| Outline of Final Research Achievements |
Developing a compact coaxial UCG system with a safe and high gasification rate, UCG model experiments were conducted using an artificial coal seam and a small-scale field experiment for untouched underground coal seams. A retrieval type horizontal coaxial UCG method was constructed to produce higher heat-value gas continuously. Its performance was assessed. Furthermore, a coal ignition method using a direct laser and a visualization system for combustion and gasification zone inside coal seams using AE (acoustic emission) measurements was established. For detoxification and decomposition of UCG production gas, results show that discharged plasma is effective for online processes. Moreover, for the field UCG experiment, an environment monitoring system was constructed for the air, surface, and underground, which confirmed that the UCG experiment did not influence the environment around the site. Consequently, a practical UCG system was developed in this study.
