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 shelter route is the first step to implement effective hedging. The optimization and modeling of emergency shelter route is the basic research of emergency rescue system. By analyzing the impact of the passage reliability, personnel hedging efficiency and other factors on the hedging path, a method of stratification and quantification of the main influencing factors is established, and according to the hedging principle of the highest safety, the best path and the shortest time , An equivalent weighting factor is added to the improved Di-jkstra shortest path algorithm to construct the algorithm model of the optimal hazard avoidance route for miners. A disaster simulation experiment is carried out with a basic data of a mine in Hebei Province as an example, The system optimal path visualization provides a mathematical basis.
