Quarry. A quarry is a kind of open-pit mine from which rock or minerals are extracted. Quarries are normally utilized for extracting building materials, like dimension stone. Quarries are normally shallower than other kinds of open-pit mines. Quarries are also at times used as filming locations.
Quarries and Open Mines Many of the problems faced by experts in the field of excavation in quarries and gravel pits can be solved by using the data obtained from aerial photographs. This approach provides you with high-quality spatial information reducing the need for field work; thus, the results are faster obtained and the costs reduced.
Open Cast Mines Quarries. A lot of material lies close to the surface, where only a thin layer of soil (called the 'over burden') has to be removed. Where this is done we get the 'open cast mine' and the quarry. Open cast mining usually features a large pit in the ground where the mineral is recovered using large steam cranes.
Surface mines, open pit mines, and quarries differ in important ways. Surface mines are developed to mine a material (often coal) which lies in a narrow bed relatively close to the surface. The bed of material can be removed and the surface restored such that, if done properly, the site can resemble what it was prior to construction.

Open-pit mines that produce building materials and dimension stone are commonly referred to as " quarries ." Open-pit mines are typically enlarged until either the mineral resource is exhausted, or an increasing ratio of overburden to ore makes further mining uneconomic.
