Quarrying | MCR Safety

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.

quarry | National Geographic Society

A quarry is a place where rocks, sand, or minerals are extracted from the surface of the Earth. A quarry is a type of mine called an open-pit mine, because it is open to the Earth's surface.Another type of mine, a sub-surface mine, consists of underground tunnels or shafts.. The most common purpose of quarries is to extract stone for building materials.
