Coal Seam Roof and Floor Lithology Prediction for Underground Coal Gasification Based on Deep Residual Shrinkage Network

Energy Science &Engineering, Volume 13, Issue 3, Page 1361-1374, March 2025.
This study proposes the deep residual shrinkage network (DRSN), a model combining advanced strategies for rapid and accurate lithology prediction. It enables efficient lithology evaluation in early underground coal gasification. ABSTRACT Lithology identification is a crucial task in coal underground gasification projects, serving as a prerequisite for ...

Water leaching of inorganic species from coal ash and slag generated at typical Underground Coal Gasification (UCG) temperatures

, 2017
MSc (Chemistry), North-West University, Potchefstroom Campus, 2017 Underground coal gasification (UCG) is a better and more environmentally friendly way of gasifiying coal, using coal seams that are not economically viable to mine or coal seams that are deep underground. This technology has a lot of advantages in comparison with conventional or surface
