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.
