A mining operation must either own the land being mined or secure a contract for the “rights” (the legal right) to mine the land. But being free to mine the land is only the beginning. The mining company must invest in equipment and facilities. Beyond that, the mining company must have one or more buyers for its raw materials.
Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is ...
Mine shafts inevitably dropped below water level, so prior to this date, shallow mining was the only way to extract the tin and copper from the ground. The machine driven pump was powered by steam engine and was capable of lifting hundreds of gallons of water per minute from great depths.
