Coalseam fire Wikipedia
A coalseam fire is a natural burning of an outcrop or underground coal seamMost coalseam fires exhibit smoldering combustion, particularly underground coalseam fires, because of limited atmospheric oxygen availability Coalseam fire instances on Earth date back several million years Due to fine thermal insulation and the avoidance of rain/snow extinguishment by the crust, undergroundCrusher wikipedia crusher is a machine designed to reduce large rocks into smaller rocks gravel or rock dust crushers may be used to reduce the size or change the form of waste materials so they can be more easily disposed of or recycled or to reduce the size of a solid mix of raw materials as in rock ore so that pieces of different positionRock Crusher Germany Mining
