Underground Coal Gasification is the conversion of solid Coal to gas in-situ by heating the coal and  injecting  oxidants  air/oxygen  to  cause  the  gasification  by  partial  combustion  instead  of complete combustion of coal. UCG is the promising technology having a lot of health, safety and environmental  advantages  over  the  conventional  mining  techniques;  the  major  motivational aspects of UCG involves increased worker  health & safety by using no man  underground, no surface disposal of ash and coal tailings, low dust and noise pollution, low water consumption, larger coal reserves exploitation, and low Volatile organic components, methane and greenhouse gases emission to atmosphere.
