The work purpose is determination's effective parameters of a way of an intensification of degassing and decrease gasdynamic activity of coal seams hydrodynamic influence in the bottom and top part overhand's longwall. Methods of researches - mine experimental researches. On the basis of mine experimental researches of process of hydrodynamic influence on a coal seam l7v - "Pugachevka - vostok" horizon of 1146 m through technological wells in the lower part of longwall №3, №4 station distance 20+1 and №5, №6 station distance 35+5 and №1 on the station distance 36+8 in the top part of longwall dynamics of change of daily average concentration of methane in an air-gas mix before hydrodynamic influence on mining massive, and also the sizes of zones of its processing has been defined. By results of definition of the sizes of the area of zones of processing and change of daily average concentration of methane taking into account background concentration and daily quantity of air on proceeding stream from a site №65 coefficients of degassing of a coal seam in zones of its processing through technological wells №3, №4-0,6, and №5, №6 - 0,45, radius of processing of 24 m both 20 m accordingly and coefficient of extraction of coal - 0,002 are defined, and in a zone of processing by well №1 - the processing radius has made at degassing coefficient - 0,45. Efficiency of hydrodynamic influence as way of an intensification of degassing and decrease gasdynamic activity in a zone of influence of technological wells is established. Coal-face works are spent without signs gasdynamic's effects. HYDRODYNAMIC INFLUENCE, TECHNOLOGICAL WELLS, DAILY AVERAGE CONCENTRATION, MASSIVE'S DEFORMATION, DEGASSING COEFFICIENT.
