The quarrying process consists of separating large blocks, sometimes called loafs, from the surrounding rock. These blocks may be 6 metres high by 6 metres deep and 12 to 18 metres (about 40 to 60 feet) long, and they may weigh in the range of 1,200 to 2,000 tons. (Such large blocks are subsequently divided into mill blocks weighing 15 to 70 tons.)

Quarrying Basics

Quarrying is quite simply the extraction of natural resources from the earth, usually from some form of surface working or quarry site. Quarries produce a range of useful materials, including limestone, dimension stone and rock. In Australia, the most common materials extracted are construction aggregates such as crushed rock, sand or gravel.
