Surpac软件在巴彦乌拉铀矿床三维地质建模中的应用

摘要

三维地质建模能够对大量复杂的地质体进行直观显示和表达,有利于展现地质体的内部形态特征,便于成矿规律的研究.以二连盆地巴彦乌拉砂岩型铀矿床为研究对象,对该地区相关地质资料进行整理和收集,对钻孔数据进行信息化处理.借助三维矿业软件Surpac,先后建立了巴彦乌拉铀矿床地质数据库、地质体实体模型以及块体模型和品位模型.在此基础上总结了构建地质体三维模型的原理方法,并探讨了三维地质建模可视化的应用.%The 3D geological modeling can visually display and express a large number of complex geological bodies,Which it is advantageous to show the internal shape characteristics of the geological body,and study on the metallogenic regularity.This paper taking Bayanwula uranium deposits as the research object,related geological materials in the area are Collected and carried on the information processing.With the help of large international mining software Surpac,constructed the geological database of Bayanwula uranium deposits,geological entity model,block model and grade model.On the basis of this,the principle and method of constructing 3 D visualization model of geological bodies are summarized,and discusses the application of 3D Modeling Visualization in various aspects.
