文章论述了一种在AutoCAD平台下建立露天矿三维地质模型的方法。以图形单元作为建模要素,采用顾及台阶属性Delaunay三角网凸包算法建立界面模型,通过面域拉伸和实体布尔运算等方法生成三维矿模。研究结果表明,该方法不仅能达到逼真的三维动态效果,而且对于边坡稳定性分析更为准确方便,有助于露天矿的日常生产和管理。
This article discusses a method of establishing 3D geological model of open pit mine under AutoCAD platform. Taking the graphic element as the modeling element, an interface model is established by using the Delaunay triangulation convex hull algorithm taking into account the step attribute. The 3D mineral model is generated by the method of area stretching and physical Boolean operation. The results show that this method can not only achieve realistic three-dimensional dynamic effects, but also provide more accurate and convenient slope stability analysis and contribute to the daily production and management of open-pit mines.
