Axial Flow Fan Use At San Manuel Mine, Kuda R. Mutama, Dave P. Pelletier Jun 1999

Axial Flow Fan Use At San Manuel Mine, Kuda R. Mutama, Dave P. Pelletier

U.S. Mine Ventilation Symposium

A case study is presented for the use of multiple axial flow main fans as the principle source of the primary mine ventilation system for a large multi level mine. Formerly owned by Magma Copper, BHP Copper Inc.'s San Manuel Mine is a large underground block caving copper mine which started producing copper in 1955. The San Manuel Mine produces over 50,000 tons per day sulfide copper ore. The total airflow into this mine is approximately 800 m3/s (1,600,000 cfm). Providing adequate ventilation has been a very challenging experience as new, deeper levels are ...
