• Variability of Natural Dust Erosion from a Coal Pile

    AbstractA study of fugitive dust emissions from a pile of crushed coal revealed that, in addition to dust being emitted into the atmosphere during periods of pilemanagement (human) activity, it is also emitted during periods without human activity. This "natural" emission in itself is not surprising given past work on wind erosion of particulate matter from aggregate piles.
