FIELD: mining industry, fighting of endogenous fires in coal mines. SUBSTANCE: holes are drilled in pillar of coal formation. They are arranged before coal formation is mined by mining machine. Point of exit of hole is determined by indicator. Perforated tube is put into hole. Crib with foam-generating grid in the form of sackcloth is positioned around tube. Crib is mounted so that perforated tube is located inside it. Foam- forming solution is fed into hole and inert gas is pumped into boring rod. Foam fill up fallen rock mass and forms curtain. EFFECT: increased efficiency of prevention and fire fighting. 4 cl, 1 dwg
