矿山三维可视化建模技术己经在国外的矿山设计和生产中发挥了巨大作用。但是，目前这种技术在国内的设计院所和矿山很少被采用。通过对国外一些矿业软件在国内金属矿山的应用情况进行分析和比较，本文以陕西银母寺铅锌矿为例，研究应用Surpac矿业软件在国内金属矿山构建矿床三维模型的方法。 本文从地层及构造、矿体特征、矿石特征、近矿围岩蚀变与矿床成因几个方面对银母寺铅锌矿床地质特征进行了总结分析。在此基础上，根据Surpac软件的建模流程构建了银母寺铅锌矿山三维矿床模型，主要包括地质数据库、实体模型（矿体模型、断层面模型、地形模型、地层面模型，巷道模型）和品位模型。地质数据库方面，按照分析表结构——建立空数据库——录入数据的流程进行构建。实体模型方面，通过研究和分析实体模型的构建原理和流程，提出了构建银母寺铅锌矿床地质体实体模型的具体方法即剖面线法以及构建复杂地质体实体模型（复杂、不规则地质体、分支复合现象、封闭与尖灭现象的处理）的几点经验。品位模型方面，在矿体实体模型的基础上，提出了构建品位模型的方案，采用最近距离法为块体模型估值，构建了银母寺铅锌矿床Pb、Zn、Cu的品位模型。 银母寺铅锌矿床三维模型将地表和深部的地质及探采工程信息直观、形象地进行展示，不仅可以指导该矿山设计、生产管理，还可以基于模型研究矿床成矿规律、进行深部成矿预测。地质数据库具有在三维空间显示地质数据、地质解译和剖面品位计算、基本地质统计与分析、线性回归分析、线文件剖面输出等功能。实体模型在研究矿床成矿规律、图形展示及探矿工程设计方面都具有重要的作用。品位模型具有查询块体属性、按属性为模型着色、自动进行资源储量的报告等功能。在模型构建的过程中，将所遇到的问题进行归纳分析，总结出了一套基于Surpac的铅锌矿山三维矿床模型构建方法。

Three-dimensional visualization modeling technology has been widely used in the mines design and production abroad, but rarely used in domestic design institute and the mines. Compared with some foreign mining software in the domestic metal mines, this article take the Shaanxi Yinmusi lead-zinc deposit as an example，research on how to use Surpac software in the domestic metal mine deposits’ construction of 3-dimensions visualization model. This article from the stratum and the structure, the ore body characteristic, the ore characteristic, near ore l-rock alteration and ore deposit origin several aspects has carried on the summary analysis to the Yinmusi lead-zinc deposit geological feature. On this basis, in accordance with Surpac software's modelling flow, has constructed the 3-dimensions models for Yinmusi lead-zinc deposit, including geological database, the solid model (orebody model, the fault plane model, terrain model, the stratum model, the tunnel model.) and the grade model. Geological database, in accordance with the analysis of table structure, the establishment of the database space, the data entry process for construction. The solid model, through research and analysis solid model of principles and processes, constructing the solid model of Yinmusi lead-zinc deposit, and summarying some experiences on how to build complex geological model of entities (complex, irregular geological body, branch of the phenomenon, and pinch closed the deal with the phenomenon). The grade model aspect, in the orebody model's foundation, proposed the construction personal status model's plan, uses the point blank range law for the block phantom estimate value, has constructed the Pb, Zn and Cu grade model of Yinmusi lead-zinc deposit. The 3-dimensions models for Yinmusi lead-zinc deposit will display the image of surface and deep geological exploration and mining projects visual information, not only can guide the mine design, production management, but also based on the model for further research. The geological database has many functions, such as in the three-dimensional space demonstration geological data, the geological interpretation and the section plane personal status computation, the basic geological statistics and the analysis, the linear regression analysis, line profile document output and so on. Solid models on deposit, graphics display and prospecting project design have an important role. The grade model has the inquiry block body attribute, according to the attribute for the model coloration, to carry on resources reserves functions automatically and so on. In the model construction's complete process, the problems encountered by summarizing analysis, summed up a set method to constructe 3-dimensions lead-zinc mine deposit models based on Surpac.
