摘要
紧急避灾路线确定是实施有效避险的第一步,紧急避险路线优化与建模是应急救援系统的基础研究。通过分析通行路径可靠程度、人员避险效率等因素对避险路径的影响,确立了主要影响因素分层量化综合定权的方法,并按照安全性最高、路径最优、时间最短的避险原则,在改进的Di-jkstra最短路径算法上增加等价权因子,构建了井下人员最优避灾路线算法模型,以河北某矿井下基础数据为例进行了灾害仿真实验,为井下紧急避险GIS系统最优路径可视化确定提供了数学基础。
The determination of emergency escape routes is the first step to implement effective refuge, the optimization and modeling of emergency refuge route is one of basic research of mine emergency rescue system. The effects of esca- ping path reliability and personnel hedge efficiency on emergency refuge route were analyzed, the comprehensive weighting method of main effecting factors was determined, and mathematical model of optimal path of underground emergency refuge was established in accordance with the principles of maximum security, optimal hedging path and minimum escaping time, while a equivalent weight factor was added to improved Dijkstra shortest path algorithms. With basic data of some mine in Hehei,a simulation example was carried out to determine the optimal path when disasters happen. The study provides a mathematical basis for the visualization realization of optimal path in underground emer gency refuge GIS system.
