Coal Mining Process

Coal Mining and Processing. 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.

Our Products have stone crusher machine, ore equipment machine, grinding mill, dryer machine, etc.Welcome friends from all over the world. We are always here waiting for your consultation.
