元宝山露天矿矿床地质模型的构建及其可视化研究

本文紧紧围绕露天矿地质模型的建立及其显示这一主题，将矿床地质模型分为地质界面模型和矿床实体模型。用加权趋势面法对地质界面进行估值，生成地质界面的插值曲面；用边界多边形及断层对地质界面进行裁剪，形成地质界面的裁剪曲面；以地质界面的裁剪曲面和地表面的三角剖分面按空间组合成矿床实体模型。以元宝山露天煤矿为倒，实现了矿床模型的三维可视化。

Establishment and Visualization of Geological Model of Yuan Baoshan Surface Coal Mine

This article centers on the establishment of surface mine's geological model and its display. The geological model was composed with geological interface model and body model. The interpolation surfaces of geological interface were generated with estimating method of weighted trend surface. The geological interface was cut in by boundary and fault and converted into trimmed surface of geological surface. The trimmed surface of geological surface and the triangulation earth's surface constituted the body model spatially. The author took Yuan Baoshan Mine for example,realized the display of the 3D deposit model in any direction.
