摘要
贵州省黔西南州地属山区,矿区主要地质构造为褶皱、断裂,次生断裂发育,矿体顶板较软弱,巷道维护困难。准确预测巷道围岩应力分布及变形是此类矿山安全生产的一个难题。利用3DMine模型与数值模拟软件Phase2耦合后进行数值分析,结果能准确反应巷道围岩应力分布及变形情况,对解决此类复杂地质矿山的安全生产具有重要意义。
Guizhou Qianxinan to a mountain, the main mine geological structure is folded, fracture,secondary faults, ore foof relatively weak, the roadway maintenance is difficult. Accurately predicting the stress distribution and deformation of surrounding rock is a problem of such mine production safety.Using of 3DMine model and numerical simulation software Phase2 coupling to numerical analysis, the results can accurately reflect the surrounding rock stress distribution and deformation, which is important to solve these complex geological mine production safety.
