FIELD: mining.
SUBSTANCE: method includes measurement of concentration of tracer gases in air at outlet from accumulation of coal and rock providing that their background values have been measured. Additionally quantity of water vapour in air is determined and concentration of tracer gases in dry air is determined by formula cc = c / (1 - Fm), where Cc - concentration of tracer gases in dry air, fraction units; C - measured concentration of tracer gas in sample of mine air, fraction units; Fm - fraction of water vapour in unit of mine air, fraction units.
EFFECT: improving efficiency of detection of coal spontaneous ignition processes.
