Abstract:  In the case that there are obstacles in the path guiding by floor field, which is designed based on the shortest distance method, the moving-cellular way is impracticable. To overcome the drawback, a new method to establish floor field is put forward by employing the shortest path from lattice point to exit. On this basis, taking the miners’ evacuation problem as an example and supposing the miners evacuate without backward move, an urgent evacuation model for miners is designed and some simulations carried out with Matlab. The results show that the established model can simulate the evacuation of miners. The average evacuation time rapidly increases along with the increase of position-keeping probability, which is consistent with the actual situation.
