The subject of research- parameters of method of hydrodynamic affecting on effective degasification of a bench coal. Methods of studies - on the basis of analytical and mine experimental researches of process of hydrodynamic affecting on a bench coal m3 - "Tolstuj" a lease №42 and process of a gas emission of the treated band after its conducting in bottom of the bar №5 completed by the shield aggregate, has been instituted a change dynamics of average daily concentration of methane in a gas-air mixture on return air from longwall, 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 change of average daily concentration of methane taking into account its background value and daily quantity of air on longwall return air the coefficient of degasification of a bench coal of a bar №5 through technological well № 1-0,53, radius of treating of a massif of 22,9 m and coefficient of an intensification of degasification of a bar №5-3,6 is instituted. 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 in bottom of a bar №5 and baring of a bench coal by an intermediate crosscut №6 are lead without indications of gasdynamic appearances.
