Spontaneous fracture of coal

Douglas V. Keller; Clay D. Smith

Abstract Examples of the spontaneous fracture of various United States coals using several different solvents with solubility parameters in the range 9–15 ( cal/cm 3 ) 1 2 [ 18.5–30.7 ( J/cm 3 ) 1 2 ] were used to identify a swelling—fracture relation which predicts the final maximum particle size of the reacted coal. The effects of liquid ammonia were of particular concern. The model appears consistent with the observed effects of various liquids, including water, on various coals in bench and pilot-plant scale. A distinct advantage for the unique separation of pyrite or other mineral matter was not observed.
