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. Quarry, place where dimension stone or aggregate (sand ...
