When conducting mining operations on gas-bearing coal seams in the mines of Ukraine, gasification of cleaning and development workings often occurs, which often leads to explosions of methane-air mixture. At the same time, the process of methane release in the mine workings, on the one hand, has been studied quite extensively, and on the other hand, there are no unambiguous of the patterns of methane emission before and after the explosions. In addition, the lack of them did not allow the practice both for the requirements for the maximum allowable load on the clearing face, taking into account the gas factor, and the basic allowable requirements for the values of aerodynamic resistance of the excavation site. Therefore, the article examines the issues of methane control in mining areas of mines, working gas-bearing coal seams, inclined to the explosions of methane-air mixture and fires, at modern depths in the coal mines of Ukraine. This laws especially topically to use for liquidation of failures. It was found in the work that in the face of increasing loads on clearing faces, it is necessary to revise the regulatory documents that define the rules for designing of ventilation and removal of methane through pipelines beyond the excavation areas. Thus, new rules are especially necessary for the maximum permissible load on the face, taking into account the actual methane evolution and for the safe extubation of degassing systems during fires, and others. The new approaches should be investigated to include requirements for the maximum allowable values of the aerodynamic resistance of excavations of excavation sites and to take into account the removal of methane from the worked-out spaces beyond the sections through pipelines. It is shown that as a result of minimization of losses of air through the worked-out spaces methane accumulates in the worked-out spaces of facec. Thus such situation takes place in the conditions when only on 28,5% operating excavation areas even one method of taking of methane on pipelines was used, here the amount of the taken methane from a project size makes from 55% to 80%. Thus, it was established that it is necessary of the researches aimed at improving the efficiency of actions to reduce methane emissions to the atmosphere and prevent its ignition in the mines of coal mines.
Keywords: methane, excavation area, gasification, generation, coal seam.
