The operation purpose - work by definition and concrete definitions of parameters of method of an intensification of inflow of gas in methane drainage boreholes, definition of an optimum drainage radius of methane, increase of operations safety. Methods of studies - analytical and mine experimental. On the basis of mine experimental researches of process of hydrodynamic influence on a coal seams k8 - "Kamenka" of a lease №95 and process of a gas emission of the processed working areas after its conducting in bottom of bands №4 and №5, completed by shield aggregates, has been instituted a time history of average daily concentration of methane in a gas-air mixture on return air from a lease №95, and also sizes of working areas of treating of a massif. By results of definition of the floor spaces of bands of treating and magnitude of variation of average daily concentration of methane taking into account its background value and daily quantity of air on lease return air coefficients of degasification of a coal seams of a band №4 through technological wells №1, №2, bands №5 through technological well №1 and radiuses of treating of a massif of 23 and 18 m accordingly are instituted; coefficients of an intensification of degasification of bands №4 and №5. As a result of hydrodynamic treating of a coal massif coal mining from the processed bands of bands №4 and №5 was augmented by 4 % and 5 % accordingly. Variability of hardness of coal in the processed bands has compounded: in a band №4 - 1,1 %, and in a band №5 - 6,8 % that is much less than 20 %. Efficiency of hydrodynamic affecting as a method of an intensification of degasification and decrease of gasdynamic activity in affected area of technological wells is erected. Coal-face works are spent without signs of the gasdynamic effects.
