The time in which the mine remains operational, from startup to mine closure. The average rate at which mining takes place within a certain time period (normally per annum). The mining rate can refer to coal extracted per annum or to the waste stripped per annum. A mining practice in which the higher quality coal is mined first in the mine life.
''The two main methods of extraction are opencast mining and underground mining.'' ''Exploration for hydrocarbons has resulted in drilling to basement in many basins and, where coal seams occur close to the surface, opencast mining has exposed the strata.''
The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface mining is more common.
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 ...
