In surface mining or quarrying, oversize boulders cause delays in loading operations. Boulders or oversize rocks have to be lifted out of the muckpile during digging and set aside for secondary breakage. In underground mines oversize may cause hangups in the chutes and orepasses. Oversize rocks may be broken by hydraulic impact breakers or

Most surface mines follow the same basic steps to produce coal. First, bulldozers clear and level the mining area. The topsoil is removed and stored for later use in the reclamation process. Many small holes are drilled through the overburden (dirt and rock above the coal seam) to the coal seam.
Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the topsoil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted.
