Mining is the removal of minerals from Earth's crust. Quarrying is the mining of stone, or rock used mainly for building. A quarry is a hole or a pit in the ground from which workers remove stone. During quarrying, workers cut or blast stone into smaller pieces. These smaller pieces of stone are easier to handle and can be used to make many things.
Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types (mines and caves). For thousands of years, only hand tools have been used in quarries. In the 18th century, the use of drilling and blasting operations was mastered.

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.
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. The broken stone is crushed into smaller pieces that are separated into uniform classes by screening. Read More on This Topic mining: Quarrying
