矿井排风是重要的瓦斯排放源，实现矿井风排瓦斯减排利用，对促进我国节能减排具有重要的作用．分析了我国矿井风排瓦斯现状，评述了现有的矿井排风瓦斯减排利用方法，提出了矿井风排瓦斯节能减排计算方法，并分析了我国矿井风排瓦斯减排利用潜力．分析结果表明，我国目前每年通过矿井排风排放的瓦斯量在200×108～250×108 m3，通过对这部分瓦斯减排利用，可实现年节约1200×104～1700×104 t标准煤，减少温室气体排放当量3×108～4×108 t，实现全国年减排3．5％．

Mine ventilation is one of the major emission sources of methane,and thus it has an important role in energy saving and greenhouse gas (GHG)emission reduction in China via mitigation and utilization of ventilation air methane (VAM).This paper gives an analysis of the current status of VAM in China.The mitigation and utilization technologies of VAM are reviewed.A calculations method for energy saving and GHG emission reduction of VAMis proposed,and the energy saving and GHG emission reduction potentials of VAMis analyzed.Results show that the current emission amount of VAM in China is about 200 ×108 ~250 ×108 m3 every year.An energy saving of 1 .2 ×107 ~1 .7 ×107 t ce and a GHG emission reduction of 3 ×108 ~4 ×108 t CO2eq,which accounts for about 3.5%of the total GHG emission of China.Can be achieved every year,if the VAM can be mitigated and utilized in China.
