Assessing and managing spontaneous combustion of coal

Even at the surface, once mined, coal can react with the oxygen in the air to initiate self-heating. This means that spontaneous combustion may occur during any stage of storage, handling and transport between the mine and the site of ultimate coal usage (utility or industry boiler). In addition to the
