摘　　要：针对深部大面积采空两软工作面的特殊地质情况,首先对冲击地压发生的机理做了力学分析,阐明了冲击地压发生的机理,在此基础上进行了研究。最后为了验证以上结论,进行了包括支承压力、钻屑法和微震监测在内的现场实测研究。Rock burst floor with widespread illustrated. The above pressure, the results of occurred in deep working faces in special geological condition of soft roof and mined-out area backward were analyzed, the mechanical mechanism were analysis agreed well with practical test, such as the distribution of abutment drilling bits and microseismic monitoring.
