In order to solve the problems of the drilling layout for preventing coal and gas outburst in Fengcheng mining area, using numerical simulation method to analysis the draining radius of the draining borehole, The law of stress and gas flowing around the draining boreholes was studied, meanwhile the draining radius were examined in site, the effective influence radius of draining borehole was determined in this mining area, the reasonable parameters and the important reference were provided for preventing local coal and gas outburst in the mine.
