Coal mine methane is a general description for all methane released prior to; during and after mining operations. As such; there is considerable variability in flow rate and composition of the various gas emissions during mining operations. It would be highly desirable to recover energy from emitted methane of coal mine to generate electricity. Hence; more attention should be focused on the effective utilization of emitted methane in coal mines. The energy recovery system; as one of the promising technologies; has been attracting increased attention to generate electricity from emitted methane in Tabas mine. Some energy recovery systems with different configurations may be proposed such as gas turbine and gas engines. In this investigation; a simulation model has been developed in Hysys software environment to predict generated power from combination of ventilation air and drainage gas (mixture with 1.6 % methane concentration) form Tabas mine by using a leanburn gas turbine.
