摘　　要：矿山三维立体模型的建立是矿山数字化的基础。本文系统收集了阳山金矿安坝矿段勘探线剖面图28条,编录了钻孔数据106个,分析了31446个钻孔采样结果,建立了钻孔数据库;应用3D Mine矿业工程软件构建了地形模型和矿体模型;对于三维建模的一般技术路线进行了初步归纳;建立了安坝矿段三维实体模型;并对矿体形态进行了分析,从而探讨了阳山金矿区的构造控矿规律,解释了矿体形态可能的形成原因,以期为阳山的深入找矿工作提供一定的理论依据。3D modeling of orebody morphology is the base of digitalization of a mine. We conducted such work to the Anba section of the Yangshan gold deposit in Gansu Province. Totally data of 28 exploration lines, 106 drill holes and 31446 borehole samples were collected and analyzed, yielding a database. Then we used the software 3D Mine in combination with Digital Elevation Model （DEM） to constructed the models of topography and orebody morphology. We summarized the 3D modeling technical process, established the 3D model for the Anba section of the deposit, and analyzed orebody shapes. We also explored the rules of structural control on orebodies, and interpreted the possible reasons for generation of orebody shapes, which can pro- vide theoretical basis for further exploration in the Yangshan mine area.
