基于Surpac软件的王家村金矿化体三维建模研究与应用

山东省平邑县王家村金矿化体赋存于寒武纪地层与顺层侵入的二长斑岩接触部位，为鲁西铜石地区又一新类型金矿，找矿前景良好。传统方法估算矿化体的资源量效果不佳，该文借助Surpac软件工具，在研究王家村金矿（化）体地质特征的基础上，根据矿床以往的地质勘查工程资料,首次建立了王家村矿床地质数据库,构建了矿区的三维可视化地质模型,模型形象直观的展现了矿区地形地貌、矿体展布位置及形态。并应用距离幂次反比法对矿体进行了资源量估算。用此软件进行资源量估算简便且准确，可以根据不同品位实现资源量的动态统计分析。

Research and Application of 3D Modeling in Wangjiacun Gold Mineralization Body Based on Surpac Software

Gold mineralization body in Wangjiacun of Pingyi county in Shandong Province lies in contact region of Cambrian strata and monzonite which intruded along the strata. It is a new type gold deposit with good ore prospects in western Shandong. The evaluation effect is not good by using traditional method to estimate the resources of mineralized body. On the basis of studying geological characteristics of Wangjiacun gold mineralization body, according to previous geological survey data, geological database of Wangjiacun gold deposit has been set up for the first time, and threedimensional visualization geological model by means of Surpac software has been constructed. The model visually shows the mining topography, distribution location and shape of the ore bodies. Reserves have been estimated by inverse distance weighted method. The resource estimation based on Surpac software is more simple and accurate. Dynamic statistics of the resource reserves can be realized according to different grade.
