【摘要】现有的巷道三维模型建模算法复杂,且以巷道两端端点坐标直接确定巷道的走势,不能较好地体现巷道的起伏。针对上述问题,以煤矿工程平面图为基础数据,利用巷道间的拓扑关系进行定位点采集,采用中心线加载断面的算法构建了矿井三维巷道模型。基于矿井三维巷道模型,将通风设施模型同步到三维系统中,生成了矿井通风系统三维模型及相应数据库,生成的立体图能清晰地展示矿井巷道的整体走势,结合数据库信息管理可对矿井模型进行添加、修改等智能操作。实际应用结果表明:该模型实现了矿井通风系统二维图到三维图的快速转换,可真实地展示煤矿巷道信息及工作面状况,生成的矿图数据库可实时更新,为研究矿井通风网络解算和灾变模拟提供了优良平台。
【Abstract】The existing modeling algorithms of three-dimensional roadway model are complex, and the trend of roadway is directly determined by the coordinate of the endpoints of roadway, which cannot reflect fluctuation of roadway well. In view of the above problems, taking engineering plan of coal mine as basic data, a three-dimensional coal mine roadway model was constructed by using topological relationship between the roadways to collect location points and using algorithm of loading section of center line. Based on the three-dimensional roadway model, a three-dimensional model of mine ventilation system and corresponding database were generated through synchronizing ventilation facility model into the three-dimensional system. The generated three-dimensional map can clearly show overall shape of the mine roadway. Combined with database information management, the intelligent operation such as adding and modification of the mine model can be achieved. The practical application results show that the model can realize fast conversion from two-dimensional drawing to three-dimensional drawing of the mine ventilation system, display information of mine roadway and condition of working face truly, and the database of the mine map can be updated in real time, which provides a good platform for research of mine ventilation network solution and disaster simulation.
