| Abstract: | In this paper,aiming at the surrounding rock control problem of mining roadway in Xiegou Coal Mine,hydraulic fracturing roof cutting and pressure relief technology is used to weaken the roof of 18104 material roadway in mining face.Through drilling peep inspection,it is concluded that there is a significant vertical fracture zone in the borehole,which can realize the timely cutting off of the basic roof in mining face,so as to ensure the stability of surrounding rock of mining roadway. |
