Explosion Prevention in United States Coal Mines

2012-8-30  Another explosion hazard in underground coal mines is fine coal dust which can be dispersed and ignited by a methane gas ignition. This adds fuel to the ignition, thereby increasing the pressure and heat released by the explosion. 2. Explosion Protection Philosophy To protect underground mines from methane gas and coal dust explosions, various

A physical description of coal mine explosions. Part II ...

1979-1-1  The main theme of this paper was that the essential fluid dynamics behavior that is characteristic of coal mine explosions cannot be simulated in small ducts or by burners. While it is true that the same chemical processes are going on at the same rates, their relative effect may be less significant in a large scale explosion, where there is plenty of time for mixing and reaction because the
