Model-Free Control of UCG Based on Continual Optimization of Operating Variables: An Experimental Study

Energies, 2021
The underground coal gasification (UCG) represents an effective coal mining technology, where coal is transformed into syngas underground. Extracted syngas is cleaned and processed for energy production.

Computational Studies for Underground Coal Gasification (UCG) Process

IOP Conference Series: Earth and Environmental Science, 2017
Underground coal gasification (UCG) is a well proven technology in order to access the coal lying either too deep underground, or is otherwise too costly to be extracted using the conventional mining methods. UCG product gas is commonly used as a chemical feedstock or as fuel for power generation.

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

Journal 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.
