摘要
在AutoCAD平台下,以某露天矿为例,建立地质数据库,根据断层线构建断层线框模型以及采场现状图和地形等高线构建地形模型,根据钻孔数据和内插点构建矿岩实体模型,实现了露天矿三维地质模型的可视化显示;根据矿岩实体模型建立块体模型,对块体模型添加属性、赋值,并将其应用到露天矿采剥工程量计算中,与传统算量方法相比,该方法操作简单,提高了计算的速度与精度。
Take an open pit as a case, AutoCAD is used as raftware platform and a geological database should be constructed. According to fault wire-frame model constructed by fault lines, terrain model through topographic contour map and stope status map and ore & rock solid model constructed through borehole data and interpola- tion points, three-dimensional visual display of geological model in open-pit can be realized. Block model is constructed according to ore & rock solid model, and then the attributes of block model are added and assigned. Quantities of mining & stripping in open-pit are calculated by using block model. Calculation speed and precision are increased compared with traditional quantity calculation methods.
