Coal is mined by two methods

12/09/2010Coal 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 countries surface mining is more common

Coal mining

Coal mining is the process of getting coal out of the ground It is part of the mining industry Coal is used as a resource for making electricity Surface mining is done when the coal is near the surface Coal miners remove the soil above the coal The coal can then be removed without the coal miners having to go deep underground

Coal Formation

Coal beds consist of altered plant remains When forested swamps died they sank below the water and began the process of coal formation However more than a heavy growth of vegetation is needed for the formation of coal The debris must be buried compressed and protected from erosion

Strip Mining: A Destructive Way of Coal Extraction

12/03/2017The process of strip mining also lowers groundwater levels around the mine In order to remove the coal vast quantities of groundwater are pumped out of the mine and as a result surrounding ecosystems and farmland may become drier and erosion may start to change the landscape Strip mining also uses significant amount of water to suppress dust

what is process of mining coal

Strip mining is the practice of mining a seam of mineral by first removing a long strip of overlying soil and rock (the overburden) It is most commonly used to mine coal and lignite (brown coal) Strip mining is only practical when the ore body to be excavated is relatively near the surface

Negative Effects of Coal Mining

The effects of mining coal on the environment There are 2 ways to mine coal – Strip Mining and Underground Mining – both ways have their own impact to the environment and health We know it but coal is such a cheap energy source that we don't want to let go of it The negative effects of coal mining cannot be disputed:

Coal

Underground mining sometimes called deep mining is a process that retrieves coal from deep below the Earth's surface—sometimes as far as 300 meters (1 000 feet) Miners travel by elevator down a mine shaft to reach the depths of the mine and operate heavy machinery that extracts the coal and moves it
