Once a mining lease has been awarded to an operator, exploration ( evaluation of the resource) takes place, followed by a planning and development process before excavation or mining begins. The initial task is to gain access to the seam from the surface by some means (shafts, drifts, etc see Access to Seam from surface section for these terms).
Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many coal beds are very near the grounds surface, and about twothirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves.
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 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.
#0183;#32;The mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of American economy and the stages of the mining process have had little fluctuation. However, the process of mining for ore is intricate and requires meticulous work procedures to be efficient and effective. This is why we have
