摘要本学位论文基于国内外三维建模以往的研究成果,对矿体资源估量与三维矿体建模相关原理进行了初步的介绍,就当前矿体资源储量估算和三维矿体建模的有关应用进行了解析,预测了其未来的发展趋势。以新疆哈密市XX铜矿为例,研究了以QuantyMine 软件系统为基础的矿体资源储量估算和三维矿体建模的基本原理和相应的技术流程。采用多种研究相结合的方式,将理论知识用于实践、将建模技术体现于地质调查中、定性与定量分析结合、新型技术方法与传统理论结合起来,取得以下进展: (1)以 QuantyMine 软件系统为平台,建立了XX铜矿钻孔数据库,为后续的三维矿体建模和储量估算提供了基础。 (2)对国内外三维矿体建模以及矿体资源储量估算相关研究的基础上,对建立复杂矿体模型中有关人机交互式处理的方案进行了深入研究,并对建立与实际相符合的复杂地质矿床模型中的储量计算方法和技术基础做了比较系统全面的阐述,同时对其未来的发展趋势进行了预测。 (3)为了有效地探索矿山生产及其管理模式持续发展的情况,结合地质理论,在三维地质体可视化技术的基础上建立了矿床三维模型。以XX铜矿矿体模型为平台,对矿体剖面圈定的有关原则进行阐述,提出了构建矿体线框模型的方法以及应对特殊情况的解决措施,其应用研究也获得了相应的成果。相信在今后,随着技术的不断进步和推广,以及使用者对其认识的不断深入,三维地质体可视化技术的使用范围会越来越广。 (4)距离反比法是本文进行铜矿体资源储量估算的主要方法,本文以铜矿体的实测数据为准,对该评估方法的可靠性进行了验证,对其误差进行了评估。另外还评估了封闭多面体法的可靠性和误差。对上述两种方法的结果进行了进一步对比后认为距离反比法更适用于本文的研究。
其他摘要Based on domestic and foreign previous studies, this paper focus on 3D modeling of ore body, and estimate reserves. The development and advance of the 3D technology and estimating were summarized at the beginning of this paper. In this paper, we take XX mine in East Tianshan erea as an example. The basic principle and technical flow of the ore body reserves estimation and 3D ore body modeling based on QuantyMine software system are studied.. The combination of a variety of research, theoretical knowledge into practice, will reflect the modeling technology in geological survey, qualitative analysis and quantitative analysis combination, the new method and the traditional theory combined, some progress has been made: (1) The database of XX copper mine is built on the basis of QuantyMine software system, which provides a basis for the subsequent 3D ore body modeling and storage estimation. (2) The 3D orebody modeling and ore reserves estimation based on the related research, on the establishment of complex ore body model in the man-machine interactive processing scheme were in-depth study, complex geological model and to establish and conform to the actual reserves calculation method and technique foundation made a more systematic and comprehensive exposition, and the future development trend is predicted. (3) In order to explore the sustainable development of mine production and its management mode, the three-dimensional model of the deposit is built on the basis of the geological theory and the visualization technology of 3D geologic body.. To XX orebody model as a platform, section of ore body delineation of the relevant principles proposed constructing orebody wireframe model method and deal with special circumstances, solutions, and the study on the application of also won the corresponding results. I believe in the future, with the continuous progress of technology and the deepening of its awareness, the use of three-dimensional visualization technology will become increasingly wide range of use. (4) Inverse distance method is copper ore reserves estimation methods used in this article, the measured data in copper ore bodies shall prevail, to the evaluation method of reliability was verified. The error was evaluated. The reliability and error of the closed polyhedron method are also evaluated.. The results of the two methods are compared, and the distance inverse method is more suitable for this study.
