摘　　要：为了研究底板破坏特征及其分布规律,确定深部水平工作面回采后底板扰动破坏深度,防范开采过程中因底板突水造成的水灾事故,城郊煤矿在2703工作面回采期间,采用直流激电仪对工作面底板破坏深度进行监测,掌握了采前底板原岩的电性赋存状态和回采后的受影响岩层电性破坏状态,直观地获取了受回采影响破坏深度和范围。To study the failure characteristics and the distribution of the coal seam floor,determined the damage depth after stoping the working face,prevented the flood caused by inrush accident in the process of mining,in the process of mining 2703 working face in Chengjiao Coal Mine,DC resistance tester was used to monitor the damage depth of floor on working face,the electrical state of the coal seam floor before mining and the rock electrical damage state of the coal seam floor after coal wining were mastered,the depth and scope of the damage influenced by coal wining were obtained intuitively.
