For starters, let’s distinguish between mining and quarrying. MiningĀ involves taking an economically useful material from the ground. Substances that are mined include ores, coal, evaporites, and precious stones and metals. QuarryingĀ is the cutting or digging of stone, and related materials, from an excavation site or pit and it usually leaves behind a large hole in the ground.[efn_note]”AĀ quarryĀ is a place from whichĀ dimension stone,Ā rock,Ā construction aggregate,Ā riprap,Ā sand,Ā gravel, orĀ slateĀ has been excavated from the ground. A quarry is the same thing as anĀ open-pit mineĀ from whichĀ minerals are extracted.Ā The only trivial difference between the two is that open-pit mines that produce building materials and dimension stone are commonly referred to as quarries.”[/efn_note]
