drift mining. drift mining is a process of accessing precious geological material, like coal, by cutting into the side of the earth, rather than tunneling directly downwards. drift mines have flat entries into the coal seam from a hillside. drift mines are different from slope mines, which have a tending opening from the surface to the coal vein.
In surface mining, all of the rock from the ground surface to the top of the seam is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use with underground mining, in contrast, a series of openings is made from the surface to the

morgan mccrory sustainable environments assignment coal mining in appalachia coal mining is the process of extracting coal from the ground. It is valued for its energy content, and has been widely used to produce electricity. mountaintop removal is mining that is prevalent in appalachia. the operation of mountain top mining there has become contentious.
mar 01, 2021 the process of extracting coal from the ground can be conducted via two methods: surface mining underground mining both these techniques include different types of mining, but all them use giant machines to remove coal from under the ground.
coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.in addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.
mining 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.
