FIELD: mining industry, particularly means or methods for preventing, binding, depositing, or removing dust and preventing explosions or fires.
SUBSTANCE: method involves treating dust-and-gas cloud with finely-dispersed ionized liquid, for instance with water, with the use of sprinkling plants alternately arranged so that ions of liquid spays generated by plants have opposite charges. The sprinkling plants are located outside zone of possible plant damage or are protected against explosion action. Sequence of plant alternation, ionicity, liquid quantity and liquid spraying pattern are determined from tests and calculations based on particular pit or underground mine blasting conditions.
EFFECT: reduced time of particle coagulation on liquid droplets and time of particle precipitation, possibility to reduce dust cloud propagation.
