人工假顶工艺在近距离过巷掘进的应用

Application of Arti ficial False Roof Technology in Driving Through Roadway in Short Distance

为了保证近距离煤层巷道掘进施工安全,提高过巷段顶板稳定性,对2112巷过830轨道巷期间采取人工假顶的方法进行近距离顶板维护工艺。实际应用表明,该工艺有效保证了近距离巷道掘进顶板稳定性,保证了巷道施工安全,取得了显著成效。

In order to ensure the safety of tunneling in the short-distance coal seam and improve the stability of the roof in the section passing through the roadway,the artificial false roof method is adopted to maintain the short-distance roof in the period of 2112 roadway passing through 830 track roadway.The practical application shows that the technology effectively guarantees the roof stability of the short distance tunnel driving and the safety of the tunnel construction.
