Geomechanical Modeling of Underground Coal Gasification

open access: yes, 2016
The geomechanical responses of a coal seam and its surrounding strata in underground coal gasification (UCG) are significant owing to the high temperature nature of the UCG process and the cavity evolution. In this thesis, the results from a reservoir simulator are coupled with a geomechanical module to solve for the displacement and stress variations.

The analysis of the underground coal gasification in experimental equipment

open access: yesEnergy, 2016
AbstractThis paper describes an experiment of underground coal gasification in experimental equipment. The experiment was done within the range of the project APVV-0582-06, in May 2010. During the period of 63 h there was gasified amount of 214 kg of coal in experimental gasifier with average rate of 3.4 kg/h.
