Low permeability gas outburst pre-drainage outburst elimination was the problem constrained rapid mining of roadway. Based on this problem, Zhanghang Mining Industry adopted deep hole pre-splitting blasting technology to increase the permeability of coal seam and the rate of gas extraction, pressure extraction gas area within limits was formed in coal body, which effectively prevented the coal and gas outburst, better solved the contradiction between coal seam outburst prevention and rapid mining in low permeability coal seam mining.
