摘要
针对巷道顶板锚固支护在实际应用过程中存在的问题,结合巷道围岩结构特征对方案进行优化。基于FLAC3D数值模拟软件,发现优化后巷道在垂直方向上的位移分布和应力分布得到了显著改善。经过实践证明,优化后的方案能够对顶板沉降量进行有效控制,没有出现显著的顶板离层现象。
In view of the problems existing in the practical application of roadway roof anchoring support, the scheme is optimized according to the structural characteristics of roadway surrounding rock. Based on FLAC3 D numerical simulation software, it is found that the displacement distribution and stress distribution of the optimized roadway in the vertical direction have been significantly improved. It is proved by practice that the optimized scheme can effectively control the settlement of the roof, and there is no significant phenomenon of roof separation.
