The purpose of work is development of method of degassing and reduce gas-dynamic activity of coal seams l7в-"Pugachevka" and m3 "Tolstiy" at the top of the lava. Research methods and analysis, mining experiment. Based on the mining of experimental studies of the process of hydrodynamic impact on coal seam l7в -"Pugachevka" and m3 "Tolstiy" horizon 1026 m through the process well defined dynamics of changes of average daily concentration of methane in the gas mixture and the coefficients degassing and intensification of degassing the processed array. The number extracted from wells and gas regulatory factor coal seam degasification determined the radii of the disintegrated coal around the well and set the parameters of hydrodynamic impact: the number of production wells - 1 piece; the process pressure impact-3-5 MPa; the pressure in the well after a reset -0 MPa; time cycle-4-5 min; the coefficient of degassing the treated area > 0,45; the radius of the disintegrated coal 20m Mining in the treated areas of the coal seams l7в -"Pugachevka" and m3 "Tolstiy" hydrodynamic effect was realized without signs of outburst of coal and gas. HYDRODYNAMIC EFFECTS, PRODUCTION WELLS, THE AVERAGE CONCENTRATION, THE RATE OF DEGASSING.
