Abstract
In view of problem of underground personnel safety evacuation when accident occurs, an underground personnel safety evacuation model was established. Underground tunnels are divided into grids, and distance between the grids and evacuation exit is reflected by setting members potential flow, so as to determine moving direction and evacuation route of evacuees. Evacuation time is obtained through combination of moving speed and response time of evacuees and detection time of disaster. The simulation results show that the model can directly present dynamic process of evacuation and provide data reference for safety evacuation scheme.
