【摘要】:以火災動力學軟件FDS(Fire Dynamics Simulator)在礦井巷道火災中模擬方法為主線,建立了巷道中有無頂棚煙道的研究模型,對發(fā)生火災時巷道溫度場以及煙氣變化情況進行探究。通過實驗分析表明,設置頂棚煙道對巷道火災煙氣流動起到一定的抑制和疏導作用;隨著風速增加,巷道中溫度明顯下降,熱流快速分散,利于人員安全疏散。
[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.
