Optimization Of The Ventilation System At Kidd Mine Of Falcon Bridge Limited, Josef Sedlacek

U.S. Mine Ventilation Symposium

Kidd Mine is the single largest producing base metal mine of Falconbridge Limited. Approximately 3 million tonnes of zinc-copper ore is produced annually. The present ventilation system, designed some 30 years ago, uses a multitude of intake and exhaust fans, in a series-parallel configuration, to move 925 m3/s (2,000,000 cfm) through the mine. The system, owing to the ever increasing depth of mining, has reached its limitation and has become cumbersome to maintain. It was recognized that with the mine progressing from the original depth of 855 m (2800 ft) to the current depth of 2070 ...
