2021-3-25  Underground coal gasification (UCG) is the process of converting a coal seam into synthesis gas in-situ by injecting sufficient air/oxygen/steam mixture to gasify the coal at a high temperature. The purpose of UCG is to access and harvest the energy contained within the solid fuel underground, without applying conventional mining methods.
