Abstract: In deep mines with kilometer-level shafts, the surrounding rock control is challenging due to the combined effects of “three-high conditions and dynamic disturbances”（high stress, high temperature, and high permeability pressure, coupled with mining-induced disturbances）. Among these issues, the deformation and failure of soft rock roadways under thick coal seam mining activities are particularly severe, threatening the safe extraction of working faces. Taking the 14th Mining Area of Kouzidong Coal Mine as the engineering background, this paper investigates the deformation and failure patterns of soft rock roadways during the final stage of mining at Face 140502. A mechanical analysis of roadway failure mechanisms is conducted, leading to the establishment of an energy-based failure criterion for surrounding rock. It is found that as the cantilever length L₃ increases, the energy U stored in the roadway’s surrounding rock also increases. The severe deformation and failure of roadways are attributed to the long-term high static stress acting on the surrounding rock, which becomes highly sensitive to dynamic disturbances, resulting in rapid fracturing and instability. Additionally, a mechanical model of the cantilever wedge-shaped structure at the working face is developed. The analysis reveals a negative correlation between the cantilever angle and the peak value of the advanced abutment stress, i.e., a larger cantilever angle corresponds to a lower peak stress. Based on these findings, a roadway control technology involving advanced blasting and roof cutting pressure relief at the stopping line is proposed. Theoretical analysis guides the design of key parameters such as drilling angles, heights, and positions for pressure relief. FLAC^3D simulations are utilized to optimize the roof cutting range, thereby reducing the required blasting workload. Finally, a blasting and roof cutting pressure relief scheme is implemented for Face 140504. Specifically, two identical blasting surfaces are positioned 17 m and 23 m outside the stopping line in the ventilation roadway of Face 140504. These blasts are initiated 150 m ahead of the mining face. Each section included five upward-inclined boreholes arranges in a fan-shaped pattern, carefully avoiding the existing high-level gas drainage roadway above the roof of Face 140504. During mining, monitoring of three major roadways shows that the sidewall convergence of the West Wing Return Airway, West Wing Main Conveyor Belt Roadway, and West Wing Track Roadway after Face 140504 extraction is 17.6 cm, 13.4 cm, and 8.4 cm, respectively. Compared to the convergence observed during Face 140502 mining, these values decrease by 64.08%, 60.59%, and 30%, demonstrating effective control and ensuring safe coal extraction.
