Based on the layout of staggered roadway in 907 auxiliary transportation roadway of Qipanjing Mine, the technical analysis of combined support for staggered roadways was carried out, it was concluded that the influence of stress redistribution disturbance on surrounding rock of staggered roadway was complex, the closer the distance between staggered roadways, the more serious the disturbance of stress in surrounding rock between roadways, even the crack failure of surrounding rock mass between roadways extended to the middle of roadways and led to crack penetration, which caused bearing instability of surrounding rock of staggered roadway. Therefore, aiming at this engineering problem, the technical scheme of “bolt + anchor + steel shed” combined support technology scheme was proposed for the staggered position of roadway, and through the field deformation monitoring results, the deformation of surrounding rock in 907 auxiliary transport roadway was generally 15 ~ 64 mm, the current support scheme realized the surrounding rock control of 907 auxiliary transport combined roadway near staggered roadway.
