A coupled thermal-mechanical numerical model of underground coal gasification (UCG) including spontaneous coal combustion and its effects [PDF]

open access: yesInternational Journal of Coal Geology, 2018
Underground coal gasification (UCG) is a promising option for extracting energy from coal in unworked or hard to access areas of the subsurface. From a geotechnical perspective, UCG involves various complex phenomena resulting from the elevated temperatures induced within the rock surrounding the UCG burn.

Ranking of coal seams for underground coal gasification (UCG) in Mazino coal deposit, Tabas coal field, Iran

open access: yesJournal of Geology and Mining Research, 2014
The underground coal gasification (UCG) has a potential for converting the world’s coal resources into energy, liquid fuels and chemicals. The UCG process involves the injection of steam and air or oxygen into an underground coal seam and igniting and burning of coal in-situ to produce the combustible gas.
