In order to solve the roadway deformation problem of gob-side entry driving in Xipang Mine of Dongpang Mine, No. 9119 Face was taken as the research object, the technical scheme of hydraulic fracturing roof cutting and roadway protection was formulated, and the roof hydraulic fracturing roadway was constructed for 240 m. The application results showed that after the roof hydraulic fracturing pressure relief construction, the roadway in the influence range of dynamic pressure was reduced by about 500 mm on average, and the cost was saved by 172,900 yuan, and the deformation problem of gob-side entry retaining narrow coal pillar was effectively controlled.
