瓦斯爆炸衰减规律和破坏效应

瓦斯爆炸的传播和衰减规律的研究是基于燃烧学、爆炸力学和应用数学等学科从爆炸所在环境出发的应用研究。瓦斯爆炸对构筑物的破坏效应是通过对冲击波阵面上超压、冲击波的作用时间及构筑物所处的位置、构筑物的形状等因素的研究进行的,而瓦斯爆炸的破坏机理和对通风系统破坏效应方面的研究不但可以加深理论而且还可以应用于实践。矿井瓦斯爆炸传播规律、衰减规律和破坏效应的研究成果,对事故防治和调查可以提供重要的技术支撑。

Attenuation and Damage Effect of Gas Explosion

Based on the science of combustion,the explosion dynamics and the applied mathematics,the study of gas explosion spreading and attenuation can be made from the reaction angle between the explosion and the environment.The damage effects of gas explosion on the structures in excavation roadway is to study some factors such as the overpressure in the shock wave front,the action time of shock time,the position of structures,the shape and so on.Through the discussion above,the study about the damage mechanism 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.
