摘要
数据模型是联结现实世界和计算机世界的桥梁，三维空间数据模型作为数字矿山的核心内容和基础，它反映了真实矿山中三维空间实体及其相互之间的联系，为三维空间数据组织和三维空间数据库模式设计提供基本的概念和方法。矿山三维模型研究是“数字矿山”的核心组成部分，是现代矿山信息化研究的热点和重点。本文基于Surpac的矿山计算机三维模型研究的过程，实现了地质数据库的建立，实体模型、品位块体模型的创建等，重点探讨了建模过程中地质数据库的设计、地质解译、矿体储量估算的方法与技术，为矿区成矿规律的研究和成矿预测提供了有效的技术手段，大大提高了矿产勘查的效率，为促进我国矿山信息化的建设和发展提供了便捷的途径。 关键词：三维模型；Surpac；矿山；钻孔数据

Adstract
Data model is the bridge which connects real world and computer world,and as core content and basis of the digital mine，3D spatial data model reflects 3D spatial entities of real mine and relations among of them.And it provided the concepts and methods of ogranization of 3D spatialdata and design of 3D spatial data base schema.Three-dimensional model of mines is an important part of digitalmine, and it is also a hotspot on the research of modern mines informatization. Study on Computer three-dimensional model of mines of the process based on Surpac,which including establishment of geological database, creation of solid model and grade block model etc. some methods and techniques used in geological database design, geological interp retation and ore - body reserves estimation, were particular discussed. Finally, a kind of effective method and means is put forward formetallogenic study and prognosis in mines, which greatly improve the efficiency ofmineral exploration, and also promote the informatization construction in mine.
Key words: three-dimensional model; Surpac; mine; borehole data
