What is Open Cut Mining? Open cut mining, also known as open-pit or open-cast mining, is a method employed to extract valuable minerals or rocks from the earth. This type of mining is characterised by the creation of a large visible pit or hole in the ground, as opposed to tunnelling into the earth, which is typical of other forms of mining.
2) Open Pit Mining: Since the bauxite mineralization within SMHL mining lease occurs on hill slopes, the mineable ores are extracted on 2-3 meters benches. It is a trucks and excavators loading operation in which 20-30 tons capacity of trucks are utilized to haul ores from mining pit to beneficiation plant.
