Abstract. Underground coal gasification is a conversion and extraction process, for the production of useful synthetic product gas from an in-situ coal seam, to use in power generation, heat production or as a chemical feedstock. While many variants of the underground coal gasification process have been considered and over 75 trials …

Our assumption was gasification of one million tons of coal within a period of 10 years. The production cost of gases per heating value was estimated to be between US$0.029/MJ and US$0.045/MJ. Finally, the authors proposed a boring cost saving UCG method, STRIP ( ST ream Method with R etracting I njection P oint) method, for its further ...

Underground Coal Gasification (UCG) is one of the methods of recovering energy from underground coal seams. In 1970's and 1980's, many basic studies and field tests on UCG were carried out in the USA. Although the activity on UCG has been interrupted, because of the recent low oil price in the world energy market, the …
