中文摘要: 为了解决现有静态路径规划方法无法满足煤矿井下突水灾害动态变化需求,以及传统最短路径算法运行效率有待提升等问题,提出一种基于策略的矿井水灾避灾路径动态规划方法及系统。该方法考虑水流对人员逃生的影响,首先将巷道环境影响因子对避灾路径的影响程度量化为巷道距离当量长度;然后以时间最短为原则,引入人员逃生速度,计算逃生通过每条巷道的时间,构建以逃生时间为邻接矩阵的数学模型;并结合安全监控、水文监测系统联动策略,根据实时监测的井下环境情况,动态修改巷道节点属性,开发基于三维GIS一张图的矿井水灾避灾路径三维动态规划系统。最后,结合矿井实例进行测试分析,验证了算法设计的有效性,可以指导井下人员安全撤离,提高煤矿安全管控能力。

Abstract:In order to solve the problems that the existing static path planning method can not meet the dynamic change demand of underground coal mine water inrush disaster, and the operation efficiency of the traditional shortest path algorithm needs to be improved, a strategy-based dynamic path planning method and system for mine flood disaster avoidance was proposed. The method considers the influence of water flow on personnel escape. Firstly, the influence degree of roadway environmental factors on disaster avoidance path is quantified as the equivalent length of roadway distance. Then, based on the principle of the shortest time, the escape speed was introduced to calculate the escape time through each roadway, and a mathematical model was constructed with the escape time as the adjacency matrix. Combined with safety monitoring and hydrological monitoring system linkage strategy, according to the real-time monitoring of downhole environment situation, the dynamic changes of roadway node properties, development based on 3 d GIS a figure of mine flood disaster avoidance path three-dimensional dynamic programming system. Finally, combined with the test analysis of mine examples, the effectiveness of the algorithm design is verified, which can guide the safety evacuation of underground personnel and improve the ability of mine safety control.
