Combustion and detonation waves in hybrid systems of gas mixtures CH 4 /air with suspensions of coal particles 1–200 μm in size in a vertical shock tube (70 mm in diameter and 6.75 m long) are studied experimentally. The structure and parameters of the waves in gas mixtures without coal dust and in the same mixtures containing suspensions of a coal powder with a mean-volume density of 23–534 g m –3 are compared. XRD patterns of the coal powder are analyzed.
