FIELD: fire safety.
SUBSTANCE: method of prevention of endogenous fires break-out is proposed, comprising treatment of the surface of coal. At that the surface of coal is preliminary treated with adhesive fluid, and then the microcapsules of temperature-sensitive and water-insoluble material with a diameter from 20 to 5000 microns are sprayed under pressure, which contain an inhibitor in an amount of 50-95% and easily opened at temperatures above 45 degrees.
EFFECT: neutralisation of a fire source at the time of its occurrence and blocking of propagation of already existing fire.
