Abstract
Several mathematical models of spontaneous heating were developed in support of the U.S. Bureau of Mines' research program directed toward the prevention of spontaneous heating in coal piles and/or gobs. Reaction kinetics associated with the oxidation of coal were used in a transient thermal transport model of spontaneous heating to estimate the thermodynamic stability of a coal pile of uniform porosity and particle diameter under the following assumptions: (1) a spherical zone within the coal pile is initially at a specified elevated temperature, and (2) an ambient oxygen supply is maintained in the pile.
