Methods of researches - analytical and mine experimental. On the basis of analytical and mine experimental researches of process of a gas emission at hydrodynamic affecting on a bench coal k8 - "Kamenka" of a lease №95 after its conducting in bottom of the bar №6 completed by the shield aggregate, has been instituted a time history of average daily concentration of methane in a gas-air mixture on return air from longwall №95, and also sizes of bands of treating of a massif. By results of definition of the floor space of a band of treating and magnitude of variation of average daily concentration of methane taking into account its background value and daily quantity of air on return air from longwall the coefficient of degasification of a bench coal of a bar № 6 through technological wells №1 and №2 - 0,56, radius of treating of a massif of 27 m and coefficient of an intensification of degasification of a bar №6 - 1,29 is instituted. As a result of hydrodynamic treating of a carbonic massif coal mining from the treated band of a bar №6 was augmented by 51 %. 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 lead without indications of gasdynamic appearances.
