Dust control and ventilation at Ontario mines
Depth of mines range from few hundred to 8000 ft, approximately; primary products of underground group are asbestos, gold, silver, cobalt, copper, nickel, iron, uranium, talc, fluorspar, gypsum and salt; organization to prevent exposures to dust; permissible limits of air dustiness; adequate use of water to allay dust in mining, coupled with good ventilation of operations underground and on surface.
