Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil 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.

Dec 27, 2018nbsp018332rock dusters are pressurized pieces of equipment that coal miners use to spray inert mineral dust over highly flammable coal dust. the inert dust helps prevent accidental fires and explosions. shuttle cars and scoops coalminers use electric-powered shuttle cars to transport coal from the coal bed to safer points in the mine.
Dec 21, 2015nbsp018332underground specialized mining equipment such as trucks, loaders, diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. drilling is normally required to place explosive charges to liberate the minerals from the overburden material.
