As with area mining, it is necessary to remove the vegetation and remove the overburden to gain access to the coal seam. There are two ways to handle the removed overburden: haul it all the way down the hill and put it into a chosen valley in horizontal layers; or to place it in the void of the cut, where the coal has been already removed.
