Modelling Underground Coal Gasification—A Review [PDF]
The technical feasibility of underground coal gasification (UCG) has been established through many field trials and laboratory-scale experiments over the past decades. However, the UCG is site specific and the commercialization of UCG is being hindered due to the lack of complete information for a specific site of operation. Since conducting UCG trials

Early Ideas in Underground Coal Gasification and Their Evolution [PDF]
This article follows the development of early UCG (underground coal gasification) ideas. Historical facts are discussed mainly from the technological perspective and early experiments in UCG are analyzed. Our search for the first successful UCG experiment brings to light a new finding, which was commonly overlooked in previous reviews.

Development of Underground Gasification of Coal in Japan
The possible application of underground gasification in Japan and some problems connected with it are now discussed by investigation committee of underground gasification. As well known this underground gasification techniques were mainly developed in Russia and now they produced gasified gas about 2500 million cubic meters per year.They gasify coal ...
