摘　　要：煤矿瓦斯综合利用是煤炭企业实现碳达峰、碳中和目标的重要手段。针对超低浓度瓦斯大量排放和资源化利用的技术短板,结合小庄煤矿瓦斯抽采及利用现状,提出了“蓄热氧化技术”。在分析超低浓度瓦斯蓄热氧化技术原理的基础上,制定相应的供热及发电方案,分析了超低浓度(10%以下)煤矿瓦斯利用的运行情况及应用效果。实践表明,该技术方案经规划实施后经济效益和环保效益显著,为抽采浓度低于8%的矿井提供了瓦斯利用的方法与借鉴。The comprehensive utilization of coal mine gas is an important means for coal enterprises to achieve the goal of carbon peak and carbon neutrality.Aiming at the shortcomings in the application of large volume discharge and resource utilization technology for ultra-low-concentration gas,combined with the current situation of gas extraction and utilization in Xiaozhuang Coal Mine,we put forward the“thermal storage and oxidation technology”,formulated a series of implementation plans,and analyzed the effectiveness of the utilization of ultra-low-concentration(less than 10%)coal mine gas.The practice shows that the remarkable economic and environmental benefits have been achieved after implementation of this technical scheme,providing reference for the utilization of low concentration(8%)of extracted gas.
