针对史山煤矿3#采区高应力软岩巷道,基于对围岩稳定性分类分析、理论分析和工程对比,确定了该软岩回采巷道的支护方案和参数。运用FLAC~(3D)对高应力软岩巷道的开挖与支护围岩变形进行了模拟分析,验证了锚喷网支护方式的有效性和合理性。
Aiming at the high stress and soft rock roadway in No.3 mining area of Shishan Mine, based on the classification analysis, theoretical analysis and engineering comparison of the surrounding rock stability, the support schemes and parameters of the soft roadway are determined. FLAC 3D is used to simulate the deformation of high stress soft rock roadway and surrounding rock deformation, and the validity and rationality of the anchoring method are verified.
