摘要
运用ANSYS软件,分析大安山煤矿矿区应力场分布特征,考虑断层和褶曲,模拟出二维地应力场。得出:(1)褶曲和断层对剪切应力影响明显;(2)最大主应力大小分布的总体趋势是随深度的增加而增大;并且单位深度增加的最大主应力值逐渐增大;(3)模拟结果和实测结果有较好吻合,说明数值模拟对实际工程有一定参考价值。特别是对深部未开采煤层预测地应力能起到重要作用。
In order to ravel distributive characteristic of stress field of Daanshan colliery,considering faultage and fold,with ANSYS software,two-dimensional geo-stress field has been simulated.The results show：（1）Shear-stress is deeply affected by faultage and fold;（2）Tendency of major principal stress distribution is increasing with the depth and per unit of depth;（3）Simulation results are well coincide with observation results and it has a reference value to engineering,especially to deeply coal seam unmined geo-stress forecast
