文章利用FDS软件建立某矿井通风系统巷道的数值模型,采用混合燃烧模型进行火灾模拟,并根据该模拟结果分析热辐射,烟气温度、二氧化碳浓度等有害因素参数随时间的变化结果。综合分析火灾产生的有害因素对人员健康度的影响,为井下火灾的疏散及灾害条件下的人员健康状态评估提供量化标准。
In this paper, we use FDS software to establish the numerical model of a mine ventilation system roadway, and use the hybrid combustion model to simulate the fire. According to the simulation results, we analyze the change of the parameters of harmful factors such as heat radiation, flue gas temperature and carbon dioxide concentration with time. Comprehensive analysis of the impact of fire hazards on the health of personnel, to provide quantitative standards for the evacuation of underground fires and assessment of health status of personnel under disaster conditions.
