摘　　要：为高效利用超低浓度瓦斯氧化热能和低温热能,针对抽采瓦斯浓度低、利用率低和传统锅炉热能不足以满足煤矿需求的问题,在充分分析矿井瓦斯气源和利用模式的基础上,丁集煤矿建立了超低浓度瓦斯蓄热氧化及低温热能利用示范工程。实践结果表明,该技术可使低浓度瓦斯利用率达到98%以上,基本实现瓦斯零排放;年节约标煤1.3万t,直接经济效益700余万元,满足煤矿2.3×10^11 kJ/a的用热需求,每年还减少CO 2排放量约30万t,经济效益和环保效益显著。In order to make full use of ultra-low concentration gas oxidation heat energy and low temperature heat energy,aiming at the problems of low concentration of gas extraction,low utilization rate of heat energy and the traditional boiler heat energy cannot meet the needs of coal mine,on the basis of fully analyzing the gas source and utilization mode of coal mine,the demonstration project of ultra-low concentration gas oxidation and low temperature heat energy utilization is established in Dingji coal mine.The practice results show that the technology can make the utilization rate of low concentration gas reach more than 98%,basically achieve zero gas emission,save about 13000 tons of standard coal annually,generate more than 7 million Yuan of direct economic benefits,meet the heat demand of 2.3×1011 kJ/a in coal mine,and reduce about 300000 tons of carbon dioxide emissions annually,with remarkable economic and environmental benefits.
