A quarry is typically defined as being a surface excavation for the production of rock as the principal product. As such, it differs from an open cast, open-cut, surface or open-pit mine in that the rock itself is the valuable commodity, rather than a specific mineral within the rock mass. Quarrying is used mainly in the production of ...

Aggregate is mined from the earth, either dug out of pits or blasted out of quarries. This process has many significant environmental impacts. [1] Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath. Not only does this lead to a loss of existing animal ...
