Abstract： In this paper, the problems of floor heave, slurry peel off, I-beam bending, anchor cable breakage and obvious mine pressure in the 750 ~ 950 m section of Lunan No.15 coal auxiliary transportation roadway of Xinjing Company are analyzed, and it is pointed out that the 15317 working face will disturb the dynamic pressure of Lunan No.15 coal auxiliary transportation roadway. Therefore, it is decided to apply hydraulic fracturing pressure relief technology to the 750 ~ 950 m section of Lunan No.15 coal auxiliary transportation roadway, and the corresponding hydraulic fracturing pressure relief scheme is put forward. The practice shows that after the implementation of the pressure relief scheme, the deformation of the roadway is small, the secondary roadway is no longer needed, and the pressure relief effect is good.
