| - A spoil tip (also called a spoil bank, boney pile, gob pile, bing, batch or pit heap) is a pile built of accumulated spoil - the overburden or other waste rock removed during coal and ore mining. These waste materials are typically composed of shale, as well as smaller quantities of carboniferous sandstone and various other residues. Spoil tips are not formed of slag, but in some areas they are referred to as slag heaps. Spoil is distinct from tailings, which is the processed material that remains after the valuable components have been extracted from ore.

| - A spoil tip (also called a spoil bank, boney pile, gob pile, bing, batch or pit heap) is a pile built of accumulated spoil - the overburden or other waste rock removed during coal and ore mining. These waste materials are typically composed of shale, as well as smaller quantities of carboniferous sandstone and various other residues. Spoil tips are not formed of slag, but in some areas they are referred to as slag heaps. The term "spoil" is also used to refer to material removed when digging a foundation, tunnel, or other large excavation. Such material may be ordinary soil and rocks, or may be heavily contaminated with chemical waste, determining how it may be disposed of. Clean spoil may be used for land reclamation. Spoil is distinct from tailings, which is the processed material that remains after the valuable components have been extracted from ore.
