3016运输巷支护参数优化研究及应用

Research and Application of Support Parameters Optimization of the 3016 Transport Roadway

为增强高地应力下巷道围岩的稳定性,以大西矿3016运输巷为工程背景,采用数值模拟对比原有巷道支护方案和不同方案支护下的巷道围岩的变形特性,提出巷道锚杆索支护的优化方案。通过在巷道中展开原有支护方案和优化方案的实际支护对比发现,采用优化后支护参数的巷道受掘进扰动的影响降低,围岩变形量明显减小。

In order to enhance the stability of roadway surrounding rock under high ground stress,taking the 3016 transportation roadway of Daxi Mine as the engineering background,the deformation characteristics of roadway surrounding rock under the original roadway support scheme and different support schemes are compared by numerical simulation,and the optimization scheme of roadway bolt support is proposed.Through the actual support comparison between the original support scheme and the optimized scheme in the roadway,it is found that the influence of excavation disturbance on the roadway with optimized support parameters is reduced,and the deformation of surrounding rock is significantly reduced.
