Mathematical model and algorithm of a dynamic optimum rescue route during mine fire time based on MapObject

The graph-theory method was used to build a mathematical model of the optimum rescue route during mine fire time and an improved Dijkstra algorithm was brought forward to calculate it. Then each step of the Dijkstra algorithm was discussed, and the residence and moving time-temperature function was fitted. Finally, taking the mine hazard emergency rescue system of Dong-pang mine as an example, through operation the decision maker can get the optimum rescue route on the Dongpang mine tunnel distribution sketch map. The software realizes the requirement of visualization with high efficiency and provides powerful technical support for mine fire rescue.
