基于ArcGIS快速建立露天采场模型三维可视化法

Method of establishing a fast three-dimension visualization of surface mine model by ArcGIS

为了解决露天矿采场模型快速建立的问题。论述了一种快速建立露天矿三维模型的方法,采用了离散点生成TIN来表达地形以及各地层界面的方法,通过对AutoCAD的二次开发来提取图形单元形成建模要素,导入到ArcGIS,进而生成三维矿模。研究结果表明,该方法不仅能达到逼真的三维动态效果,而且对于矿岩量的计算更为准确方便。研究结论初步突破了露天矿算量的传统方法,有助于露天矿的日常生产和管理。

In this paper a 3D visualization method of how to establish the surface mine model fast is introduced. The method adopts discrete points to express terrain and stratum interface by creating TIN. The model elements are distilled from drawings by the secondary development of AutoCAD, and then are imported through ArcGIS, thereby we set up the 3D mining model. The researching results indicate that it makes not only 3D reality-dynamic effect, but also calculate the volume of mine and rock more convenient and accurate. The researching conclusion initially broke through the traditional method of calculating volume, and was helpful to the daily production and the management in surface mine.
