| Summary: | Underground Coal Gasification (UCG), an atypical technique for mining coal, could potentially unlock vast untapped coal reserves of Bangladesh. However, there was very little work done on UCG potentiality analysis considering the properties of all the coalfields collectively based on the worldwide experiences. To increase a better understanding from that perspective, this study was therefore of interest. The study explored the essential factors required to assess the
potentiality of UCG application for the five coalfields of the country. The threshold values were retrieved from published data of known trials occurred around the world. These were then compared with the available data of indigenous coalfields. In terms of the UCG prospects, all the coalfields passed the depth, thickness, ash content and rank factors
to a significant extent. But faulting, overburden or aquifer proximity are somewhat critical for all the coalfields except Jamalganj. In addition, Khalaspir field, despite having few discontinuities, would be a good candidate for UCG implementation once Jamalganj field reaches the
marker. This work might help initiating further steps through the analogous approach for siting the first UCG trial in the country. |
