| 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。 |

| Abstract: |
| 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 of Ⅴ9 and Ⅵ1 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. |
