Limestone mining is done out in theopen. Once studies show the existence of stone at the site, the extraction is made byseparating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made. Thisstudy investigates the existence and quantity of stone at the site and also the economic viability of the process.
Crushed stone is used for concrete aggregate, for road building, and, in the case of limestone, asfluxin 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 blast.

Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earth's surface. Quarrying is a type of mining and is also called as open pit mining or strip mining. When minerals are found profound beneath the surface, a deep mine has to be dug to dig out them. Quarries are normally dug deeper and bigger; awaiting the mineral resource is worn out.
