Abstract: The European course towards decarbonization of the economy and energy systems is directly related to the reduction of the volume of extraction and use of fossil fuels. For Ukraine, large-scale restructuring of the coal industry, modernization of mining regions and thermal power are priority tasks. On the one hand, it is necessary to radically reduce the negative impact of extraction and use of fossil fuels on the environment, and on the other hand, we must ensure the effective involvement of the potential of mining systems in the sustainable development of territories, in particular by introducing modern innovative methods of using existing geological objects and mineral resources. In the article, using the example of coal massif of the Lviv-Volyn coal basin, a geological analysis of the formation of methane-containing coal gas traps is carried out and the dependence of the volume of coal gas release on the methane content of coal deposits is shown; for the extraction of a methane-gas mixture from a coal massif, a technological scheme is proposed, which is characterized by the fact that it step by step selects an underground block, to which gas production wells are drilled from the surface and coal gas is extracted, in the next step an adjacent underground block is selected, additional gas production wells are drilled and coal gas is extracted from the adjacent block, by repeating the blocks selection and gas extraction methane-gas mixture from all coal massif is removed; the scheme of an innovative complex has been developed that uses a methane-gas mixture of coal massifs to simultaneously produce of hydrogen, ammonia, and methanol, such complexes can be recommended for the sustainable development of mining enterprise territories.
