Application of Dijkstra Algorithm in Underground Escape Training System

Underground escape training is an important part of coal mines safety education, and has great guiding significance for the scene escape of underground workers. Combined with the actual situation of underground roadway and the needs of system, we determine the equivalent length of roadway and the escape velocity, and then realizes the application of Dijkstra algorithm in the system by using VSL programming. It not only overcomes the defects of Virtools which can not realize the shortest path algorithm by bringing its own BB modules, but also greatly promotes the application of the shortest path algorithm in virtual training system.
