Ventilation - Basic Mining Process ... - .

To do this at least two connections between seam and surface are required and large fans are connected to one of these. These are primarily exhaust fans which suck air into the mine from the surface via the other connection(s), through the roadways to where mining operations are being carried out and back to the surface through the exhausting fan(s). A few mines do use intake or "forcing" fans ...asbestos in mining exhaust fans - Animal .Asbestos In Coal Mining Ventilation Fans asbestos in coal mining ventilation fans KAMY is the worldwide leader in manufacturing hydraulic cutters, road headers, tunnel support systems, and other specialized machinery used in the tunneling, mining, and construction industries.MINE VENTILATION SYSTEMSMine Fan Main Levels R R D D 1 2 3 Figure 9-1.
