Abstract: Aiming at the problems of large deformation and difficult support of the stoping roadway in the western rich water and weakly cemented soft rock mine affected by water-rock coupling action and under the influence of mining stress, taking the 3808S working face of Yushujing Coal Mine as the engineering background, the deformation and failure mechanism of the roadway with rich water and weakly cemented soft rock is revealed through on-site actual measurement, numerical simulation and theoretical analysis, and proactive advanced support collaborative control technology is proposed. The research shows that the deterioration effect of soft rock is significant when it comes into contact with water, and the roadway deformation is mainly exhibited as heaving floor, internal squeezing of the side, and roof layer separation, which traditional passive support is hard to effectively cope with; The proactive support system based on "high-strength anchor cable+steel belt+grouting reinforcement" can form a three-dimensional bearing structure, and achieve collaborative control through pre-tightening force diffusion and surrounding rock reinforcement. The on-site application results verify the feasibility of the technology, the improved technology reduces the displacement amount of the roadway roof and floor by 62%, reduces the displacement amount of the two sides by 58%, decreases the roadway repair frequency from an average of 12 times per year to 2 times, improves the excavation efficiency by 15%, and decreases the equipment failure rate from 8% per month to 2%, the roadway stability is significantly improved and solid technical support for mines under similar conditions is provided.
