Outside the mining area for placement and storage in the midwest where the surface topography and coal seams are generally flat it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined in some situations in the eastern united states a coal seam occurring near the top of mountains is

Mine rehabilitation coal 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 has

Coal mining extraction of coal deposits from the surface of earth and from underground coal is the most abundant fossil fuel on earth its predominant use has always been for producing heat energy it was the basic energy source that fueled the industrial revolution of the 18th and 19th
