摘要： 为了找出更高效的煤矿超低浓度瓦斯气发电方式，计算了不同甲烷浓度下煤矿乏风采用蒸汽、燃机等不同发电方式时的效率。计算结果表明，多级压缩中间冷却带回热的燃气轮机发电效率最高，在甲烷质量浓度超过1%时，其最高效率甚至超过了50%。采用燃机发电还具有系统结构简单以及不消耗水资源的特点。

Abstract: In order to find more efficient power generation of ultra-low methane gas concentrations of coal mine, the efficiency of different concentrations of coal mine ventilation air methane in different power generation ways of steam generation, gas turbine power generation were calculated，the results show that the efficiency of multi-stage compression with intermediate cooling of the gas turbine power generation with the regenerator is highest, when the methane concentration exceeds 1%, the highest efficiency even more than 50%. Using a gas turbine power generation system, also have good features of simple structure and does not consume water.
