分析了大隆煤矿S11201工作面的瓦斯来源及采空区瓦斯分布情况，得出因受工作面采动卸压影响，下邻近层瓦斯大量涌向S11201工作面采空区，是造成工作面瓦斯涌出异常的主要原因。针对性提出“回风巷迎向斜交钻孔方法”抽采采空区裂隙带卸压瓦斯，取得了理想的抽放效果，确保了工作面的安全回采。

This paper analyzed the gas source in S1 1201 working face and the gas distribution in its gob in Dalong Coal Mine, it came to the conclusions that the large gas emission from the lower adjacent coal seam to S11201 working face is the main cause of abnormal gas emission in this face. For this reason, the technology of gas drainage from the cracked zone in the gob by“oblique cross boreholes in air return gateway” was put forward, the use of this technology got an ideal drainage effect and ensured the safe mining of this working face.
