Coal refuse - Wikipedia

Coal refuse (also described as coal waste, coal tailings, waste material, culm, boney, or gob ) is the material left over from coal mining, usually as tailings piles or spoil tips. For every tonne of hard coal generated by mining, 400 kilograms of waste material remains, which includes some lost coal that is partially economically recoverable. Coal refuse is distinct from the byproducts of burning coal, such as fly ash.
