Abstract: According to the low permeability of the steep inclined seam, long gas pre-drainage time, high construction engineering work of the local outburst preven tion measures for the outburst prevention gateway driving face, high safety threatener and the low production efficiency of Fengchun Mine, the oblique dip automatic pr essure releasing and comprehensive drainage technology was provided to increase the gas drainage rate of the steep inclined single serious outburst seam and to impr ove the coal and gas outburst prevention and control technology.The application results of the technology to No.S1862 coal mining face in Fengchun Mine showed that after the bench mining, the pressure released protected scope of the underneath seam reached 7.60 ~ 9.97 m, the advancing speed of each bench in the coal mining fa ce was 3~ 19 m/ (8 h) and the average advancing speed was 7 m/ (8 h) .Therefore, the auto pressure releasing and automatic comprehensive drainage technology coul d effectively reduce the coal and gas outburst dangers and could obviously reduce the gas emission quantity during the coal mining period.The automatic pressure rele asing principle of the oblique tip heading and bench mining method could ensure the front seam of the mining face not in a danger of coal and gas outburst.
