Coal Mining Processcoal Mining Process Steps

coal | national geographic society,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 above ground..the mining process | introduction | underground coal,once a mining lease has been awarded to an operator, exploration (i.e. 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)..
