摘要：

The measured thresholds (H-cr) and kinetic characteristics of the ignition of the volatile substances and the coke residue of low-rank coal under the action of the pulses of a neodymium laser (1064 nm, 120 mu s) are reported here. The ignition of volatile substances was observed in microsecond (H-cr = 0.3 J/cm(2)) and millisecond time intervals (H-cr = 1.2 J/cm(2)). The combustion of the coke residue occurred in a time interval of 30-100 ms (H-cr = 2.6 J/cm(2)).
