摘要:

最优应急避灾路线的确定是安全有效逃生的第一步。针对井下实际应急逃生情况的需要,定义了矿井火灾三大避险原则,对通行路径的安全系数进行量化分析并提出了行进速度影响因子的计算方法,结合巷道安全系数与行进速度影响因子构建了巷道逃生路径优化数学模型。根据巷道当量长度计算公式,将井巷网络图转换为巷道当量网络图,在此网络图的基础上通过Dijkstra算法求解人员位置点到安全点的最短路径,从而确保逃生路径的安全与快捷。最后,将模型应用到云南某金属矿山,为矿井火灾辅助逃生系统提供借鉴与技术支持。

Abstract:

Determination of the optimal emergency escape route is the first step of safety and effective escape.According to the need of the actual emergency escape situation,defining the three hedge principle of mine fire,analyzing the safety factor of the passage and proposing the calculation method of the influence factor of travel speed,and then the optimization mathematical model of the escape route was constructed.According to the formula of equivalent length of roadway,convert the roadway network to the equivalent network diagram,on the basis of this network graph,the shortest path from personnel location point  was solved by the Dijkstra algorithm thus ensure the safety and quick escape route.Finally,the model was applied to a metal mine in Yunnan Province,it provided reference and technical support for mine fire escape system.

Key words: mine fire, safety factor, impact factor, equivalent length of tunnel, roadway equivalent network
