Quarrying

People have been mining the earth for ages.  During the Stone Age, one of man’s greatest innovations was learning to chip away limestone for making cutting tools, hammers, and hand axes.

The Egyptians took stone quarrying to the next level by being the first to saw rock and drill into rock.  The Romans quarried and cut stone with their own innovative stone cutting techniques. One of those innovative techniques is called plugging and feathering.

Across the US, there are over 10,000 quarries, which means there are many workers requiring newbb电子. A quarry is a place, most often recognized as a dip pit, from which stone and rock is excavated from the ground. Today's quarrying industry produces crushed stone, granite, marble, sand, and gravel. Most of these minerals are close to the surface, making surface mining or opening pit mining the primary form of mining.

The type of quarrying ultimately depends on the type of product removed:

• Dimension Stone Industry

  Granite, marble, limestone, and slate. This type of quarrying involves cutting and shearing blocks of stones into specific dimensions. Powerful equipment for cutting and sawing are needed. These stones help build walls, floors, headstones and monuments.

• Aggregate Industry

  Sand, stone, and gravel. These materials are utilized in virtually every building material. Explosives and blasting are the primary mining methods used in aggregate mining. Aggregate materials are an absolute must for constructing roads. Society as we know it today would not exist without aggregate - no highways, no airports or no stadiums. Portland cement requires sand, gravel, and limestone.

Quarried rock helped the Romans build
innovative aqueducts for supplying water to Rome.

Stones final end use may be different from Stone Age man's use, the Egyptian's use of rock and stone or the Roman's use of rock and stone. However, rock chipping continues on in our modern world. To highlight this point, the BLS reports the quarrying industry workforce consists of 3% rock splitters.
