摘要
为了解决任楼矿深井高应力三软煤层巷道围岩变形量大、煤岩皆松软易破碎的难题,通过理论分析、FLAC^(3D)数值模拟和现场矿压监测相结合的方法,分析了高应力三软煤层巷道围岩变形机理,并提出了新的锚网索支护技术方案。
In order to solve the problem of the surrounding rock large deformation and soft and easily broken of coal rock in Renlou coal mine deep high stress three soft coal seam roadway,the experiment of theoretical analysis, FLAC3D numerical simulation and mine pressure monitoring were applied to analyze the surrounding rock deformation mechanism of the high stress and three soft coal seam roadway, put forward a new anchor wire rope supporting technology solution.
