In view of the big cross section coal roadway under high stress in XingDong Mine, the control problem of large deformation of surrounding rock of roadway, through field investigation, the big cross section coal roadway surrounding rock deformation mechanism were analyzed, the big cross section the stability control of coal roadway supporting strategy was discussed, finally the anchor cable pre-stress truss support scheme was proposed. Practice proved that the pre-stressed truss anchor cable support technology effectively solved the supporting problem of transportation roadway in 2223 working face of Xingdong Mine, saved construction cost, improved supporting effect and the stability of roadway surrounding rock, provided reference for other large-section coal roadway support at the same level.
