Open Pit Mining Techniques|Surface Mines|Rock or Mineral,

Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.Open-pit mining - Wikipedia,Open-pit mines that produce building materials and dimension stone are commonly referred to as "quarries." Open-pit mines are typically enlarged until either the mineral resource is exhausted, or an increasing ratio of overburden to ore makes further mining uneconomic.Basics of an open pit mine - Mine Engineer.Com,Several benches may be in operation simultaneously in different parts of, and at different elevations in the open pit mine. Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals.
