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.
In this situation continuous mining machines are used in the "roomandpillar" method. In the 1950s, a new underground mining method appeared in Europe. It is called a ''longwall mining'' method that applies laser technology. Today, it is widely used by coal mining companies in the world.
