摘要
矿井突水是常见的突发性强烈的灾害,当发生矿井水灾时,为了降低灾害造成的物质损失以及减少人员伤亡,提出了一种基于双向A*算法的矿井水灾逃生路径规划方法。在充分考虑影响巷道逃生因素的基础上选择合理的评估函数,利用双向A*算法对逃生路径进行规划从而实现最优设计。结合王家岭煤矿实例并将该算法的规划结果与传统A*算法的规划结果进行对比,仿真结果表明:该算法规划的逃生路径比传统A*算法节点更少,路径更优,因此在一定程度上可以提高从业人员的逃生率,具有一定的应用价值。
Mine water inrush is a sudden and intense mine disaster.In order to reduce material losses and casualties in mine flood,a mine flood escape route planning method based on bidirectional A*algorithm is proposed.With thorough consideration of the factors affecting the escape in roadways,a reasonable evaluation function is selected,and the escape route is planned by bidirectional A*algorithm to achieve optimal design.Combined with the example of Wangjialing Coal Mine and comparing the planning result of the bidirectional A*algorithm with the planning result of the traditional A*algorithm,the simulation results show that the escape route of the algorithm has less nodes than the traditional A*algorithm,and the path is better,so to a certain extent it can improve the escape rate of underground personnel.
