A Fundamental Study on Coal Dust Cloud Auto Ignition and Methane Flammability Limit in Ventilation Air Methane VAM Mohammed J Ajrash Jafar Zanganeh Daniel Eschebach and Behdad Moghtaderi Abstract The Deflagration and explosion of dust cloud and flammable gases are a major concern in process industry AOver the past century the coal mining industry experienced a large number of explosions leading to a considerable loss of life Research was directed at preventing the accumulation of methane through good ventilation practice eliminating frictional sparking by the use of water minimising dust generation and dispersal and using stone dust to inert coal dusts to prevent coal dust from

In the coal mining industry a methane explosion can initiate a coal dust explosion which can then engulf an entire mine pit As a precaution incombustible stone dust may be spread along mine roadways or stored in trays hanging from the roof to dilute the coal dust stirred up by a shockwave to the point where it cannot burn Mines may also Spontaneous Combustion Dust Explosion Those cement plants which use coal/lignite as fuel need to have fairly large coal storage yards Adequate care needs to be taken while storing the coal as some types of coal and lignite are susceptible to spontaneous combustion and there are also possibilities of dust explosion involving coal dust Lignite/
