摘 要:基于马脊梁矿2117巷掘进期间受地质构造影响,巷道掘进至315~370 m段多处出现局部冒漏现象,采用传统锚杆(索)、工字钢棚联合支护效果差的问题,通过技术研究,决定对局部冒漏区采取“锚索梯形棚+挡矸支架+人工假顶”联合支护措施。通过实际效果来看,支护优化后大大提高了冒漏区围岩整体稳定性,控制了顶板蠕动变形现象,取得了显著应用成效。Based on the influence of geological structure during the excavation of 2117 roadway in Ma Zhiliang Mine,there are many local leakage phenomena in 315~370 m section of the roadway,and the joint support effect of using traditional anchor rods(ropes)and I-beam sheds is poor,so we decided to optimize the support of local leakage area by adopting the joint support measure of"Anchor trapezoidal shed+gangue blocking bracket+artificial false top"through the technical research.Through the technical research,it is decided to adopt"anchor cable trapezoidal shed+block gang bracket+artificial false roof'joint support measures for the support optimisation of local leakage area.
