TL;DR: In this paper, an unsteady state model for phase-II of underground coal gasification (UCG) is presented, where the growth occurs in the horizontal direction towards the production well through the outflow channel.

TL;DR: In this paper, the authors presented an unsteady-state model for gas production during phase-I for a coal under consideration for underground coal gasification (UCG), which can be used to determine feasibility of UCG for any other coal for the known kinetics and spalling parameters.

TL;DR: In this article, the authors studied spalling behavior of a lignite coal, which is characterized by high moisture and volatile matter, and suggested a possible underlying mechanism, and measured the rate of spalling using an experimental setup under the UCG-like conditions.

TL;DR: In this article, the authors present a systematic approach to be followed in laboratory to obtain data on both kinetics and diffusional effects for all the important reactions in underground coal gasification.

TL;DR: In this article, the effects of different operating conditions, coal properties and design parameters on key performance indicators (e.g., exit gas quality, energy generation rates etc) were examined. And the authors demonstrated the importance of a process model to determine the best conditions for UCG process and to evaluate feasibility of the process for a coal seam under consideration.
