Underground coal gasification
D. W. Gregg,Thomas F. Edgar +1 more
TL;DR: Underground coal gasification (UCG) is a method whereby the mining and conversion of coal are accomplished in a single step as mentioned in this paper, and many field tests of UCG have been operated worldwide since the 1930's with varying degrees of success; a field design which is applicable to a wide range of geological conditions and coal properties has evolved.

Public perceptions of underground coal gasification in the United Kingdom
TL;DR: In this article, the authors explored the public perceptions of underground coal gasification (UCG) in the UK through a detailed case-study and focus group discussion, and recommended that an open, transparent and consultative process of decision-making and operation should be adopted by the developer, operator and regulator.
Journal ArticleDOI
Reactor Model for the Underground Coal Gasification (UCG) Channel
TL;DR: In this article, the gasification channel is viewed as a one-dimensional packed bed reactor and a pseudo-transient model is simulated for temperature and composition profiles of the gas and solid phases.
