摘　　要：安徽前常铁铜矿正在开展深部基建,亟需摸清深部主矿体的三维空间分布特征、优质资源富集情况以及各地质要素的影响情况。基于Surpac软件对研究区的资料进行系统整理,建立了前常铁铜矿深部巷道模型、断层模型、含水体模型和主矿体Ⅴ9、Ⅵ1的三维地质模型;使用距离幂次反比法对主矿体资源量进行了重新估算,分析了主矿体在不同中段的资源分布特征;主矿体高品位优质资源在-750 m水平以上较富集,-750 m水平以下品位较低但规模相对较大。从三维可视化角度分析了断层和含水体对采矿的影响,明确了断层和含水体的影响范围和重点防范区域。The deep infrastructure construction of Qianchang iron-copper deposit in Anhui Province is being carried out.It is urgent to find out the three-dimensional spatial distribution characteristics of the main ore body in the deep part,the enrichment of high-quality resources and the influence of various geological factors.The data of the study area has been organized systematically based on the Surpac software,so that Qianchang iron-copper deposit 3D geological models including deep mine opening model,fault model,water-bearing body model,and main ore bodies ofⅤ9 andⅥ1 can be established.The resources of main ore body were re-estimated with the inversed distance weighting method.The resource distribution characteristics of main ore body in different levels have been analyzed.High grade and high-quality resources in the main ore body are relatively enriched above the level of-750 m,but lower grade and larger resources in the main ore body are below the level of-750 m.The impact of faults and water-bearing bodies on mining has been analyzed from 3D visualization perspective,and their impact scope and key prevention areas have been identified.
