Abstract: A retrospective assessment of the emission of coal methane in the Kuzbass during coal mining by underground and surface methods, as well as the subsequent handling of coal extracted from coal mines, are carried out. The forecast of annual emission of coal methane in the region is presented. The content of hydrogen, oxygen, carbon monoxide, carbon dioxide, methane, ethane, ethylene, acetylene, propane, propylene, butane and isobutane in gas mixtures taken under mine conditions in mine workings, goaf and coal seam is studied by gas chromatography. It is shown that the largest volumes of methane are removed from coal mines by ventilation systems at its low concentrations in the air-methane mixture. Promising areas of coal methane processing including production of thermal and electrical energy as well as utilization of low-concentration ventilation methane are discussed.
