Poljakov of National Academy of Sciences of Ukraine popup.description2  The object of the study is the gas safety of excavated areas of coal mines. The purpose of the work is to develop recommendations for the release of outgoing air stream from the preparatory face into a fresh stream of air entering the preparatory generation, agree on a project for the isolated removal of methane from the developed lava space beyond the excavation site through a rigid pipeline due to general depression and draw conclusions about the possibility of termination of degassing excavation site. As a result of the work, the mining technical characteristics of the excavation sections and dead-end workings of the mine "Western-Donbaska" PSS "TernivskеMineGroup", "DTEK Pavlogradugol" were analyzed. Developed "Recommendations for ensuring gas safety when conducting a dead-end production of the southern main conveyor drift of the C5 reservoir when releasing the fresh air stream entering its airing outgoing air ventilation stream from the preparatory face of the southern main haulage drift of the C5 reservoir", "Recommendations for gas supply the security of the excavation section 881 of the c8n lava of the reservoir when using isolated methane removal from the open space beyond the limits of the excavation section through rigid pipelines due to general mine depression "and" Conclusion on ensuring gas safety of 863 lavas of the c9 stratum when using a return ventilation circuit, type 1-M, with isolated methane withdrawal from the exhausted space outside the excavation area due to uncontrolled mining due to general depression without using roof degassing ". Agreed "The project of the isolated removal of methane from the developed space 881 of the lava of the c8n reservoir outside the excavation section of a rigid pipeline due to a general depression." The results of the implementation of the development - the application of the developed recommendations helped to ensure gas safety in mining, which is of great socio-economic and environmental importance.
