Coal - NEED

Coal companies use two methods to mine coal: surface mining and underground mining. Surface mining is used to extract about one-third of the coal in the United States. Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, the topsoil and layers of rock are removed to expose large deposits of coal. The coal is then removed by huge machines. Once ...
