Dec 11, 2018 Coal mining also called colliery is the process of extracting coal from the grounds surface or from deep underground. Coal miners literally raze entire mountain ranges to feed our insurmountable desire for cheap energy. Theres something brutally simple about coal mining.
Read MoreIn surface mining, the ground covering the coal seam the overburden is first removed to expose the coal seam for extraction. The elements of a surface mining operation are 1 topsoil removal and storage for later use, 2 drilling and blasting the strata overlying the coal seam, 3 loading and transporting this fragmented overburden material called spoil, 4 drilling and blasting the ...
Read MoreMining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earths surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nations coal reserves and to produce about three times more coal in one hour than in 1978.
Read MoreMining Process. Sixty million years ago, the area where BNI now mines coal was a vast swamp. Plants died, fell into the water and decayed slowly. Eons later, the climate changed and rivers deposited material over the decaying vegetation. The weight of the overlying material pressed the
Read MoreCoal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining
Read MoreThe two major schools of coal mining are surface mining and underground mining. To qualify for surface mining, the coal seam must lie within 60 metres of the surface. The miners job is to remove all of the overburden the cubic tons of rock, soil and trees above the coal seam -and expose the coal layer for extraction.
Read MoreThe process of contour mining begins with co nstructing roads to access the coal seam elev ation and the top or the mountain. A bench is excav ated in the mountain at the coal seam elevation ...
Read MoreThis is known as the caking process. The quality of the resultant coke is determined by the qualities of the coking coals used, as well as the coke plant operating conditions. Coke quality is largely influenced by coal rank, composition, mineral content and the ability to soften when heated, become plastic, and resolidify into a coherent mass.

Read MoreCoal seams are removed with excess soil and rock placed in an adjacent valley. Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed. Regrading begins as coal excavation continues.
Read MoreBurning coal emits large amounts of carbon dioxide into the atmosphere. Coal is composed almost entirely of carbon, so burning coal unleashes large amounts of carbon dioxide CO 2 into the atmosphere. These emissions have been shown to increase the greenhouse effect in the atmosphere and lead to global warming. Subsurface coal mining is dangerous.
