On 3D Geo-visualization of a Mine Surface Plant and Mine Roadway

构造一个煤矿的虚拟景色是的 3D 为在煤采矿上现代化并且处理信息的客观要求生产。建立“一个数字矿”也是关键技术。由探索当前的世界范围的研究，软件和硬件工具和应用程序要求，与案例研究地点(Pingdingshan 煤组的 Daz-huang 矿) 结合了，为一个矿的 3D geo 可视化的一条途径出现工厂和矿车道深深地被讨论。在这研究，虚拟景色基于弧 / 信息和 Site-Builder3D 被学习的为一个大范围的快速的建模方法，和从 2D 景色的 3D 景色的自动产生被认识到。能从 2D 把矿车道系统变换成 3D 的如此的一个自动方法为 Dazhuang 矿被认识到。一些相关应用程序问题被学习，包括在在矿表面的虚拟景色的虚拟场面种的 2D 和 3D 和矿车道之间的属性质问，并列质问，距离措施，碰撞察觉和动态相互作用。一个原型系统被设计并且发展。

Constructing the 3D virtual scene of a coal mine is the objective requirement for modernizing and processing information on coal mining production. It is also the key technology to establish a ＂digital mine＂. By exploring current worldwide research, software and hardware tools and application demands, combined with the case study site （the Dazhuang mine of Pingdingshan coal group）, an approach for 3D geo-visualization of a mine surface plant and mine roadway is deeply discussed. In this study, the rapid modeling method for a large range virtual scene based on Arc/Info and SiteBuilder3D is studied, and automatic generation of a 3D scene from a 2D scene is realized. Such an automatic method which can convert mine roadway systems from 2D to 3D is realized for the Dazhuang mine. Some relevant application questions are studied, including attribute query, coordinate query, distance measure, collision detection and the dynamic interaction between 2D and 3D virtual scenes in the virtual scene of a mine surface plant and mine roadway. A prototype system is designed and developed.
