【摘要】 分析了井下避险的影响机理,从巷道安全性和避险效率2方面建立通行的量化指标;在改进的Dijk-stra算法基础上引入了避险效率的等价权因子,形成井下避险最优路径的算法模型,并以井下灾前及灾后的巷道通行网络图进行仿真验算。实验结果表明,与改进的Dijkstra算法相比,最优避险路径算法求解路径更安全有效,可为井下人员逃生最优路径选取和避险路线优化设计提供数学模型与定量分析。更多还原

【Abstract】 The hedge route is the life line of the underground personnel,and is also the first step to implement effective hedge.In this paper,the impact mechanism of underground hedge is analyzed,and the prevailing quantitative indicators are established from the roadway safety and hedge efficiency.The algorithmic model of underground hedge’s optimal path by introducing the equivalent weight factors of hedging efficiency based on the improved Dijkstra algorithm.It also conducts simulation by the tunnel network diagrams of underground pre-disaster and post-disaster.The experimental results show that the algorithm of optimal hedging path is more effective than the improved Dijkstra algorithm to solve path.It provides mathematical model and quantitative analysis for the selection of optimal path and the optimization design of hedge route.更多还原
