Respirable Dust Generation: Comparison of Continuous and Conventional Mining Methods When Excavating Rock in Coal Mines.
MISSING :9 pages
The U.S. Bureau of Mines recently conducted an investigation into the amount of respirable and quartz dust generated while mining rock in coal mines by continuous and conventional methods. The study was made at two mines that use both continuous and conventional mining. Results show that continuous mining produces 1.2 to 3 times more respirable dust, and 6.7 To nearly 15 times more quartz dust than conventional mining.
