Abstract: Taking the roadway layout and surrounding rock control of 15106 return airway in gob-side entry driving in Wenzhuang Coal Industry as the engineering background, by means of field measurement, theoretical analysis and other means, Trigon numerical model was established according to UDEC polygon failure criterion, the distribution range of lateral supporting stress in goaf adjacent to 15106 return airway was analyzed, and the internal stress of coal pillar with different widths, the characteristics of crack expansion and the deformation law of surrounding rock of roadway were further analyzed. The reasonable narrow coal pillar width of 15106 return airway was determined to be 5 m based on the length of crack closed area. The supporting technology of high strength rockbolt and anchor cable with reinforced ladder beam was put forward. Mine pressure observation results show that when the width of coal pillar is 5 m, the deformation of roadway surrounding rock is small, and the high strength rockbolt and anchor cable can stably bear the load, at the same time, there is a certain length of crack closed zone in the middle of the coal pillar, which verifies the rationality of the 5 m coal pillar width and surrounding rock control technology.
