深部矿井巷道支护优化设计

Optimum Design of Deep Mine Roadway Support

结合A矿工程实例,通过围岩移动变形监测与围岩松动圈测试两种手段,分析了A矿初始回采巷道支护方案中存在的不足,并在此基础上对初始方案开展优化设计并运用数值模拟软件对优化设计方案的效果展开对比分析,证实了其可行性,希望能为其它矿井深部巷道支护的顺利开展提供一定的借鉴与参考。

Combined with the engineering example of A Mine, with the means of surrounding rock movement and deformation mo- nitoring and surrounding rock loose circle test, this paper analyzes the deficiencies in the initial roadway support program of A Mine, and on this basis, carries out the design optimization of the initial program, compares and analyzes the effect of the optimum design of the program by using numerical simulation software, and confirms its feasibility, hoping to provide some reference for the smooth development of deep mine roadway support of other mines.
