井下避险路线的GIS数学模型与水灾仿真实验

The GIS mathematical model and flood simulation of underground emergency route

综合考虑了灾害发生时的影响范围、路径安全性、人员避险效率等诸多影响因素,建立井下人员最优避灾路线算法模型。按照安全性最高、路径最优、时间最短的避险原则,在改进的Dijkstra算法的基础上增加了等价权因子,建立井下应急避险最优路径的数学模型。以河北杏山矿井下巷道信息数据为例,模拟井下透水灾害的水流漫延路径,利用井下避险GIS数学模型进行仿真解算,求解灾害发生时人员避险的最优路径。

It is considered a lot of influence factors of disaster range,path safety,miner＇s abil ity when disasters happen, and conducted algorithm model of underground optimal escape routes. It is established underground emergency refuge optimal path＇s mathematical model by hedging principle which is the highest security, the optimal path and the shortest time, introduced the e quivalent weight factor based on the improved Dijkstra algorithm. The flood simulation experi ment is conducted with the basic data that is related to the underground information of Hebei Xingshan Mining, and meanwhile the simulation is solved through the GIS mathematical model of underground hedge to determine the optimal path when disasters happen.
