The job purpose - improvement of parameters of a mode of degassing and decrease of gasdynamic activity of bench coals l7u- "Pugachevka" and k8 - "Kamenka" in a heel of overhand longwall. Methods of researches - analytical, mining experiment. On the basis of mining experimental researches of process hydrodynamic effect on bench coals l7u - "Pugachevka" and k8 - "Kamenka" level 1146 m through technological holes it is defined a time history of mean diurnal concentration of methane in steam-and-gas mixture and coefficients of degassing and intensification of degassing of a treated block. By quantity of the coal extracted from a hole radiuses desintegration of coal round a hole are defined and parameters of hydro-dynamic effect on a heel of overhand longwalls are installed: - Quantity of technological holes, pieces - 1; - Pression of process of effect, MPa - 5-6; - Quantity of the drawn coal from zone, % - 0,02; - Coefficient of degassing of treated zone - > 0,45; - Coefficient of intensification of degassing - 2,7. Support of mining operations in treated zones of coals seam l7u - "Pugachevka" and k8 - "Kamenka" implemented hydrodynamic impact without tags of a development of gasdynamic effects. HYDRODYNAMIC IMPACT, TECHNOLOGICAL HOLES, MEAN DIURNAL CONCENTRATION, DEGASSING COEFFICIENT, COEFFICIENT OF INTENSIFICATION OF DEGASSING.
