The Purpose of the work is conducting the work on determination and concrete definition parameters of a way of an intensification of inflow of gas in degassing wells, definition of optimum radius of drainage methane and increasing of safety of works. The methods of researches is analytical, statistical, mine, experimental. In process of the conducting the experimental work on study of the processes gas emission from coal seams k8 -"Kamenka-vostok" of horizon. 1146 m of Name mine. F.E. Dzerzhinskogo at degassing and decrease outburst hazard by hydrodynamic influence in lower part of longwall № 95, fulfilled by the panel board unit it has been established: - by results of gauging of daily average concentration of gas in an air-gas mix in development taking into account the background the сcoefficient of decontamination of massif after its processing through technological wells which is equal is defined: for well of №1 strips №2 and wells of №1 and №2 strips №3 - 0,48 and 0,53 accordingly at necessary k anymore or equal 0,45; - the exit of coal has made of the processed wells: on well of №1 strips №2, well of №1 strips №3, and well of №2 strips 3-10,0 t, 6,3 t and 7,0 т accordingly at necessary quantity of its exit of M anymore or equal 6,02 t.; - rational parameters of drilling of technological wells are established; - a distance between points of crossing of wells with a coal seam on falling-30 m; - a distance between wells on prodeleting; - efficiency of hydrodynamic influence as way of degassing and outburst hazard decrease in a zone of influence of technological wells is established.
