摘要
目前地矿信息获取手段多样化、地矿数据的时空性以及多源化,造成了矿产资源勘查和评价难度日益增大,从单一的找矿手段获取单方面的矿化信息已远远不能满足现代找矿工作的需要。综合使用各种有效的找矿方法、获取多源地学信息,并通过一定的技术手段和途径进行信息的合成,从而获取深层次的隐蔽信息,已成为当前矿化信息研究的一种必然发展趋势。
     对矿区地下矿体进行三维可视化不失为经济找矿的一条捷径。地质体的三维可视化是在充分利用矿山大量原始数据的前提下,在摸清矿体、地层岩性、地质构造的空间构架及其相互关系基础上,对多源地学信息与矿产信息进行相关性处理和复合处理,建立多源地学信息与矿体或矿脉的相关物理模型及数学模型,最终有效地实现相对复杂而且分布不规则地质体的三维可视化和重建。通过观察地质体三维模型,进行矿体群空间展布规律的分析,进而对矿床进行地质分析和找矿预测以及对矿山的采矿设计、日常生产管理和生产进度管理提供依据,为有效地提高矿山的现代化管理水平奠定基础。
     IDL(Interactive Data Language)作为面向矩阵、语法简单的第四代可视化语言,是进行二维及多维数据可视化分析及应用开发的理想软件工具。从其语法简单、内嵌各种丰富的算法库、对三维真体数据的支持、面向对象的编程方式等特点来看,是一种进行地质三维建模的理想开发语言。
     本文在数字化、可视化思想主导下,以云南省广南县老寨湾金矿区数字矿山的空间信息为研究对象,运用IDL可视化语言建立地质体三维可视化模型系统,从原始数据的导入到建立地质体三维模型及基于模型的空间分析,始终是以可视化技术为手段,以地学问题为核心的。在三维地质建模技术和现状的基础上,从系统和应用的角度出发,实现地质体的三维立体可视化,从而更全面的了解地质体的空间展布规律,指导对矿山的深边部预测找矿。
     既要真实地模拟地质体,又要充分利用原始数据是本文的主要目的。本文在分析矿山地质概念模型基础上,结合矿山地质特有的各种地质现象提出一种表面与实体相混合的空间数据模型并设计了数据结构。在这种混合数据模型中,可以通过选择一个或多个合适的数据模型对矿山地质各种空间目标进行描述,从而较为完整地表示空间目标的几何和拓扑关系,基本达到了简单实用的目的。
At present, the mineral data are characterized by time-space and multi-sources and the means for acquiring mineral information are diversiform, which make the mineral resources exploration and evaluation increasingly complicated. The single access to acquire the mineral information has been far from away to meet the needs of modern mineral exploration. According to the comprehensive and effective mineral exploration methods, we can acquire the multi-sources of geoscience information. And also according to some technology and certain means for the synthesis of information in order to obtain the in-depth and hidden information has now become an inevitable trend of the research of the mineral information.
     Using three-dimensional visualization for the underground ore body can be a shortcut to the economic prospecting. On the premise of the full use of a large number of raw data in the mine and on the basis of finding out ore body, stratum lithology, the geological body of space structure and mutual relations, the three-dimensional visualization of the geological body processes the multi-sources of geoscience information and the mineral information with correlation and compound as well as builds the relevant physical models and mathematical models of the multi-sources of geoscience information and ore body or vein.In the end, it can realize the effective three-dimensional visualization and reconstruction of the relatively complex and irregular distribution of geological body. By observing the three-dimensional model of geological body and analysing the law in group spatial distribution of ore body, it can provide a gist to the geological analysis in the deposit, mining forecasting,mining design, day-to-day management and production management, so it can establish a basis for effectively improving the modern management level in the mine.
     As a matrix-oriented, simple syntax of the fourth generation of visual language, IDL (Interactive Data Language) is the ideal software tool of two-dimensional and multi-dimensional data visualization analysis and application development. From the characteristics of simple syntax, the rich variety of using embedded algorithm library, the support to the real three-dimensional data, object-oriented programming, IDL is an ideal development language of the three-dimensional geological modeling.
     In this paper, under the guidance of Digitalization and visual thoughts, using the space information of digital gold mine in Yunnan Province Guangnan District Laozhai Bay as research object, it uses IDL visual language to build the three-dimensional visualization model system of geological body. Not only the introduction of the raw data, but also the establishment of three-dimensional model of geological body and spatial analysis based on the model, it is always based on the visualization technology as the means and the geoscience issues as the core. On the basis of three-dimensional geological modeling technology and the status quo, from the view of systems and applications, it has the realization of the three-dimensional visualization of geological body, and thus we can get a more comprehensive understanding of the geological body spatial distribution rules to guide the deep and edge mine forecast for prospecting.
     Not only simulating the real geological body, but also making full use of the raw data is the main purpose of this article. Based on the analysis of mine geological concept model, combined with all kinds of unique geological phenomena of mine, it puts forward a spatial data model mixed of surface and entity and also designs the data structure. In such a mixed data model, it can select one or more appropriate data model for the describing of the variety of space targets in the geological mine in order to more fully express the relationship between geometry and topology of the space target, and reach a simple and practical purpose.
