nov 05, 2013 mining methods. coal is mined by two. methods: surface or opencast mining underground or deep mining. the choice of mining method is largely determined by the geology of the coal
most underground coal is mined by the room and pillar method, where by rooms are cut into the coal bed leaving a series of pillars, or columns of coal, to help support the mine roof and control the flow of air.generally, rooms are 2,000 feet wide and the pillars up to 300 feet wide. At least feet of coal was left between an underground mine and the surface, if not the surface had a higher
the overall coal mining process consists of several sequential stages: exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; analysis and selection of a mining plan; securing the markets; developing the mine; extracting the coal; processing the coal if necessary; and decommissioning the mine and releasing the property for post-mining
the elements of a surface mining operation are topsoil removal and storage for later use, drilling and blasting the strata overlying the coal seam, loading and transporting this fragmented overburden material drilling and blasting the coal seam, loading and transporting the coal, backfilling with spoil and grading, spreading top soil over the graded area, establishing vegetation and ensuring control of soil erosion and water quality, and

coal mining, extraction of coal deposits from the surface of earth from underground. coal has been used since the bronze age, 3,000 to 4,000 years ago, and was the basic energy source that fueled the industrial revolution of the and centuries.
surface coal mining generally involves the following sequence of unit operations: clearing the land of trees and vegetation, removing and storing the top layers of the unconsolidated soil drilling the hard strata over the coal seam, fragmenting or blasting the hard strata with explosives, removing the blasted material, exposing the coal seam, and cleaning the top of the coal seam, fragmenting the coal seam, as required, by drilling and blasting, loading
jan 25, 2018 underground mining is more widely used to extract coal compared to opencast mining, as many coal seams are said to be found deep below the earth surface. the underground mining includes six type of mining methods that include longwall mining, continuous mining, room and pillar mining, blast mining, shortwall mining and retreat mining.
