Coal cleaning was largely developed to remove ash-forming minerals from coking coal. The coke-making industry has long recognized the benefits of clean coal, and most of the coal used by this industry is cleaned. On the other hand, only 15-20% of the coal consumed by the electric utility industry is cleaned and

Airborne coal dust is also explosive, given the right particle size, concentration, and ignition source. Bureau of Mines studies have shown that ignitable airborne coal dust concentrations start on the order of 50g/m3 (0.05 oz./ft3) [5,6]. The most explosive coal dust size in air is below 75 nm (—200 mesh) [5,6]. Airborne coal dust
