Is Mining Coal Opencast Underground

3.6.4 Losses During Mining. Mining of coal is undertaken broadly using two methods: surface and underground. In the case of underground mining, losses are high compared with those of opencast mining; the main causes of these losses are enumerated in the following subsections. 3.6.4.1. Opencast Mining

    Sep 12, 2010 Coal is mined by two methods – surface or ‘opencast’ mining and underground or ‘deep’ mining. By Prasetianto Mangkusubroto. The choice of mining method is largelydetermined by the geology of the coal deposit. Underground mining currently accounts for about 60% of world coal production, although in several important coal producing

    What is the difference between opencast & underground mining?

    Open cast mining is the removal of rocks or sediments that contains minerals, with economically important elements. The advantages of open cast mining: • More cost effective, than shaft mining. • The working conditions are safe for miners, there is no risk of toxic gases or cave ins. • Trucks and mining machinery can move around freely

    When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which

    Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining, the later term being commonly used in the U.S.A. for opencast mining of coal. The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip mining
