Methods of research - analytical, mine experimental researches. On the basis of mine experimental researches of process of hydrodynamic affecting on a bench coal l7top - "Pugachevka - the east" mountains. 1146 m through technological wells in bottom of longwall №7 on SD(station distance) 59+6 and №2 SD46, №3 SD51+3, №4 SD54+6 in longwall top has been instituted a time history of average daily concentration of methane in a gas-air mixture before hydrodynamic affecting on hills, and also sizes of bands of its treating. By results of definition of the floor spaces of bands of treating and variation of average daily concentration of methane taking into account background and daily quantity of air on return air from a lease №65 coefficients of degasification of a bench coal in bands of its treating through technological wells №2, №3, №4 and №7 - 0,67 are instituted at the floor space of treating 5666 м2 and coefficient of an intensification of degasification 1,5. 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. HYDRODYNAMIC AFFECTING, TECHNOLOGICAL WELLS, AVERAGE DAILY CONCENTRATION, STRAIN MASSIF, DEGASIFICATION COEFFICIENT, COEFFICIENT DEGASIFICATION INTENSIFICATION.
