The Cerrejón mine has identified fires in its coal production seams for a few years in its operation. Fires are produced as a result of spontaneous combustion phenomena. Coal spontaneous combustion is a phenomenon that occurs naturally during coal oxidation when exposed to atmospheric conditions, du...
