“…it disturbs land; results in flooding of territories; introduces changes in hydrogeological regime of underground water; pollutes air; and favours accumulation of technogenic waste and land amortization. In turn, coal preparation factors into the formation of large-scale sludge collectors and ground contamination; a process of coal combustion by thermal power plants factors into air pollution, accumulation of greenhouse gases etc [13].…”

Topical issues concerning the low efficiency of underground coal mining from thin and very thin seams as well as the problems of reserves left in mine fields by the closed-down enterprises resulting in substantial coal reserve losses have been highlighted. Alternative use of the unextracted energy resources is their physical and chemical transformation with the change in aggregate state including the possibility to generate valuable chemical and energy products capable of substituting certain share of natural gas being imported. Attention has been paid to budget reallocation in the process of coal enterprise restructuring to invest the projects of nontraditional techniques aimed at physical and chemical coal transformation; among other things, it concerns in-place construction of energy generating enterprises for underground coal gasification. Results of the studies concerning the analysis of the world 50-year interest in the techniques of gasification and hydrate formation explained and described in the top scientific journals being among those added to such scientometric data bases as Scopus and Web of Science; they confirm the expediency of the scientific tendency development in Ukraine. Innovative conversion scheme for solid fuel has been proposed; the scheme involves the integrated use of the generated energy and chemical products in the process of in-place coal gasification. Development of systems to gasify, cogenerate, and form hydrates at the territory of coal mines will make it possible to process coal in place with energy, heat energy, and chemical raw material generation depending upon the situation in energy market and chemical market.

“…Thus, the operating efficiency of underground gasifiers mainly depends on the intensification of the processes occurring in the reaction channel of the oxidation and reduction zone, as well as on the presence or absence of equally important mining-geological, hydrogeological and technical factors. Thermal energy released during the gas generation process is partially transported with it and can be utilized in gas outlet wells or on the surface using special heat exchangers [149], [150]. At the same time, a significant part of the heat remains in the mined-out space of the underground gasifier (accumulated in the caved roof rocks) and extends to the surrounding mass.…”

Purpose. The research purpose is to perform a critical analysis of methods for intensifying the gas generation process in the reaction channel to improve the efficiency and economic feasibility of coal seam gasification technology. The paper studies in detail the aspects of the chemical mechanism and technological parameters of this process in order to determine the possibilities for improving efficiency and productivity. Methods. The review study is based on an approach that includes an analysis of the underground coal gasification development, the study of chemical reactions in the reaction channel, the study of the influence of factors such as temperature, pressure, blast and producer gas composition, etc. The experimental research data systematization is based on in-depth analysis of scientific papers published in peer-reviewed journals. Findings. The systematized results of research into nine main methods for intensifying the gas generation process in the reaction channel during underground coal gasification are presented. The factors having the greatest influence on gas generation in the reaction channel have been identified. Originality. Research results indicate the possibility of improving the process of underground coal gasification. The revealed relationships between different factors contribute to a deeper understanding of the chemical and physical processes in the reaction channel. Practical implications. The results obtained can be used to optimize the underground coal gasification process, increase the productivity and quality of gas generation. The specified results can serve as a basis for further scientific research and innovative developments in obtaining an alternative type of fuel.

“…In the near future, a sharp increase in the use of well geotechnologies is expected, which results in pumpable state of minerals in the place of occurrence and transporting them along wells to the earth's surface [Falshtynskyi et al, 2012;Lozynskyi et al, 2018]. Significant achievements of recent years in the underground coal gasification technology and underground gasifier thermal energy recycling open up new prospects for this coal geotechnology [Gayko & Kasyanov, 2007;Falshtynskyi et al, 2016]. This technology can be part of a single complex of coal methane mining, traditional and geotechnological development of coal seams.…”

The influence of the humanitarian component (sacred, religious, social factors) on the origin and initial development of mining activity, metallurgy origin, the first natural and technical knowledge accumulation and application forms are considered. The hypothesis of the metallurgy occurrence in the stable communities of primitive miners is considered. The ideology component of important technological inventions, created in an environment where both these phenomena were extremely close, is shown. The organizational forms of mining activity in which sacred factors played an extremely important role from archaic mining communities to medieval religious orders (in particular, Cistercians) were analyzed. The role of traditions, beliefs and professional knowledge in the formation of the special mining communities' nature from ancient time to the Middle Ages, their heritable resistance and isolation have been revealed. The possible ways of future mining progress are described, for which the scientists' and entrepreneurs' substandard ideas and predictions are used.
