三维地质建模技术在地勘找矿中的应用

Application of 3D geological modeling technology in geological prospecting

传统地质勘查成果的表达主要采用剖面图和平面图,这种表现形式的实质就是将三维空间当中的地层,地貌和构造以及一些其它的地质现象反映到某一个平面上进行表达。虽然该方法也能够获得一定的信息,但是其空间信息的损失与失真和制图过程的繁杂及更新困难不足也是显而易见的。近年来,三维地质建模技术有了飞速的发展,该技术的提出有效克服了传统方法的不足,其利用计算机与可视化技术,能够直接从三维空间的角度来表达地质体及地质环境。基于此点,本文首先对三维地质建模在地质找矿应用中的关键技术进行概述,并在此基础上对三维地质建模技术地勘在找矿过程中的实际应用进行研究。

The traditional expression of geological exploration results mainly uses section map and plane map.The essence of this form of expression is to reflect the stratum,landform and structure in three-dimensional space and some other geological phenomena on a certain plane.Although this method can also obtain certain information,it is obvious that the loss and distortion of spatial information,the complexity of mapping process and the difficulty of updating are also obvious.In recent years,3D geological modeling technology has developed rapidly,which overcomes the shortcomings of traditional methods.It can directly express geological body and geological environment from the perspective of 3D space by using computer and visualization technology.Based on this point,this paper first summarizes the key technologies of 3D geological modeling in geological prospecting,and on this basis,studies the practical application of 3D geological modeling technology in geological prospecting.
