摘　　要：基于二维平面开展的地质找矿工作已难以适应目前的要求,而三维地质建模技术在立体成矿预测中的应用愈加广泛,其中绝大多数三维建模技术都基于矿区的钻孔数据进行建模,然而矿区外围缺乏钻孔数据给三维建模带来了困难。总结了矿区外围缺少钻孔情况下的三维地质建模流程,基于地表地质测量数据,结合高精度地球物理数据三维反演等技术,直观地刻画出地下一定深度范围内的构造、岩体、地层等空间展布的三维“地质图”,为区域大比例尺开展立体成矿预测提供基础技术支撑。In recent years,the traditional geological prospecting based on two-dimensional plane can no longer meet the needs of contemporary development.Instead,three-dimensional geological modeling technology is increasingly widely used in three-dimensional metallogenic prediction,most of which relies heavily on the borehole data in the mining area for modeling.However,due to the lack of borehole data around the mining area,3D modeling faces new challenges.This paper summarizes the process of 3D geological modeling in the environment with few boreholes.Based on the surface geological survey data,combined with the 3D inversion technology of high-precision geophysical data,the three-dimensional″geological map″of the spatial distribution of structure,rock mass and strata within a certain depth of underground can be visually depicted,which provides the basic technical support for regional large-scale three-dimensional metallogenic prediction.
