Research on theoretical spreading law of shockwave of coal dust explosion in general air area in laneway corner
摘要
Abstract
The spreading theoretical law of shockwave of coal dust explosion is the pvemise and poundation to study the mechanism injury and damage.This paper analyzed the theoretical spreading law in the laneway corner based on the theory of flow dynamics and explosive dynamics.According to the spreading law of oblique shock wave,this paper is to set up the mathematical model of the shockwave spreading of coal dust explosion in general air area in laneway corner and deduce the corresponding equation.By using the suddenly jump parameters of wave front to represent the shockwave,the paper derived the simplified equation of spreading law in the laneway corner.Research indicates that the attenuation coefficient of shockwave of coal dust explosion increase with the initial shockwave pressure and angle of the laneway corner rising.By contrastive analysis of the spreading law and experimental results,the results of theoretical derivation were ueripied.关键词
