FIELD: mining industry, particularly for fire-hazardous mineral bed development.
SUBSTANCE: method involves provision of track and flank drifts, conveyer and vent drifts directed along extraction pillar from both sides thereof and split furnace; forming additional drifts with antipyrogen compositions over the full perimeter thereof and securing thereof with wooden supports; filling additional drifts in recessive order with fine coal particles previously treated with steam; sealing additional drifts with partitions spaced apart a distance equal to daily face advancing.
EFFECT: increased safety of mining works.
