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.
