【摘要】：地球作为一个有限体,人类赖以生存的自然资源是有限的。随着社会的进步,人类对矿产资源的需求量也大幅增涨,矿产资源的占有量已成为决定国家富强,影响社会繁荣的重要因素之一,这使得地质学中的找矿研究变得越来越重要。将传统的地质科学与现代信息化技术相结合,力争解决现有研究中的不足,是地质科学发展的必然趋势。随着计算机技术的发展,三维地质软件的推广和应用也日益受到重视。国内的三维可视化技术虽然起步较晚,但发展迅猛,并已广泛应用于数字矿山信息系统的建立、直观精准的圈定矿体、储量计算、矿山生产设计等多个方面。“数字矿山”解决了许多传统矿业所面临的难题,也大大提高了矿山的工业水平和工作效率。本文在结合国内外三维可视化研究的基础上,通过分析贵州省望谟县里来金矿的地质特征,采用Micromine矿业软件,构建了里来金矿数字化模型,并以此为研究对象,探讨了实现该信息系统的关键技术及相关的应用研究。本项研究取得的主要认识和结论如下：(1)利用Micromine软件建立了里来金矿数据库,实现了钻孔的空间定位和显示、矿体的各类有效信息数字化、可视化。(2)在矿山地质数据库的基础上依次建立了地形模型(DTM)、地层模型、构造模型及矿体模型。可对资料数据进行增删、修改和动态查询,对矿山的生产工作动态管理具有现实意义。(3)以变异函数作为主要工具,对Au的单样、组合样进行统计分析,包括均值、方差、标准差、频率分布及品位分布,并绘制了品位分布直方图。同时利用变异函数对勘探网度的合理性进行分析,建议勘探网度为35m×38m较合理。(4)建立了里来金矿的品位模型,实现了快捷的储量计算,并提交了储量报告和报表,绘制了品位-吨位曲线图,为后期矿山的勘查设计和开采优化方案设计提供科学可靠的指导思想。(5)通过矿床经济评价,提高矿山生产效益,从而减少资源浪费,并以平衡品位重新圈定矿体。
[Abstract]:The earth as a finite body, human survival of the natural resources are limited. With the progress of society, people's demand of mineral resources also increased markedly, the possession of mineral resources has become one of the important factors affecting the country's prosperity, prosperous society, which makes the research of geology prospecting have become more important. Geological science and modern information technology combining traditional and strive to solve the deficiency of existing research, is the inevitable trend of development of geological science. With the development of computer technology, 3D software promotion and use should pay attention to increasingly. The 3D visualization technology started late, but rapid development, the establishment of it has been widely used in digital mine information system, accurate calculation direct delineation of ore reserves, many aspects of mine production design. "Digital mine" to solve the many The problem facing the mining industry, but also greatly improve the mining industry level and work efficiency. On the basis of 3D visualization research at home and abroad, through the analysis of the geological characteristics of Guizhou Province, the county to Wangmo gold mine, using Micromine mining software, built in gold mine digital model, and as a research object, study the research on the key technology of the information system and related applications. The main ideas and conclusions of this study are as follows: (1) established in gold database using Micromine software, realize and display the spatial location of the drilling, the visualization of all kinds of effective information digitization, orebody. (2) based on mine geological database in turn on the established terrain model (DTM), stratum model, structure model and orebody model. Additions and deletions can modify the data and dynamic query, dynamic production of mine Management has practical significance. (3) the variation function as the main tools for Au single sample, the composite samples were analyzed, including mean, variance, standard deviation, frequency distribution and grade distribution, and grade distribution histogram drawing. At the same time, the rationality of prospecting network analysis using variation function, proposed exploration network the degree of 35m * 38m was reasonable. (4) established in gold grade model, realizes the fast calculation of reserves, reserves and submitted reports and statements were drawn, the grade-tonnage curve for later exploration and exploitation of mine design optimization scheme is designed to provide reliable scientific guidelines (5). Through the economic evaluation of deposit, improve the production efficiency of the mine, so as to reduce the waste of resources, and to re balance grade orebody.
