How Is Coal Extracted? - Reference
2020-4-9 According to the World Coal Association, more than 6,185 million tonnes (Mt) of hard coal was mined from coal mines around the world as of 2012. 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.
