Subject of research - the process parameters of the hydrodynamic impact on steep coal seam. Research methods - based on experimental studies of mine use hydrodynamic method of action on coal seam k8 - "Kamenka" №95-1160 of workface, gassing process with the treated area after the action on the lower workface №95 and analytical calculations hydrodynamic performance determined action dynamic changes daily average concentration of methane in the output air stream from the area, and radius zones of intense gassing. By concentration of methane in the output air stream from areas the daily coal production and quantities supplied ventilation air decontamination areas determined by the coefficient of coal seam through hole technology №7, №8 and №9, radiuses zones of intense methane degassing and factors intensifying the seam. Established hydrodynamic impact of method action to intensify the decontamination and reduce gas-dynamic activity areas of coal seams in the area of technological boreholes. Cleaning of the bottom of the workface №95 held with no signs gas-dynamic phenomena. HYDRODYNAMIC IMPACT, TECHNOLOGICAL BOREHOLES, AVERAGE CONCENTRATIONS, DEFORMATION MASSIF, COEFFICIENT OF DEGASSING, COEFFICIENT OF INTENSIFICATION DEGASSING.
