Ventilation of Development Headings at the Sullivan Mine

This paper describes the methods used for the ventilation of raises, sublevels and drawholes at Cominco's Sullivan mine. The problems involved in ventilation during blasting, drilling and scraping operations are first re-viewed, and then the air mover, a piece of equipment developed at the Sullivan mine, is described. The design of this device is discussed, along with the operating procedures used. Some figures are given to show the effectiveness of the method. THE Sullivan mine, located at Kimberley in the southeast corner of British Columbia, is owned and operated by The Consolidated Mining and Smelting Company of Canada Limited. Current daily production is approximately 10,000 tons. The mine is developed by sixteen levels over a vertical range of 2,000 feet. The total ventilation requirements, which amount to approximately 1,000,000 cubic feet per minute, are handled through a network of fresh air intake and foul air exhaust circuits. In addition to the many development and production headings, there are three crushing chambers and an extensive conveyor system which must be ventilated.
