摘要: 青岗坪煤矿42102首采综放面运输平巷在掘进过程中遇到走向大正断层,为了减弱该断层对首采综放面回采的影响,采用了上、下平巷钻探及工作面推进过程中跟踪观测相结合的方法,准确控制了断层产状,工作面沿断层走向直接推过断层,并采用分装分运的方法保证了煤质,提高了资源回收率,取得了良好技术经济效果。同时,打破了工作面过断层的传统方法,具有较好的推广应用价值。

Abstract: There is a huge strike fault in the tunnel of 42102 work face which is the first exploitation of Qinggangping coal mine. In order to minimize the influence of this fault during mining, it uses boring method in the two tunnels of 42102 work face, compromised with the actual observation in mining. It can control the occurrence of fault accurately, and also can increase resource recovery rate with the favourable technical-economic effect. Meanwhile, it beaks the traditional method of passing fault, and is worthy to application and dissemination.
Key words: fault, head, boring, working face, coal property
