摘　　要：本文针对晋北煤业5-103工作面过空巷时巷道围岩变形特征和围岩变形机理进行了分析,得到支护强度大于3.65 MPa是安全充填作业的保障,经过现场充填和工作面调斜方案,控制了巷道围岩的变形,提高了工作面的推进速率。This paper analyzes the deformation characteristics and deformation mechanism of surrounding rock of 5-103 working face crossing gob of Jinbei coal industry.It is concluded that the filling operation is safe when the support strength is greater than 3.65MPa.The deformation of surrounding rock of roadway is controlled and the advancing speed of working face is improved by filling on site and adjusting inclination of working face.

关 键 词：工作面过空巷 充填作业 工作面调斜
