  • Coal seam fire - Wikipedia

    A coal-seam fire refers to natural burning of an outcrop or underground coal seam. Most coal-seam fires exhibit smoldering 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 fine thermal insulation and avoiding rain/snow extinguishment by the crust, underground coal ...
