本文利用充分变形离散单元法对平六矿松软破碎围岩回采巷道锚网支护参数进行数值模拟 ,详细分析了不同锚网支护参数对控制围岩变形的影响规律。其研究结果对控制围岩应力和变形稳定所需的最佳锚网支护参数具有较好的指导作用
In this paper, fully deformed discrete element method is used to simulate the bolting and meshing parameters of soft rock roadway in Ping 6 Mine. The influence of different bolting parameters on the deformation of surrounding rock is analyzed in detail. The results of this study have a good guiding role in controlling the optimal parameters of bolting support for surrounding rock stress and deformation stability
