三维GIS数字矿山剖切算法研究

3D GIS Digital Cutting Algorithms of Mine

本文将GIS和BIM技术相结合,并利用可视化技术以图形图像方式逼真的再现三维地质实体等地学信息,实现了对地质实体的任意剖切.本文简要介绍了3DGIS关键技术,详细介绍了对空间对象的剖切技术.将三维实体的任意剖切技术和BIM技术相结合实现了对地质体内部属性的快速获取,使得既不影响系统显示又保证了系统的实时性.使得矿山各级生产管理部门直观、快速、精确、全面地了解矿山生产状况和储量信息.为矿山生产管理人员实施调度指挥、矿山开采等工作提供优良的决策依据.

By combined GIS and BIM technology, and using the way of graphics and images, the realistic 3D geological entity is presented by visualization technology and the cutting geological entity at any aspects is realized. This paper introduces 3D GIS key technology briefly and the cutting spatial objects technology in detail. Getting internal attributes of geological bodies at highly speed is realized by combining by technolo- gy of cutting and BIM together, which not only has no influence on system display, but also can ensure system real-time performance. This system makes mine management departments understand mine reserves information visually, quickly,accurately and comprehensively, and also provides excellent basis for decisions to mine production commanding and mining works for managers.
