Poljakov of National Academy of Sciences of Ukraine popup.description2  Purpose of researches: development of theory (theoretical concepts) of nature and mechanisms of gas-dynamic phenomena taking into account geological and geomechanical conditions and factors of their occurrence in the boundary-stressed coal and rock massif and development of recommendations for improvement of technologies for their prediction and prevention. Object of researches: gas-dynamic and geomechanical processes in the workings of coal mines. As a result, the contribution of methane phase components to the total methane bearing capacity of the coal seam is estimated, a continuous model of gas-dynamic phenomena occurrence in gas-saturated coal seams is developed, the influence of geological conditions on the peculiarities of gas-dynamic phenomena in the coal massif is determined. depth of mining operations, developed a mathematical model of two-phase filtration of liquid and gas in the deformed bottom hole zone of the emission hazardous coal seam, established integrated indicators for estimating the geomechanical and gas-dynamic states of the rock mass, developed a mathematical model of stress-strain and gas-bearing with frame and anchor mounting, developed a method of automated calculation of the parameters of the process of gas-dynamic phenomena in the mine ventilation network, developed recommendations for safety research and improvement of technologies for mining coal seams, dangerous for gas-dynamic phenomena.
