摘要
针对南阳煤矿3202巷道顶板两帮变形、底板底臌较严重的情况,通过FLAC 3D对巷道围岩应力、塑性区、位移量等参数进行模拟,并对比分析支护前后各参数的变化,得出一些有益的结论。
According to the serious situation of Top tray and Floor deformation in Nanyang coal mine 3202 tunnel.The parameters of surrounding rock stress,plastic zone,displacement and other parameters are simulated by FLAC 3D,and the changes in the parameters of support and unsupport are analysed.We have obtained some useful conclusions.
