Floor dust erosion during early stages of coal dust explosion development [PDF]
International Journal of Mining Science and Technology, 2019 An ignition of methane and air can generate enough air flow to raise mixtures of combustible coal and rock dust. The expanding high temperature combustion products ignite the suspended dust mixture and will continue to propagate following the available ...

Colliery Explosions and Coal-Dust [PDF]
Nature, 1880 ACCEPTING Mr. Galloway's view that in many mines the extent and destructiveness of colliery explosions are due to the distribution of coal-dust in the air, may I suggest the possibility of preventing the explosion from spreading beyond the sphere of the fire-damp by sprinkling the floors throughout, at certain regular interval, with mineral oil?
