FIELD: mining.
SUBSTANCE: method includes long-term treatment of a dust and gas cloud with water vapour during the blast and afterwards. Vapour is produced by a mobile steam generator by introduction of water in it that has been heated previously up to 65-70°C. The steam generator is installed in the place that is safe from the blast and is directed along with the wind. Besides, prior to blasting, atmosphere above the blasting area undergoes treatment.
EFFECT: higher efficiency of dust suppression, manoeuvrability of plants.
