Injury study on impact current of gas explosion in coal mine

YANG Shu-zhao,JING Guo-xun,JIA Zhi-wei ( School of Safety Science & Engineering,Henan Polytechnic University,Jiaozuo 454003,China)  
Combined with the theory of the energy and gas explosion dynamics,the attenuation law of impact current in excavation roadway was deduced during gas explosion. The deduction shows that the impact current of gas explosion is inversely proportional to the square root of the propagation distance and the roadway section,and in direct proportion to the square root of the accumulated volume of gas comparing the analysis between experiment and deduction. On the analytical foundation,built up impact current of air to hurt model. It is concluded that the theoretical data is fairly close to that of the experiment,which proves that the deduction of the impact current of gas explosion attenuating with the propagation distance is reasonable.
