摘要
结合漳村煤矿西部扩区进风立井井筒普通法施工条件和预计穿过1号和2号富水性强的砂岩裂隙含水层水文地质情况,进风立井井筒施工时采用了工作面探水预注浆掘进施工技术,取得了较好的效果,为类似条件下的立井过含水层防治水提供了经验。
Combined the conditions of ordinary construction and the conditions of aquifer hydrogeological which is expected to pass through the 1 and 2 strong water- rich sandstone with the western expansion area of Zhangcun Coal Mine Shaft,the tunneling construction technique of exploring water and pre- grouting are used when the air intake shaft construction,and good results are achieved,providing the experience under the similar conditions of the prevention and control of water for similar shaft through the aquifer.
