摘要
利用矿山巷道高程导线点数据与二维巷道地图数据,提出了三维巷道空间拓扑关系的自动建立方法和空间拓扑支持下的风网动态解算算法。矿山巷道通风系统的实现采用了开放源代码GIS软件技术与商业软件技术相结合的实施方案,实现了巷道数据的管理、网络拓扑的快速建立、通风过程的模拟求解、以及计算结果的可视化。其中,GDAL/OGR用于读写空间数据库,Boost Graph与MTL用于构建拓扑分析与风网解算的算法库,而ArcGIS Engine则用于矿井通风系统的可视化以及通风网络参数的管理。
By taking advantage of height traverse data and 2D laneway map data, the paper presents a new approach to automating the construction of spatial topology on 3D mine ventilation networks and a dynamic algorithm for simulating mine ventilation based on spatial topological database. The underground mine ventilation system is realized with a solution integrating open source code GIS technologies and proprietary software, whose functionalities include mine laneway management, rapid building of spatial topography, ventilation simulation and solving, and result visualization. Among programming toolkits, the GDAL/OGR is adopted for accessing spatial database, the Boost Graph and MTL for topologieal analysis and ventilation simulation, and the ArcGIS Engine for ventilation system visualization and ventilation network parameterization.
