Monitoring the gasification area and its behavior in underground coal gasification by acoustic emission technique instead of temperature measurement. [PDF]
Sci Rep, 2023 Underground Coal Gasification (UCG) requires monitoring of the gasification area because the gasification process is invisible and the reaction temperature exceeds 1000 °C.

Current status and technology development in implementing low carbon emission energy on underground coal gasification (UCG) [PDF]
Frontiers in Energy Research, 2023 Although coal mining has played a substantial role in world’s development as a critical fuel source for at least 25 years, its value is partly offset by the massive environmental issues it presents during combustion.

Insights into bacterial diversity in industrial post-processing water from underground coal gasification (UCG) process [PDF]
Archives of Environmental ProtectionThis study represents the first culture-independent profiling of microbial diversity in post-processing wastewater from underground coal gasification (UCG) processes. Three types of post-processing wastewater, named W1, W2 and W3, were obtained from three UCG processes involving two types of coal and two gasification agents, namely oxygen-enriched air ...

Assessment of underground coal gasification in bituminous coals: potential UCG products and markets. Final report, Phase I [PDF]
, 1982 The following conclusions were drawn from the study: (1) The US will continue to require new sources of energy fuels and substitutes for petrochemical feedstocks into the foreseeable future. Most of this requirement will be met using coal. However, the cost of mining, transporting, cleaning, and preparing coal, disposing of ash or slag and scrubbing ...
