METHOD FOR ELECTRICAL VENTILATION OF OPEN-CUT MINE AND AIR MASS IN ADJOINING ZONES

摘要

FIELD: mining industry. SUBSTANCE: method involves generating negative ions by means of corona electrode system to create air flow carrying out contaminated air outside open-cut mine. Efficient ventilation is achieved by creating air flow reaching the extent, at which atmospheric inversion occurs, and due to the fact that corona electrodes have negative electric potential relative to Earth. EFFECT: increased efficiency and improved ecology in minerals mining zones. 4 dwg
