摘　　要：应用三维地质建模软件能够全方位展示矿体形态及品位分布特征,便于统计勘查区段的品位及资源量。以澳大利亚西部某铅锌矿为例,基于Micromine软件,构建了矿体地质数据库,圈定了矿化域范围,采用普通克里金法分别对Pb、Zn品位进行了估算,构建了矿体品位分布模型。研究表明:矿化域内Pb、Zn平均品位相当,但Pb富集程度高,矿化域南区东侧具备进一步勘查的潜力。3 D geological modeling software is helpful to display the ore-body shape and grade distribution characteristics,and calculate the grade and resource reserves of exploration area. Taking a Pb-Zn deposit in Western Australia as the study example,based on Micromine software,the ore-body geological database is established,the mineralized area is delineated,the grades of Pb and Zn are calculated respectively by using ordinary kriging method and the ore grade distribution model is established. The study results show that the grade of Pb is basically consistent with one of Zn in the mineralized area,but the enrichment degree of Pb is higher than Zn,the prospecting potential of the southeastern part of the mineralized area is good.
