以西山煤电集团西曲矿北三下组煤集中运煤巷的掘进为工程背景,运用FLAC~(3D)进行数值模拟,计算分析巷道在挑顶不同阶段巷道围岩的应力分布和塑性变形情况,从而提出巷道挑顶地段巷道支护的加固方案。
Based on the engineering background of coal concentrated coal roadway in Beisansanxia formation of Xichang Coal and Electricity Group, FLAC 3D was used to carry out numerical simulation to calculate and analyze the stress distribution and plastic deformation of roadway surrounding rock in different stages , So as to propose the reinforcement plan of roadway support in roadway roof top section.
