• How Is Coal Extracted? Reference

    Coals mines use surface mining for coal deposits buried less than 200 feet underground. In this type of mining, giant machines remove top-soil and layers of rock to expose large beds of coal. After coal extraction, the topsoil is replaced so that the area can be reused for croplands, wildlife habitats, recreation or offices.
