摘　　要：井下避险GIS的三维巷道建模与网络分析是数字矿山建模的重要研究内容,也是紧急避险可视化研究的关键技术之一。文中分析了井下避险GIS的数据源和数据特点,依据GIS三维网络分析对数据模型的需求,分类设计了井下巷道网络、井下构筑物、监测与应急设施等重要信息的二维与三维的模型,研究了一种适合井下不同作业层安全监测信息立体表达的模型,和以三维线模型为主的GIS数据组织形式,实现了不同作业层面上避险信息GIS管理,为井下避险最优路径的快速确定和立体显示提供了数据模型,对矿山安全生产与矿山救援等具有重要意义。It is an important content of the digital mine modeling,and is also a key technology of research on emergency hedging visualization of 3D tunnel of the underground hedging GIS.In the paper,the author introduces analyzes the data source and data features of the underground hedging GIS,and classifies design 2D and 3D models of the underground tunnel network,the underground structures,the monitoring and emergency facilities based on the requirements of the GIS 3D network analysis.The author makes a model which is suiting for 3D expression of different underground layers in safety monitoring information,and the GIS data organizational form based on 3D linear model,and achieves the GIS information management on different operating levels hedge.It provides the data model of the optimal path determining in rapid and the stereo display of the underground hedging.It is a great significance for the mine safely production and mining rescue.
