断层带预支护与注浆修复的使用

Forepolling Fault Repair with the Use of Grouting

叙述了断层带中围岩破碎程度,为了实现冒顶巷道连采机掘进的安全、快速掘进与修复,指出针对"漏冒型"巷道采用了"撞楔法"进行超前预支护和构造"假顶"、化学注浆加固假顶、"锚网索+架棚"联合支护相结合的支护方式,完成在断层带破碎带中的掘进和顶板冒顶巷道修复。

Describes the extent of the fault zone rock crushing, in order to achieve the safe, rapid excavation and restoration in roof fall roadway, points out that support method combined with ＂ pile sinking method ＂ advance support and construction ＂off the top＂, chemical grouting off the top, ＂cable anchor ＋ shed＂ joint supporting is used for the ＂leakage risk-type＂ roadway to complete the excavation in fault fracture zone and repair in the roof fall roadway.
