【摘要】：矿产勘查中的三维可视化建模技术已经在国外的矿山勘查、生产中发挥了巨大作用,但是目前这种三维建模技术在国内的地质勘查单位中很少被利用。本文以四川木里县菜园子金矿为例,综合研究Surpac软件在矿山勘查过程中的三维地质建模技术,主要研究工作及成果如下:(1)在对收集到的菜园子金矿床资料进行整理和分析的基础上,建立了菜园子金矿床地质数据库,实现了钻孔信息可视化。(2)运用Surpac三维建模软件建立起了菜园子金矿矿区的地表及金矿体的三维实体模型,实现了矿床的三维可视化。三维可视化建模可以完整准确地表达出钻孔与金矿体的空间位置关系,为矿山进行科学的生产进度计划编制提供基础与依据。(3)运用地质统计学原理对钻孔样品数据进行了组合分析,根据组合样的统计特征,对实验变异函数进行了拟合,建立了合理的变异函数模型,构建起了金矿体的块体模型。(4)以所建立的块体模型为基础,采用距离幂次反比法对菜园子金矿床Ⅱ矿体的金资源量进行了估算及分布规律展示。通过Surpac软件对菜园子金矿床可视化三维模型的建立,矿体的形态以及储量分布能够较为清楚的掌握,这对以后矿山的科学勘查、合理开发资源及提高矿山经济效益起着非常重要的作用。
[Abstract]:The 3D visual modeling technology in mineral exploration has played a great role in mining exploration and production in foreign countries, but at present, this 3D modeling technology is seldom used in geological exploration units in China. Taking the Caiyuanzi Gold Mine in Muli County, Sichuan Province as an example, this paper comprehensively studies the 3D geological modeling technology of Surpac software in the process of mine exploration. The main research work and results are as follows: (1) based on the collation and analysis of the collected data of the Caiyuanzi gold deposit, a geological database of the Caiyuan gold deposit has been established. The 3D solid model of surface and gold body in Caiyuanzi gold mine area is established by using Surpac software, and the 3D visualization of ore deposit is realized. Three-dimensional visual modeling can completely and accurately express the spatial position relationship between the borehole and the gold ore body. This paper provides the basis and basis for making scientific production schedule plan of mine. It uses the principle of geostatistics to analyze the borehole sample data, and according to the statistical characteristics of the combined sample, the experimental variance function is fitted. A reasonable variation function model is established, and the block model of gold ore body. 4) based on the established block model, the gold resources of the 鈪，
