Poljakov of National Academy of Sciences of Ukraine popup.description2  The object of research is the processes that take place in a tense gas-saturated coal massif under hydrodynamic influence through long technological wells. The subject of research - the parameters of the method of hydrodynamic impact on a steep coal seam. Research methods - based on mine experimental studies on the application of the method of hydrodynamic impact on the coal seam k8 - "Kamyanka" working face №95-1146 m, the process of gas evolution from the treated area after exposure to the lower part of the working face section №95 and analytical calculations of hydrodynamic efficiency The dynamics of the change of the average daily concentration of methane in the initial air flow from the site, as well as the radius of the zones of intensive gas evolution are determined. The concentration of degassing of coal seam sections through technological wells № 6, № 7 per formation k8- "Kamyanka" and № 12 per formation by the concentration of methane in the initial air flow from the site, daily coal production and the amount supplied for air ventilation. l7v - "Pugachivka", radius of zones of intensive methane release and coefficients of formation degassing intensification was determined. The efficiency of application of the hydrodynamic influence method for intensification of degassing and decrease of gas - dynamic activity of coal seams sections in the zone of influence of technological wells is established. Mining works in the lower part of the working face of the site № 95 were carried out without signs of gas-dynamic phenomena.
