摘　　要：随着二维GIS和计算机技术的日益成熟,三维地质建模成为了一个研究热点,文章从三维地质建模概念出发,利用iExploration-EM软件,探讨了基于钻孔数据的三维地质建模及可视化的一般过程:包括西藏尼木岗讲地区斑岩型铜矿地质数据库的建立、实体模型的创建,其中实体模型的创建是文章的重点。本文所创建的实体模型为矿体实体模型,主要介绍矿体实体模型创建方法及过程和成果等方面的内容。三维建模成果展示图直观的展示了矿体的赋存状态和矿产规模,为矿产储量计算奠定了基础,对于可行性方案的确定,提高矿产的管理和工作效率的提高有着重要的意义。This paper is based on three dimensional geological modeling rules,General process of 3D geological modeling and visualization is discussed based on modeling the geological database and the 3D model of orebody from its concept,including establishment of the geological database and the 3D model of orebody.all of them are realized by iExplorationEM software.The 3D model of orebody creation is the focus of the article.The 3D model of orebody includes Strata the 3D model of ore body,Ore body the 3D model of orebody and rock solid model.This paper mainly talks about the 3D model of orebody of the creating method and process and results etc.The three-dimensional visualization of the deposit in this area is realized,and the spatial information of the ore body is accurately expressed,which provides an effective basis for the mining and dynamic production management of the deposit.
