Mining Operations partha sharma

Mining coal has a tremendous environmental impact, so extracting the energy out of coal while it still is in the ground makes a lot of sense. Gasifying coal below ground eliminates the need to mine the coal. Underground coal gasification (UCG) has the potential to provide a clean convenient source of energy from coal seams where traditional mining methods are either impossible or uneconomic to develop. Underground Coal Gasification (UCG) or the use of geo-reactors offers tremendous potential to clean up coal energy and enable economic access to stranded coal deposits.
