摘要
随着21世纪工业的快速发展,人们对矿产资源的需求日益扩大,然而我国一大批矿山却面临着严重的资源危机,解决危机矿山的根本是加大矿山周边和矿山深部的找矿工作。同时,随着地学研究和勘查工作的不断深入,积累了海量的地学数据,矿产勘查己进入信息找矿的新时代。矿山三维地质建模与可视化技术研究,是"数字矿山"的核心组成部分,是现代矿山信息化研究的热点和重点。本文从三维地质建模的概念出发,探讨了基于钻孔数据的矿山三维地质建模及可视化的一般过程,包括地质数据库的建立,实体模型、品位块体模型的创建等,通过在沂南金矿成矿预测研究中的具体应用,探讨了三维地质建模及可视化应用于危机矿山成矿地质条件分析及大比例尺成矿预测中的过程和方法,为矿区成矿规律的研究和危机矿山的成矿预测提供了有效的技术手段,大大地提高矿产勘查的效率,促进了我国矿山信息化的建设。
In the 21 century, with the fast development of industry, there is much demand for the mineral resources, however a few mines face serious resources crisis. Looking for ores in the perpheries and at deep levels of the mines is a basic and main way to solve the crisis. Additionally, with the development of geosciences and the continuing progress of mineral exploration, mass geoscience data have been accumulated, the era in which we live has been described as the age of information prospecting in terms of mineral exploration. Study on 3D geological modeling and visualization of mines is the important part of ＂Digital Mine＂, and also is the research hotspot on the computerization of modern mines. The paper discussed the general process of 3D geological modeling and visualization of mines based on borehole data from its concept, including the establishment of geological database, the creation of solid model and grade block model, etc. By applying it to the project about gold deposit prediction in Yinan, this paper discussed the method and process concerning the application of 3D geological modeling and visualization to the analysis of ore-forming geological conditions and large-scale metallogenic prediction in resources-crisis mines. It will provide a kind of effective method and means for metallogenic study and prognosis in crisis mines, and greatly improve the efficiency of mineral exploration, and also promote the informatization construction in mines.
