Everything You Need To Know About Open Pit Mining

Nov 01, 2018 Open pit mining results in waste products collected from all sides and the bottom of a pit which leaves a huge canyon-like hole. These "quarries" are open pit mines that produce dimension stone and materials used in buildings and construction. Mining usually continues until they have realized all available mineral resources.

Open-pit mining

Open-pit mining, also known as mega-mining, open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful
