Coal fires - Global Energy Monitor

Coal fires occur in operating coal mines, abandoned coal mines and waste coal piles. They sometimes start because of a nearby blaze, but they can also ignite through spontaneous combustion: certain minerals in the coal, such as sulfides and pyrites, can oxidize and in the process generate enough heat to cause a fire.
