Abstract: The stability of roadway surrounding rock is the key to ensuring safe production in coal mines. Aiming at the problem of easy breakage and severe deformation of soft rock in the 2202 working face crossheading of Gaohe Coal Mine, combined with FLAC^3D numerical simulation and on-site testing, the length and row spacing parameters of anchor rods are systematically optimized, and a joint support design scheme for anchor net cables is proposed. The research results show that compared to the original support scheme (with an anchor rod length of 1.8 m, row spacing of 1000 mm × 800 mm), the optimized support scheme (with an anchor rod length of 2.4 m, row spacing of 500 mm × 800 mm) can reduce the roof displacement by about 19.35% and the depth of the plastic zone by about 37.25%. The on-site monitoring data indicates that under the optimized scheme, the roof subsidence is controlled between 92-103 mm, and the overall deformation of the roadway surrounding rock is effectively suppressed, and the support effect is significantly improved. This provides a quantitative basis and engineering reference for the optimization design of roadway support under similar geological conditions.
