In order to improve the coal recovery rate of No. 2 coal seam in Tongxin Mine, according to the geological conditions of the 8201 working face, the pressure relief mechanism of the cutting roof was analyzed, and the numerical simulation method was used to displace the stress gauge of the surrounding rock at different cutting roof heights. The situation was studied, and the vertical height of the cut roof was determined to be 10.4 m. Based on the specific characteristics of the working face, the technical scheme of the cut-and-relieved pressure-retaining road along the goaf was designed, and the surface displacement of the roadway was observed. The results showed that after the implementation of the technology of cutting roof along the goaf, the maximum deformations of the top and bottom floors and the two sides during the stay were 620 and 116 mm, respectively, and the management of the top and bottom floors of the roadway needed to be strengthened during the mining.
