井下烟道在巷道火灾中的作用数值模拟
Numerical Analysis of Underground Flue Effect on Mine Roadway Fire
摘要
Abstract
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.关键词
