Coalbed methane (CBM) occurring in almost all coal beds can be released through fracturing, which will not only provide a clean energy resources but enhance production safety in coal mining. The features of CBM determine adoption of experiment method and the particularity of final conclusion. This paper focuses on experimental evaluation of long-term conductivity of fracturing in coal beds. The results show that different from sandstone strata, coal beds are of low hardness and easily broken, and embedment of various fragments in fractures is very common.
