摘　　要：结合江西省香炉山钨矿的残矿回收工程实践,利用有限元数值分析软件3D-δ建立三维数值模型,对该矿复杂采空区条件下残矿回收与采空区稳定性进行了数值模拟,揭示了残采过程中矿柱及采空区的应力分布规律和位移变形趋势,验证和评价了传统经验方法判断结果的可靠性,模拟结果对矿山安全回收残矿、矿柱加固处理工作有重要的指导意义。Based on engineering practice in Xianglushan Tungsten Mine Jiangxi,the stoping of remnant ores and stability for complicated Mine area were analyzed by use of 3D-δ.the stress distribution and displacement trend were revealed,and the reliability of results by the empirical methods was verified and evaluated.The results were important to stoping of remnant ores safety and reinforcing measures reasonablely for pillar.
