Micromine三维建模在包金山金矿地质找矿中的应用
|
摘要
近年来随着数字化技术不断完善与提高,已经出现了数字化地球、数字化社会等新概念。因为Micromine矿业软件可以提供一个三维可视化的成矿预测综合分析平台,所以本文使用Micromine对包金山金矿各地质体进行三维建模。在构建矿区三维模型基础上,通过分解各地质体,单独研究各个地质体的空间分布和空间形态,通过多个不同地质体之间的组合,从三维空间上对其相互关系进行分析,以厘清各地质体对于成矿的影响,通过对矿体模型品位赋值,将金元素浓度在矿区的整体分布情况可视化,找出矿体矿化富集特征,总结矿区的成矿规律,最终对矿区进行全面的成矿预测。
In recent years, with the continuous improvement and improvement of digital technology, new concepts such as digital earth and digital society have emerged.Because Micromine Mining Software can provide a three-dimensional visualization of the comprehensive analysis platform for mineralization prediction, this paper uses Micromine to carry out three-dimensional modeling of the plastids around the Baojinshan gold deposit.On the basis of constructing the three-dimensional model of the mining area, the spatial distribution and spatial morphology of each geological body are studied separately by decomposing the local plastids,through the combination of different geologic bodies, the relationship between them is analyzed from three-dimensional space to clarify the influence of plastids on mineralization, through the assignment of the ore body model grade, the overall distribution of gold concentration in the mining area is visualized, the mineralization and enrichment characteristics of the ore body are found out, the ore-forming rules of the mining area are summarized, and the comprehensive ore-forming prediction of the mining area is finally carried out.
