12 Environmental Effects of Coal Mining Environment 911AN IMPROVED INVENTORY OF METHANE EMISSIONS FROM COAL

Coal is a fossil fuel that s burned to generate electricity and heat or liquefied to produce gas and diesel fuel Coal begins as plant matter that s trapped underground for centuries and over time becomes petrified due to lack of exposure to airMethane emitted from underground surface and abandoned coal mines is often released from both the coal seams and surrounding strata In longwall mines the zone of disturbance can
