摘要
由于煤矿巷道的地质条件复杂多变,为了对井巷围岩的稳定性做出正确评价,借助ANSYS软件,对支护后采煤巷道进行数值模拟,通过对巷道围岩和围岩的混凝土喷层应力状态进行分析研究,来验证支护手段和支护参数是否具有合理性,从而对围岩稳定性做出正确的评价。
Due to the changeful and complicated geological conditions of coal mine roadway, in order to make correct evaluation to the stability of surrounding rock of mine, with the help of ANSYS software, numerical simulation was carried out on the support mining roadway, through the analysis study of surrounding rock of roadway and the surrounding rock stress state of concrete spray layer state, which validated support means and supporting parameters whether reasonable or not, so as to evaluate the stability of surrounding rock correctly.
