Open Pit Mining
Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Figure 8.8. Open-pit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.
Characterization and environmental sustainability of open pit coal mine
In India, this demand is fulfilled majorly (93%) by surface mines or open pit mines that simultaneously produces a vast amount of coal mine overburden (OB) or waste rock. This OB constitutes a mix of sandstone, shale, colliery discard, fragments of igneous and metamorphic rocks, mudstone, and claystone [1], [2] .
MINING Equipment List Mining Tools Names + Underground + Open pit
Underground Mining equipment list. Soft rock mines, such as coal, do not require the use of explosives for extraction. These rocks can be cut with the mining tools provided by modern technology. Soft rocks are also salt, potash, and bauxite. In hard rock mines, extraction is carried out by drilling and blasting.
