摘要
针对柿竹园多金属矿空区处理现状,采用FLAC3D软件对崩落放顶过程进行了数值模拟分析,模拟结果反映了采空区范围的地压活动规律及矿柱稳定性变化情况,对同类多空区矿山开采具有积极的指导意义。
For the status of mined-out areas of Shizhuyuan polymetallic ore, applying FLAC^3D numerical modeling analyzed the process of caving mining,the results reflect the ground pressure activity patterns and the change of pillars stability, the study has the positive guiding sense to similar mine mining.
