摘要
通过分析朔里煤矿629工作面开掘切眼的困难,提出了沿向斜轴部掘进放水巷,以此排放老空水。并对放水巷进行锚杆、锚索、网、钢带耦合支护,且局部采用注浆加固等综合支护技术。矿压观测结果表明,该方法应用效果良好。
Through analysing the difficulties of drilling cutting hole on 629 working face in Shuoli Coal Mine,a means of driving water- release roadway in the direction of syncline axis was put forward to discharge the goaf water in this paper. Coupling supporting technolo- gy of bolting with mesh and anchor cable and steel belt was implemented in water-release roadway. Comprehensive supporting technology such as grouting reinforcement was also applied in some areas. The results of mine pressure observation show that, the effects of this method are good.
