Based on the coal samples that have been tested thus far, HGI is a good predictor of the quantity of respirable dust that will be generated in a plate mill. The Wharton seam, an anthracite, produced the least amount of respirable dust while the Upper Freeport, a medium volatile bituminous, produced the most.
