Energies Free Full-Text The Underground Coal Gasification
The underground coal gasification (UCG) process represents a modern and effective coal mining technology that enables coal energy extraction through thermic decomposition. The coal is transformed into syngas by oxidizers (e.g., air, technical oxygen, or water steam) and is injected into a georeactor. The produced syngas is exhausted on Underground coal gasification (UCG) is a promising option for the future use of un-worked coal. UCG permits coal to be gasified in situ within the coal seam, via a matrix of wells.The coal is ignited and air is injected underground to sustain a fire, which is essentially used to “mine” the coal and produce a combustible synthetic gas which can Underground coal gasification: From fundamentals to

Advanced geophysical underground coal gasification monitoring
Underground Coal Gasification (UCG) produces less surface impact, atmospheric pollutants and greenhouse gas than traditional surface mining and combustion. Therefore, it may be useful in mitigating global change caused by anthropogenic activities. Careful monitoring of the UCG process is essential in minimizing environmental impact. Underground Coal Gasification. The economic depth of coal mining is perhaps around 3000–4000 ft. This mineable reserve is merely 1 T ton leaving a vast reserve (14–29 T tons) unexploited. In the author's opinion, the gas contained in these reserves should be first recovered by hydraulic fracturing of horizontal laterals [4].CO2 sequestration and underground coal gasification with
