摘　　要：为解决西曲矿综采面过构造(断层)期间因炮眼布置多、爆破效果不明显,导致推进速度慢、影响安全高效回采等难题,拟定采用中深孔爆破技术,并进行了工艺改进;应用取得了良好效果,保证了工作面的安全高效回采,此技术对该矿其他工作面过构造具有借鉴意义。In order to solve the problems of slow advancement speed and impact on safe and efficient mining due to the excessive arrangement of blast holes and unclear blasting effects during the fully mechanized mining face crossing structure(fault)in Xiqu Colliery,it is proposed to adopt medium length hole blasting technology and make process improvements in the paper.The application has achieved good results,which ensures the safe and efficient mining of the working face and has reference significance for the structure of other working faces in the mine.

关 键 词：综采工作面 过断层构造 中深孔爆破技术 水砂袋封孔 炮眼布置
