摘　　要：文章利用Vulcan和Datamine三维可视化软件建立了虎头崖铅锌多金属矿床矿体的三维实体模型、块体模型及地层三维实体模型;运用地质统计学方法分析了虎头崖矿区67线以东和117线以西矿体的Pb,Zn品位空间变化结构,得出搜索椭球体,实现了虎头崖铅锌多金属矿床矿体、地层形态和铅锌品位变化形态的空间分布展示;结合三维建模结果和铅锌矿体空间变化结构,总结出矿体空间分布规律,并用三维可视化软件对矿体分布规律进行显示,指导隐伏矿体的预测,寻找有利的找矿部位。Three-dimensional solid models and block models of the ore bodies and the stratums in the Hutouya Pb Zn polymetallic deposit are established by using Vulcan and Datamine software. The spatial variation of the ore bodies＇ Pb and Zn grade in the east of the exploration line 67 and the west of the exploration line 117 are analyzed by geostatistic method and a search ellipsoid is obtained and spatial variation of ore bodies＇ morphology and ore grade is displayed. The spatial distribution model of ore bodies is summarized to guide ore prediction, or location of possible blind ore bodies.
