Attenuation and Damage Effect of Gas ExplosionQU Zhi-ming1, WU Hui-ge2,HAO Gang-li2,GAO Hong-jun1,WANG Xiao-li3(1. School of Civil Engineering, Hebei College of Engineering, Handan056038,

;. Extension Department, Handan Association of Science and Technology, Handan056002, China)bstract:Based on the science of combustion, the explosion dynamics and the applied mathematics, the study of gas explosionspreading and attenuation can be made from the reaction angle between the explosion and the environment. The damage effects of gasexplosion on the structures in excavation roadway is to study some factors such as the overpressure in the shock wave front, the actiontime of shock time, the position of structures, the shape and so on. Through the discussion above, the study about the damage mech-anism and damage effects on ventilation system can be put into theory research and practice. The research findings on the spreading,attenuation and the damage effects during gas explosion will technically support the accidents��prevention and cure and investigation.Key words:gas explosion;attenuation;damage effect;excavation roadway;shock wave
