNA damage.The aim of the study was to explore the associations of polymorphic variants of DNA repair genes with chromosomal instability in coal mining workers.Materials and methods. Polymorphic variants of genes of enzymes of reparation DNA (XPD (rs13181), XPG (rs17655), XRCC2 (rs3218536), XRCC3 (rs861536), XRCC4 (rs2075685), XRCC4 (rs1805377)) and chromosomal aberrations in blood lymphocytes of 307 miners of coal mines in Kuzbass, 338 residents of the Kemerovo region who did not work in industrial enterprises were analyzed.Results. The frequency of chromosomal aberrations in the group of miners (4.01±0.14) was significantly higher than in the group of individuals who did not work in production (1.67±0.06, p<0.0000005). We found that allelic variants in genes XPD (rs13181), XRCC3 (rs861536), XRCC4 (rs2075685), are associated with the increased chromosomal damage in miners.Conclusions. Coal production has a negative impact on the genome of workers and can lead to the formation of cytogenetic disorders, which determines the need to develop measures for the comprehensive prevention of diseases caused by the accumulation of DNA damage. The results of the study will expand the existing understanding of the formation of the human genetic apparatus individual sensitivity to the effects of genotoxic factors, as well as formulate recommendations for coal mining workers in accordance with their genetic characteristics.Conflict of interests.

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.

The article considers the necessity to transform the existing economic development model of Kuzbass – the leading coal mining center in Russia – due to the increasing external risks, the problems of the coal sector in Russia as well as the adaptation of the region to a new reality. The author identifies five key factors of influence: decarbonization of the world economy; a fall in coal prices; the COVID-19 pandemic that has triggered the global crisis; long-term reduction of coal consumption in the Russian Federation; the formation of new coal mining centers in eastern Russia. As a result, based on a change in coal production in the region, three scenarios for the development of the coal industry and the economy of the Kemerovo region as a whole have been proposed. According to the author, with the existing regional model, the most likely scenario for Kuzbass in 10-15 years is a shock scenario, i.e. due to the decrease in global demand for hydrocarbons coal production in Kuzbass is expected to drop by 70-100 million tons per year, which could provoke a deep socio-economic crisis in the region. To avoid negative economic and social outcomes, it seems advisable to immediately start renovation of the Kuzbass economy with active participation of the state on the basis of a new reading of the model of territorial production complexes (TPC) which was successfully implemented in the region in the 20th century. The role of the basic industries of modern TPCs of the Kemerovo region can be assumed by clean coal technologies, petroleum chemistry and oil refining. At the same time, the author emphasizes that the restart of the model for the development of regional economy is possible only if the businesses (the owner of production assets), the government and the society reach the agreement and share full responsibility for the renovation processes of the resource territory.
