Abstract
The mathematical physics model of mine methane and coal dust explosion propagation was established in the research, by using continuous phase, combustion, particulate equations of mathematical physics. Based upon the data from mine methane drainage roadway explosion, and mine methane and coal dust explosion propagation experimental studies, the numerical emulator system of mine methane and coal dust explosion software was developed by using prevalent flow simulation platform, which can be used to simulate the explosion accidents process effectively. In addition, the system can also be used to determine whether coal dust involved in the explosion, and to simulate accurately the transition from deflagration to detonation in methane explosion, propagation velocity of explosion shock, attenuation pattern, and affected area of explosion.
