摘要
本文以汾西矿业集团公司宜兴煤业公司1200工作面施工切眼为例,详细介绍了巷道施工切眼及支护方法。实践证明此方法支护的大断面巷道,可以承受巷道顶板和两帮的压力,保证液压支架等设备顺利安装。
In this paper, the roadway construction cutting and supporting methods are introduced in detail with the example of 1200 face construction cutting in Yixing Coal Industry Co., LTD. of Fenxi Mining Group. The practice proves that the large-section roadway supported by this method can withstand the pressure of roadway roof and the stress of two sides, and ensure the smooth installation of hydraulic support and other equipment.
