摘　　要：根据济宁二号煤矿孤岛面综放顺槽布置的具体条件,采用现场实测的方法,对综放回采巷道在回采过程中的巷道变形进行了实测研究,结合钻屑法监测,得出了综放顺槽发生冲击危险的范围,为今后冲击地压的防治提供基础资料,进而为完善回采巷道设计提供科学依据。According to the condition arrangement of fully mechanized roadway of isolated face in Jining No.2 Coal Mine, field experiments were adopted and roachway deformation during the retreating time with the site- measure method was carried out. Then the range of the rock burst hazard of roadway was obtained combined with the method of drilling bits. It provides some fundamental documents for the prevention of the rock - burst and the scientific base to improve the roadway designing method.
