Abstract: The cutting roof pressure relief technology has been successfully applied in many mining areas,and has achieved huge social benefits.Dushanping Coal Mine of Xishan Coal and Electricity Group is a typical high gas mine.Great security risks.In view of this,the hydraulic fracturing technology was actively tested,the overall control idea of "lowlevel fracturing+highlevel weakening" was put forward,and the experiment was conducted with the 68310 return air lane as the engineering background.

Key words: high gas mine,pressure relief by roof cutting,roof strata,hydraulic fracturing
