A numerical investigation of the velocity of propagation of a flame in the coal dust suspended in a poor methane–air mixture has been performed with the use of the two-velocity model of a two-phase reactive disperse gas medium. It is shown that the presence of a small amount of methane in the air in which a coal dust is suspended increases the velocity of propagation of a flame in the air suspension. An increase in the size of the coal-dust particles suspended in a poor methane–air mixture ambiguously influences the velocity of propagation of a flame in it: the velocity of a flame in a methane–air mixture containing a small amount of coal particles decreases and the velocity of a flame in such a mixture with a large amount of coal particles increases with increase in their size concentration. The ranges of application of the model of combustion of a coal–methane–air mixture, developed, were determined.
