【摘要】：以火灾动力学软件FDS(Fire Dynamics Simulator)在矿井巷道火灾中模拟方法为主线,建立了巷道中有无顶棚烟道的研究模型,对发生火灾时巷道温度场以及烟气变化情况进行探究。通过实验分析表明,设置顶棚烟道对巷道火灾烟气流动起到一定的抑制和疏导作用;随着风速增加,巷道中温度明显下降,热流快速分散,利于人员安全疏散。
[Abstract]:Based on the simulation method of fire dynamics software FDS (Fire Dynamics Simulator) in the mine roadway fire, the research model of whether there is a roof flue in the roadway is established, and the temperature field and the variation of flue gas in the roadway during the fire are investigated. The experimental results show that the smoke flow of roadway fire is restrained and induced by the setting of ceiling flue, and with the increase of wind speed, the temperature in the roadway decreases obviously and the heat flow disperses rapidly, which is conducive to the safe evacuation of people.
