摘要
结合某矿采用分段空场法开采,嗣后全尾砂胶结充填采空区的生产实际,利用FLAC-3D软件建立了三维数值模型并进行数值模拟计算,对充填前后采空区围岩应力、位移进行比较分析,揭示了嗣后全尾砂胶结充填对采空区稳定性的影响机理,对类似矿山采空区治理具有重要的指导意义。
One mine was explored with open-stope method and then the goaf was filled with cementedtailings only.The author built a three-dimensional numerical model with FLAC-3D for numerical simulationcalculation,compared andanalyzed the surrounding rock stress and the displacement of the goaf before and after the filling,and revealed the influence mechanism of the filling of cemented tailings only upon the stability of the goaf.It has important guiding significance for goaf treatment in similar mines.
