Quarrying Methods. Quarrying methods are classified differently. It is convenient to divide them under two main headings. namely, quarrying without blasting and quarrying by blasting. 1.1 Quarrying of Stones without Blasting. In these methods, blocks of rocks are broken loose from their natural outcrops by men. In this method, men …

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 blast.
