摘要
基于ANSYS有限元分析软件,针对某铁矿的赋存条件、试验采场位置以及开挖的影响范围,建立了三维计算模型,设计了5个模拟方案,进行了不同条件下的采场结构参数和回采顺序的数值模拟,分析了矿山开采施工对围岩稳定性的影响程度,其计算方法和结果可供相关人员参考。
Based on finite element analysis software ANSYS,a three-dimensional calculation model has been established in terms of occurrence conditions,position of test stope as well as excavation effect range of an iron mine.Five simulation schemes are designed.Stope structure parameters and stoping sequence under different conditions are simulated by numerical method.The effects of mine mining construction on wall rock stability are analyzed.The calculation methods and results are given as references for relevant personnel.
