摘要:
The mathematical physics model of mine methane and coal dust explosionpropagation was established in the research, by using continuous phase, combustion, par-ticulate equations of mathematical physics. Based upon the data from mine methanedrainage roadway explosion, and mine methane and coal dust explosion propagation ex-perimental studies, the numerical emulator system of mine methane and coal dust explo-sion software was developed by using prevalent flow simulation platform, which can beused to simulate the explosion accidents process effectively. In addition, the system canalso be used to determine whether coal dust involved in the explosion, and to simulateaccurately the transition from deflagration to detonation in methane explosion, propagationvelocity of explosion shock, attenuation pattern, and affected area of explosion.
