FIELD: mining, particularly means or methods for preventing, binding, depositing, or removing dust to decrease hazardous influence on neighboring environment zones.
SUBSTANCE: method involves preliminarily treating dust-forming surfaces of tailing pit with 5-25% chalk suspension; treating the surface with sulfuric acid taken in stoichiometric ratio with chalk. The sulfuric acid is aqueous solution having concentration of 5-15% by weight.
EFFECT: possibility to create layer, which prevents dust forming, and increased environmental safety.
