Based on the 3D terrain model and the 3D geological model of surface mine, the mining template is determined by the actual production situation of surface mine, to implement the simulation of surface mining by moving these templates to slice 3D models. Volume classification of rock and coal can be determined by solid modeling and boolean operation between solids, and then the mining plan is determined. The engineer may choose the best design from several planned designs. The proposed method improves the speed and the quality of long term design planning by virsualizing the digital exploration process., correspAuthors=null, authorNote=null, correspAuthorsNote=null,

articleAbstract=为了实现露天矿三维数字化虚拟开采,提出了一种基于层间组合和定位显示技术驱动开采模板、动态切割实体模型的数字开采方法。在建立露天矿数字化三维地形模型、三维地质模型的基础上,根据矿山工程发展状态及几何约束关系,定义了以台阶为单元的分层式开采模板和驱动开采模板,从而实现露天矿的开采过程仿真。以不规则实体构模技术及实体间布尔切割运算技术作为矿岩量快速分类计算的技术手段,快速形成多个开采方案,使多方案设计对比择优成为可能,提高了采矿设计的速度和质量。研究结论为露天矿进行长远规划及定制长期计划提供了技术支撑。,
