中国煤炭生产甲烷排放现状及对策研究

Emission Situation of Methane Caused by Coal in China and Some Countermeasures

指出了煤炭行业的甲烷排放也是造成温室效应的重要因素之一,气候的变化直接影响到人类社会的可持续发展,我国有着丰富的煤层气储藏量,为发展新清洁能源奠定了坚实的基础,但是由于政策和技术限制,我国煤炭行业每年向大气中排放了大量的煤炭甲烷气体,尤其是低浓度煤炭甲烷,造成了资源浪费的同时也是煤炭生产安全的隐患。结合我国煤炭甲烷排放特征,分析了我国煤炭甲烷排放现状和主要的利用技术,并提出了中国煤炭甲烷排控的对策。

The emission of methane in coal industry is also one of the factors that lead to the greenhouse ettect, tne change in climate directly affects the sustainable development of human society. China has rich coal bed methane reserves, which establishes solid foundation for developing new clean energy. However, due to the limit of policy and technology, Chings coal industry annually has let out a mass of coal methane to atmospheric air, especially the low concentration coal methane. This not only causes resources waste but also leaves hidden danger in the production of coal. Combining with the characteristics of coal methane emissions, this article analyzes the current situation of emission and the utilization of the main technology. In addition, the article proposes the controlling strategy for coal methane emission.
