Crushed stone is used for concrete aggregate for road building and in the case of limestone as flux in blast furnaces and for chemical appli ions. 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 20000 tons of broken stone in one blast.
