摘要
运用FLAC^(3D)数值模拟软件,对不同断层角度、工作面推进距离、上下盘分别开采情况进行模拟,获得了各因素作用下的断层面应力值及位移量,结合断层滑移失稳的敏感性指标-断层面应力比,对比分析得出各因素对断层活化的影响机制。
With numerical simulation software FLAC^3D,we simulate different fault angles,working face advancing distance and hanging wall and footwall mining situation respectively. We obtained fault plane stress value and displacement under the action of various factors. Combined with the sensitive index of fault slippage and instability： the stress ratio of fault plane,we get influencing mechanism of various factors on fault activation.
