煤层抽采及回风井排放的低浓度瓦斯大多不经处理直接排空或燃烧,针对这一现象所造成的瓦斯资源浪费、生态碳循环结构破坏和温室效应加剧等问题,分析了我国煤矿低浓度瓦斯的排污治理与资源利用技术,提出并验证了利用甲烷氧化菌来降解煤矿低浓度瓦斯的煤矿低浓度瓦斯治理技术,以期提高煤矿瓦斯的利用率,减少资源浪费和污染。
Most of the low concentration methane discharged from the coal seam and return well is emptied or burnt directly without treatment. According to the problems such as waste of gas resources, destruction of ecological carbon cycle structure and intensification of the greenhouse effect caused by this phenomenon, Concentration of methane emissions and resource utilization technology, proposed and verified by the use of methane oxidation bacteria to degrade coal mine low concentrations of low-concentration gas methane treatment technology in order to improve the utilization of coal gas and reduce waste of resources and pollution.
