Highwall mining is a proven technology in USA and Australia to extract the blocked coal in thin non-workable seams and the coal blocked in the highwall of opencast mines. In USA, highwall mining contributes about 4.0 % share of total coal production. In India, the highwall mining is in the nascent stage.

Opencast Mining Opencast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow. Underground Mining Longwall Mining (Coal Shearer) Longwall mining is a form of underground mining where a long wall of coal is mined in a single slice (typically 0.6–7.0 m thick).

Due to the large scale extraction of near-surface coal resources by opencast mining, near-surface coal resources will be depleted in future. ...

The underground method is suitable for. extraction of deeper coal seams, whereas opencast method is suitable for shallow coal seams. However, due to less production cost, mechanisation, and less ...

Shortwall mining currently accounts for less than 1 percent of deep coal production, involves the use of a continuous mining machine with movable roof supports, similar to longwall. The continuous miner shears coal panels 150-200 ft wide and more than a half-mile long, having regard to factors such as geological strata. Retreat mining

In opencast mining these machines are very important links for continuous excavating, transporting and discharging activities especially when mining and dumping areas are spread apart over significant distances. The belt wagons help save on overall investments and operating costs which otherwise would be substantially higher due to the need to ...

Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.
