Abstract: Aiming at the problems of insufficient strength of the original support scheme and severe roadway deformation of the track roadway due to the high burial depth (442-659 m) and geostress in the 62707 working face of Du'erping Coal Mine, a non-coal pillar roof cutting and retaining roadway process is proposed. This process designs a type of differentiated anchor reinforcement scheme based on the roof asymmetric stress distribution, through along the direction of the roadway, three anchor cable belts are arranged in parallel near the side of cutting seams, in the middle of the roadway, and at the far end. According to the stress characteristics of each area, non-equidistant anchor cable row spacing of 1000 mm, 2000 mm, and 4000 mm are set respectively; The construction links are combined with the mechanical model of the cantilever beam to complete the support strength check computation. A 10.8 m borehole is adopted to configure constant resistance large deformation anchor cable and resin anchoring agent, and corresponding measures of bidirectional energy gathering pre-splitting and cutting blasting and zoning temporary support are implemented. The monitoring results show that this process effectively controls the height of the roof abscission layer within 20 mm, limits the upward curling amount of the floor to below 500 mm, and the monthly average deformation amount is less than 30 mm, the overall effect is better than the traditional coal pillar roadway protection process.
