地质及巷道集成3维模型的研究与应用

Research and Application of 3D Geological and Laneway Integrated Model

针对目前地质和巷道独立建模给矿井灾害救援带来的问题，建立了基于面模型的多层3维地质与巷道集成模型，并结合可视化技术为救援决策提供可视化的技术支持。研究了复杂地质体的3维模型和巷道3维模型的关键技术，并给出了基于多层3维地质建模及基于巷道断面构建3维巷道模型的实现方法；最后结合3维巷道网络的弧-节点模型与地层岩性、节点相互关联的拓扑关系，实现了二者的集成建模。在此基础上，采用启发式路径搜索的A＊算法．实现了应急救援路线的智能快速选择。这种集3维地质模型、巷道模型为一体的可视化系统对于矿井的事故救援或定位事故发生地点具有很强的实用性。

To solve the problems in mine disaster rescue arising from separate geological model and laneway model, a muhilayer 3D model was proposed, which combined the geological model, laneway model and 3D visualization technique. First the techniques needed in 3D model for complex geological body and laneway 3D model was elaborated. Then an integrated 8D model based on the multi-stratum 3D geological model and 3D laneway section model was established. Finally an implementation method was designed which took into consideration topological relationship of node-arc model with stratum lithology and node correlations. From that, the heuristic searching algorithm was further applied to our model and implement intelligent selection of emergency rescue routes. The result demonstrated that this integrated system of 3D geological model with taneway model and 3D visualization technique had great practical value in rescue of mine disaster and in location of the disaster spot.
