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。
Taking fire dynamics software FDS( Fire Dynamics Simulator) in mine roadway fire simulation as the main line, we establish the study model with or without roof flue in mine roadway, and study the change of temperature field and flue gas when there is a fire. Through the experimental analysis, setting roof flue for mine has a certain inhibition and guidance role for fire smoke flow; with the increase of wind speed, temperature significantly decreased in the roadway and heat flow quickly dispersed,which is good for the safe evacuation of personnel.
