The intersection point of Xinyuan Mining Industry east auxiliary roadway No. 2 contact roadway and returning airway was the point of new roadway and original roadway cutthrough， new roadway disturbance influence broke the original roadway surrounding rock stress state of equilibrium， which led surrounding rock loose circle become bigger in roadway intersection point， with roadway deformation， all anchor cable (7.3 m cable) + dense column for support， with 9 12 m anchor cable new support scheme was put forward， through the observation of intersection surface displacement and roof separation seam after construction， the support technology met the needs of intersection point support strength， which could control roadway deformation effectively and get good support effect， ensure the safe needs of mine ventilation and people.
