摘　　要：由于开采技术限制,新城金矿浅部充填体内散布多个矿石残柱,上盘靠近主断层区段存留大量高品位矿体。为了残矿回收有序进行,采用SURPAC软件对矿体进行精确圈定与资源动态评估。研究结果表明:矿房中点柱及未能开采的矿石占52.4%,而顶底柱则占了总量的47.6%。确定了后续残矿回收的主要对象为矿柱和上下盘矿体。Due to the limitation of mining technology,multiple ore residues are scattered in the shal⁃low filling body of the Xincheng Gold Mine,and a large number of high-grade ore bodies remain in the hanging wall near the main fault section.In order to recover the residual ore in an orderly manner,SUR⁃PAC software is used to accurately delineate the ore body and evaluate the dynamic resources.The results of the study showed that the point pillars and unmined ore in the mine accounted for 52.4%,while the top and bottom pillars accounted for 47.6%of the total.It is determined that the main objects of subsequent re⁃sidual ore recovery are ore pillars and upper and lower ore bodies.
