Historical data on mining and methane emissions, as well as the long-term methane production data monitored at the Hangard shaft was used to validate the model developed. A satisfactory match tothe historical and currrent field data was achieved. Predictionsfor future production opportunities were made for the Allenfeld shaft in conjunction with production from the Hangard shaft which has been in production since 1960.enmetallurgical and materials engineeringArticle
