A coal-seam fire is a burning of an outcrop or underground coal seam. Most coal-seam fires exhibit smouldering combustion, particularly underground coal-seam fires, because of limited atmospheric oxygen availability. Coal-seam fire instances on Earth date back several million years. Due to thermal insulation and the avoidance of rain/snow extinguishment by the crust, underground coa

Coal fires Global Energy Monitor
Coal fires. 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. [1] Coal fire
Spontaneous Combustion an overview ScienceDirect Topics
Sometimes air locks are installed between the feeder and the coal mill and these tend to cause coal hold up, which can result in loss of coal feed to the mill, thus introducing an explosion risk. A large pile of coal will almost inevitably catch fire and burn, and barges of coal must be transported and unloaded quickly or the barge will
