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 …

The quarrying process is also known as "extraction.". This procedure consists of removing blocks or large pieces of stone from a previously identified geological deposit. The different methods used to quarry or extract the limestone depends on the specific properties of the limestone deposit itself, including density, bedding planes, and depth.

Extraction and processing. Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.. The …
