Research Abstract

Underground Coal Gasification (UCG), a technology to convert more than 30 billion tons of unmined coal of Japan into energy resources, demands the establishment of a safe, high-performance and environmentally friendly UCG technology for application to Japan's coal seams, which have a complex geostructure. This study demonstrated the monitoring and control of fracturing activity around a combustion area in a coal seam and rocks using a series of laboratory experiments, small-scale field tests, and computer simulations.
