Abstract :
The Dijkstra algorithm based on 3D roadway model was applied to improve efficiency in assistant mine disaster rescue and it has been implemented by 3D GIS technique. Designing 3D complex geological entity model was given emphases to, in order to effectively establish topological relations between 3D roadway network node model and stratum lithology. In addition, the topological relation between nodes and arcs in 3D roadway model were established. And then through applying Dijkstra algorithm, fast intelligent selection of lash-up rescue routes was made. Finally, the system structure and functions along with requirements were analyzed, and then key technologies and methods to achieve the model based on 3D GIS were expounded.
