Guide: Spoil Heaps

Filed under Archaeology, Guide, Industrial Heritage, Landscape Archaeology, Landscape feature, Mining, Spoil Heaps

These are artificial hills made from the unwanted rock, shale and tailings that come up with coal, metal ore, stone or clay when it is being mined or quarried. Because extractive industry is both deep and long-lived, single collieries or pits can generate tens of millions of cubic metres of spoil; pushed out by locomotive, conveyor or tippler wagon and dumped in successive layers, the piles quickly become a distinctive landform.
