摘要
针对西山煤电集团西曲煤矿北三下组集中运煤巷道掘进出现应力较大的问题,按照工程实际情况,采用FLAC3D软件进行数值模拟,计算分析了巷道围岩在不同掘进程度的应力分布和塑性变形,提出了巷道交叉时的支护方案。
Aiming at the problem of high stress in the centralized coal roadway excavation of North Third Lower Team of Xiqu Coal Mine of Xishan Coal Electricity Group Co.,Ltd.,according to the actual project conditions,the subject makes use of FLAC3 D software for numerical simulation to calculate and analyze the stress distribution and plastic deformation of roadway surrounding rock at different excavation progress,and proposes a support scheme in the case of staggered roadways.
