The objective of this study is to investigate the feasibility of a CMM recovery and utilization project at six mines owned and operated by JSC ArcelorMittal Temirtau Coal Division (AM). The gas resource data provided by AM are analyzed to determine the current and future projected gas resource from the six mines. Availability factors, which take into account fluctuations in gas flow and concentration, were calculated from historical data and applied to the projected resource data to calculate the realistic future gas resource.
