quarry | National Geographic Society
A quarry is a place where rocks, sand, or minerals are extracted from the surface of the Earth A quarry is a type of mine called an openpit mine, because it is open to the Earth's surfaceAnother type of mine, a subsurface mine, consists of underground tunnels or shafts The most common purpose of quarries is to extract stone for building materialsExample: A quarry is planned to be working on a rock of Andesite with an estimated production of about 120,000 tonnes per month What is the estimated requirement of explosives Volume of rock blasted per hole = 1935/06 = 3225 m3 So, S X B = 3225/15 = 215 m2 115B x B = 215 B = 43 mH BLASTING IN SURFACE EXCAVATION
