3022巷断层冒漏区顶板支护技术应用

Application of Roof Support Technology in Fault Leakage Area of the 3022 Roadway

为了防止店坪煤矿3022巷过F4断层时顶板冒漏区范围扩大,对冒漏区施工密集锚索、注浆加固人工假顶以及密集钢棚等联合支护,防止了塑性破坏区范围扩大,巷道在后期掘进中冒漏现象得到了有效控制,取得了显著应用成效。

In order to prevent the expansion of the roof leakage area when the 3022 roadway of Dianping Coal Mine passes through the F4 fault,construction of dense anchor cables,grouting reinforcement of artificial false roofs,dense steel sheds and so on are combined to support the leakage area,preventing the expansion of the plastic damage area.The leakage phenomenon of the roadway is effectively controlled in the later excavation,and significant application results are achieved.
