To reduce the fire hazard caused by spontaneous combustion in the gob, a computational fluid dynamics (CFD) study is being conducted by NIOSH to simulate the spontaneous heating of coal in the area. Researchers developed a CFD model of the spontaneous heating process in a two-longwall-panel district using a bleeder ventilation system with a stationary longwall face. The spontaneous heating was modeled as the low-temperature coal oxidation in the gob using kinetic data obtained from previous Bureau of Mines laboratory-scale spontaneous combustion studies.
