Poljakov of National Academy of Sciences of Ukraine popup.description2  The object of the study is the ventilation of excavation areas of coal mines. The purpose of the work is to determine the possibility of reversing the air flow in the mine workings of Public Joint-stock Company "РokrovskoeMineGroup" under the conditions of an active fire in an isolated space of the 12th southern “bis” of lava block 10 in 2018. Research methods - generalization and analysis of results, methods of mathematical statistics, calculations using standard methods. As a result of the work, the course of eliminating the consequences of the explosion that occurred in 12 southern “bis” lava of unit 10 of Public Joint-stock Company "РokrovskoeMineGroup" was analyzed, the analysis of air distribution and mode of operation of the degassing system after reducing leakage of air through the developed area 12 of southern “bis” of block lava 10. “Recommendations on ensuring safe working conditions in connection with the impossibility of carrying out planned reversing of the air flow in the mine workings of Public Joint-stock Company "РokrovskoeMineGroup" in the presence of unauthorized about an isolated fire in the workings 12 of the southern "bis" of lava block 10". The possibility was agreed not to carry out the planned (summer), provided by the safety regulations, after changing the ventilation pattern and putting the main fan installation DYTDR3293TD8A Howden on the ventilation shaft number 3 into operation, reversing the air flow in the mine workings of "РokrovskoeMineGroup" until the end of emergency response work , write off the fire and resume work on the excavation site 12 of the southern “bis” of lava unit 10, subject to compliance with the condition that the safety recommendations developed are followed. The results of the implementation of the development - the application of the developed recommendations allowed to ensure gas safety in the conduct of mining operations, which is of great socio-economic and environmental importance.
