摘要
目前煤矿应急救援路径优化研究多处于计算机模拟计算阶段,为了进一步推进其在实际巷道复杂环境条件下的应用,提出了一种跨平台矿井应急救援路径寻优方案。将巷道通行影响因素抽象为方便计算的影响因子,结合巷道实际长度与通行难度计算巷道当量值;将当量值作为路径长度,采用Dijkstra算法求解矿井应急救援路径;利用Unity引擎的跨平台特性,在计算机、移动端等平台运行应急救援路径寻优算法。实际应用结果表明,该方案能够绕过因事故而无法通行的路段,给出准确有效的井下避灾路径,从而为井下应急救援路径寻优的现场应用提供技术支持。
At present,research on coal mine emergency rescue path optimization is mostly in the stage of computer simulation calculation.In order to further promote its application in the actual environment of complex roadway,a cross-platform mine emergency rescue path optimization scheme was proposed.Influencing factors of roadway passage are abstracted as impact factors for easy calculation,and actual length of the roadway and passage difficulty are combined to calculate equivalent value of the roadway;Dijkstra algorithm is adopted to solve mine emergency rescue path using the equivalent value as the path length;the emergency search path optimization algorithm can runs on platforms such as computers and mobile terminals taking advantage of the cross-platform nature of Unity engine.Practical application results show that the scheme can bypass road sections that are impassable due to accidents,and provide accurate and effective underground disaster avoidance paths,thus providing technical support for the field application of underground emergency rescue path optimization.
