摘　　要：在埃塞俄比亚Harvest金铜多金属矿项目的资源评价中使用Surpac三维建模软件建立了矿区的钻孔地质数据库、矿区地表模型、矿体实体模型、矿相分界面模型、矿体块体模型,应用距离幂次反比法进行了资源量估算,生成了项目资源评价的核心数据,并且在此基础上进行了露天采矿设计,高效快速地完成了项目的整体评估。In the evaluation of Harvest gold and copper polymetallic mine in Ethiopia,by using the three-dimensional modeling software Surpac,a geological database was established,a surface topo file was finished.Geological interpretations of the oxide,transition and supergene mineralization were completed based on lithological,mineralogical and alteration features logged in drill cores.Mineralization wireframes were generated and resource estimation by power inverse method was carried out.Based on all the data above an open-pit mining design was designed with efficiency,and the whole evaluation of the project was finished.
