Coal Gasification - an overview | ScienceDirect Topics
Underground coal gasification (UCG) is a process by which coal is converted to useful gases in situ without the need for mining. The gases can subsequently be used to produce heat, generate power or synthesize a variety of stone products. UCG is realized through circulating gasification agents (air or oxygen and water) into a coal seam.
