Quarry mining Britannica

Sand, gravel, and crushed 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

Quarrying of Stones: Its Methods, Selection of Site

The process of extraction of suitable stones from their natural rock beds or layers is commonly called Quarrying of Stones. It differs from the mining of ores of metals in that whereas quarrying is an operation carried out entirely on the surface, mining involves digging below the ground, sometimes at considerable depth.

Quarrying processes SpringerLink

This process refers to the removal of rocks from a cliff or wave-cut platform from their in situ position by wave action. Continued wave attack on a cliff or platform edge exerts tremendous hydraulic pressure and erosive force along lines of weakness, often bedding and joint lines.
