摘　　要：为保证某矿山安全、高效开采,根据该矿山矿体开采技术条件及矿岩物理力学性质,应用Flac^(3D)软件分别对4种开采方案不同采场结构参数进行数值模拟分析,结果表明:开采1235 m标高以上矿体时,采用采场矿房长40 m,矿房间留2 m连续间柱,顶、底柱2 m的采场结构参数效果最优;开采1235 m标高以下矿体时,采用充填采矿法最优;符合矿山“安全、高效、低成本、低贫损”的开采理念。研究成果可为该矿山的安全生产提供理论性指导。In order to ensure safe and efficient mining,according to the mining technical conditions of the ore body and the physical and mechanical properties of the ore rock,the Flac^(3D)software was used to carry out numerical simulation analysis on the different stope structure parameters of 4 mining plans.The results show that when mining ore bodies above the elevation of 1235 m,the offect is the best with stope structure parameters as fallows:the length of the stope is 40 m,the continuous pillar of 2 m is left between ore rooms,and the top and bottom pillars are 2 m;when mining the ore body below the elevation of 1235 m,the backfill mining method is the best;the mining concept of"safe,efficient,low-cost,low-loss"is met.The research achievement provides theoretical guidance for the safe production of the mine.
