The results of measuring the characteristics of the glow of coal flames at the initial moments of ignition under the action of laser pulses of a neodymium laser (1064 nm, 120 μs) are presented. In microparticles of coal grades DG, G, Zh, and K, when the corresponding critical energy densities are exceeded during a laser pulse, the surface ignites and flame propagates at a speed of V~50 m/s. The emission spectra of flames are contributed by the emission of emitted hot coal particles, excited H2* and H2O* molecules, as well as the flame emission arising from the oxidation of carbon (CO*) and carbon monoxide (CO2*) by atmospheric oxygen. Keywords: coal, laser, ignition, flame, volatile substances, degree of coalification, coke residue.
