以漳村煤矿2302综采工作面为工程背景,利用FLAC数值模拟软件,对开切眼支护解除条件下围巷稳定性进行数值模拟研究,得到了切眼附近巷道的位移变化曲线及工作面动压超前和滞后影响范围。研究结果表明,开切眼支护解除有利于矿压管理,提高了煤矿的经济效益。
Taking the 2302 fully mechanized coal mining face of Zhangcun Coal Mine as the engineering background, the numerical simulation of the roadway stability under the condition of open-cut eye support was carried out by using FLAC numerical simulation software. The displacement curve and working face of the roadway near the cut eye were obtained. Dynamic pressure ahead and lag affected area. The results show that the open cut eye support is conducive to the relief pressure management and improve the economic efficiency of coal mines.
