Quarry
A quarry is a place where rocks, sand, or minerals are extracted from the surface of Earth.A quarry is a type of mine called an open-pit mine, because it is open to Earth's surface.Another type of mine, a subsurface mine, consists of underground tunnels or shafts.. The most common purpose of quarries is to extract stone for building …
Mining
Deposits mined by open-pit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used; for large mines it is on the order of 12 to 15 metres (about 40 to 50 feet).
