An Overview of the Chinese UCG Program
Data Science Journal, 2007 Coal is the dominant source of energy in China, but about 50% of the coal resource is left underground unmined. Because of this, the "long-tunnel, large section, two-stage" Underground Coal Gasification (UCG) technology has been put forward, and the UCG model platform has been built.
