Quarrying is theprocess of removing rock,sand,gravel or other minerals from the ground in order to use them to produce materials for construction or other uses. So, a quarry is any such working on the surface of the earth where minerals are extracted. …
[email protected]Sand,gravel, andcrushed rock quarries employ standard surface-mining techniques. Crushed stone is used for concrete aggregate, for road building, and, in the case of limestone, as flux in blast furnaces and for chemical applications. The quarrying technique consists of drilling and blasting to fragment the rock. A large number of charges are fired at one time, producing up to 20,000 tons of broken stone in one …
