Abstract
In a recently completed EC- Thermie research project, jointly carried out by Imperial College and DeutscheSteinkohle Aktiengesellschaft (DSK), an in house gas-water two-phase CBM simulator developed at ImperialCollege London was modifi ed to simulate abandoned mine methane recovery in the Saar Coalfi eld. Historical data onmining and methane emissions, as well as the long-term methane production data monitored from the Hangard shaftwas used to validate the model developed. A satisfactory match to the historical and current fi eld data was achieved,and predictions for future production opportunities were made.
