FIELD: mining.
SUBSTANCE: invention refers to mining and may be used for fine dust control during open mining of mineral deposits with blasting operations. Proposed dust suppression method during blasting operations consists in moistening of blasted unit with fluid from irrigation plant before blast. As irrigation fluid, biohumus aqueous solution is used, which concentration in solution is 10-25%. The specified solution is used for treatment of blasted unit after charge and further well stemming to mounting of blasting circuit.
EFFECT: increasing dust suppression efficiency.
