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 ...
