Abstract：In order to find a more efficient method for power generation with ultra-low-concentration methane of coal mine,the efficiency of different power generation methods,including steam generation,gas turbine power generation are calculated,with different concentrations of coal mine ventilation air methane.The results show that the efficiency of recuperative gas turbine power generation with multi-stage compression and intermediate cooling is the highest.When the methane concentration exceeds 1%,the maximum efficiency is more than 50%.The gas turbine power generation system is of simple structure and consumes no water.
