斜井井筒过断层的探索实践

Exploration Practice of Inclined Mine Shaft Through Fault

龙煤集团七煤分公司新立煤矿目前正在进行四阶段2条井筒的延伸,1条为轨道下山,1条为回风下山。井田内部共有标志性断层:逆断层FD及正断层FE。轨道下山正处于过FD断层期间。FD断层落差约15 m,有严重破碎裂隙带。施工过程中注瑞米材料加固巷道轮廓线,架设U形钢支架施工。

Seven branch coal in Xinli coal mine of longmei group is currently conducting four-stage two shaft extension a to track down a back down the hill. Mine field within a total of iconic faults: FD and FE fault inverse fault. Track down the hill is in the FD during faults. FD fault throw around 15 m,there is a serious crush fracture zone.
