The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can sustain. There are many advantages in openpit mining method namely:Full visualization of exposed orebody and negligible ore loss,
mining: Surface mining It has been estimated that more than twothirds of the worlds yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a ''pit'', and
OpenPit Mining: Removal of rock and soil creating a vast pit where ore can be extracted. Mountaintop Removal Mining: Removal of mountain tops with explosives. Land made flat after reclamation. Highwall Mining: A continuous miner cuts holes horizontally into the coal formation. Quarrying: A place where dimension stone or aggregate is mined.
