Abstract:

The paper introduced the development situation and the newest progress of coal bed underground gasification in China and abroad， illustrated the advantages of underground coal gasification and the tough course of technology development. Underground coal gasification (UCG) is an important way to issue a series of technical and environmental problems in the traditional method of coal mining. The introduction was made on the improvement results of nonwell type underground coal gasification in ENN Group and the prospect of underground gasification coal mining was forecasted.
