Abstract. The article presents an analysis of modern geotechnological methods of gas extraction from coal technogenic deposits. Special attention was focused to methods of complex resource development, which concentrated in mine filled rock dumps and sludge accumulators of coal-processing factories, by means of their thermal conversion. The processes of such deposits development are carried out in different ways, and the raw materials for them are different coal-contained materials, depending on its particle size, physical, chemical and technological properties. Intensive research in this field promoted the significant advantages of similar processes, such as low pressure, lack of oxidizing agents, simplicity of process organization and low capital intensity.

The goal of the research is to study the processes of thermal decomposition of carbon-contained raw materials in order to obtain additional information, regarding the following question: what technology should be applied to obtain more combustable gas for further commercial application.

The work describes physical-and-chemical methods of thermal impact on solid carbon-contained raw materials, which was considered as a binary mixture of coal and rock, in an oxygen-free medium or with the use of oxidants. These processes are characterized, first of all, by the decomposition of the organic matter, the recombination of the splitting products and the formation of thermodynamically stable final substances: the solid residue, the liquid products and the gas phase.

The article presented the researches results of catalytic transformations taking place in the structure of a coal substance. Various versions of the use of catalysts in the processes of physical and chemical transformations of coal were proposed. The existing methods of impact on the mine medium in order to identify the most perspective directions for the development of new methods in the field of geotechnological processes of gas extraction from coal technogenic deposits were analyzed. A new method for thermal impact on carbon-contained materials in order to obtain some industrial gases was developed.

Keywords:  mine medium, thermal impact, coal-contained materials, geotechnology.
