Abstract: In order to realize the safe dispatch of trolleybuses in coal mines, a new dispatch strategy is proposed, which uses the hierarchical color Petri net as a framework to model the dispatching system. By studying the running process of the model, the security, correctness and reusability of the scheduling strategy are proved. At the same time, the basic performance of the scheduling system is simply analyzed by using the state space report of the model. The results show that the scheduling system can analyze the vehicle transportation volume, frequency of section use and its time distribution, and the degree of matching between vehicle transportation speed and transportation task generation speed, and can effectively improve vehicle transportation safety, avoid transportation accidents, assist managers in planning transportation tasks and improve mine auxiliary transportation efficiency.

Key words: underground vehicle scheduling, hierarchical color Petri net, CPN (colored Pertic net) tools, performance measurement
