Abstract
Different coals preserve characteristic acoustic features of failure in self-sustained burning irrespective of the ignition cause. Phenomena which promote coal disintegration in heating are described. The failure mechanism of live coal in a seam is set, and appropriateness of the rating of the typical acoustic features revealed in coal burning on a lab scale is proved on this basis.
