煤层气（CBM）是一种新型的清洁能源，我国CBM资源十分丰富，但多半直接排放到大气中，资源浪费大，对大气污染严重。介绍了CBM的成因、使用技术，并着重分析了低甲烷含量煤层气及含氧煤层气（OCCBM）的处理技术，并对其可能的发展前景进行了综述，提出通过脱氧技术实现纯化再进行应用将是其未来的发展方向。

Coalbed methane (CBM) is a kind of clean energy.China's CBM resource is very rich,but most of them have been discharged into air,wasting resources and polluting atmosphere.This paper introduces the formation mechanism and utilizing techniques of CBM,and analyzes emphatically the tackling technology for the CBM with low methane content and oxygen-containing CBM (OCCBM).The potential development outlook for comprehensive utilization of CBM and OCCBM in the future is prospected,and purification through deoxidation techniques before application and utilization is recognized as the future direction of development.
