摘　　要：深井矿山火灾产生的高温有毒烟气在井下狭长受限空间内流动不仅损坏井下设备和影响正常生产,而且污染井下作业环境,严重威胁井下人员的生命健康。为了减少矿井火灾后的人员伤亡,为更好地应急决策提供参考,本文对矿井火灾疏散风险和疏散路线进行了研究。在前人的研究基础上本研究利用火灾动力学软件Pyrosim建立金属矿山模型,同时在最坏情况假设下选择最容易发生火灾的地点来模拟矿井火灾并观察其温度、CO浓度、烟气可见度在矿井中的变化,基于温度、CO浓度对矿井每个区域进行风险评估。利用Pathfinder进行火灾疏散模拟,同时考虑了个体之间的差异,通过对疏散模拟结果分析得出若干可行的疏散路径,通过对得出的若干条疏散路径的风险值进行加权计算并比较得出一条最佳疏散路线。在前人的研究基础上,本研究提出了一种新的矿井疏散路线选择模型,更直观地展示了矿井不同区域的疏散风险分布,可为今后矿井火灾数值模拟研究提供参考。In order to reduce casualties after mine fires and to provide reference for better emergency decision-making,the risk of mine fire evacuation and evacuation routes have been studied in this paper.In this paper,based on previous research,we use Pyrosim,a fire dynamics software,to build a metal mine model.At the same time,under the worst-case assumption,the most fire-prone location is selected to simulate the mine fire and observe the changes of temperature,CO concentration and smoke visibility in the mine,and evaluate the risk of each area of the mine based on temperature and CO concentration.The fire evacuation simulation was carried out by Pathfinder,taking into account the differences between individuals,and several feasible evacuation routes were derived by analyzing the evacuation simulation results.Based on the previous work,this paper proposes a new model for mine evacuation route selection,which can show the evacuation risk distribution in different areas of the mine more intuitively and can provide a reference for future numerical simulation studies of mine fires.
