摘　　要：针对大众煤矿突出煤层的情况,采用穿层钻孔和顺层钻孔相结合预抽煤层瓦斯,同时采用水力冲孔消突及增透,并通过增加封孔段长度提高封孔质量,能够有效消除突出煤层采掘工作面的瓦斯灾害,为大众煤矿的安全生产提供了重要保障。Methods of borehole drilling through and along rock mass were utilized for predraining gas in outburst coal seams at Dazhong Coal Mine;hydraulic flushing in holes to remove outburst stress and increase permeability and increasing the length of sealing section of boreholes to improve the sealing quality could both effectively mitigate the threats from gas accidents at mining and driving work faces in outburst coal seams,which provide critical safety guard for mining production of Dazhong Coal Mine.
