Elemental Composition of Coal Mine Dust.
MISSING :25 pages
The need for elemental-analysis information on coal mine dust for use in health and safety research prompted this study by the Bureau of Mines. Neutron-activation and x-ray fluorescent techniques were used to obtain five-element analysis (silicon, aluminum, iron, calcium, and magnesium) on 444 samples from 68 coal mines in 10 states. From these analyses, the average composition of the dust in coal mines was determined.
