根据伏牛山煤矿11条巷道和81个破坏点的矿压观测资料,分析得出该矿地压大的主要原因是构造应力的影响。并总结了针对松软岩层中的巷道采取砌璇加木砖,对地质构造复杂处的巷道采用“U”型钢可缩性支架支护的成功经验。
According to the rock pressure observation data of 11 tunnels and 81 failure points in Funiushan Mine, it is concluded that the main reason of the large underground pressure is the influence of tectonic stress. The author also summarizes the successful experience of using “Xuan” steel scaffolding support for tunnels in soft rock formations and adopting “Xuanzuan plus wood bricks” for tunnels with complex geological formations.
