煤层气开发过程中的排空与回收利用简述

With the improvement of the technology level, coalbed mathane is more and more widely used in life and production practice, for example, it can be used as civil fuel, industrial fuel, fuel and vehicle fuel, and it also can be used as an important chemical raw material,so it's application is extraordinary large. But in the exploitation and utilization of coalbed methane in the process, due to the limitation of the technological level of development、the existence of factors of potential risk、the lag of policy and other issues, not only waste cannot turned into treasure, but also serious coalmine accidents may occurre and cause the tragedy. This article attempts to do a simply summarize from the gas explosion and the recovery of coalbed methane on some obstacles and problems encountered in the development of coalbed mathane in the process, and try to lists some relevant suggestions and measures.
