Abstract：According to Panyi Mine east west rail up to support a 11-2 mining area ,based on the analy-sis of the influence factors of roadway deformation and destruction ,on the basis of combination of pre-stressed hollow grouting anchor cable with high intensity ,can realize the characteristics of deep grou-ting reinforcement ,the brush on the roadway are proposed of tents on the basis of using deep hole of hollow grouting anchor cable be in high strength anchor cable reinforcement.Engineering experiments show that the reinforcement scheme ,effectively control the deformation of roadway surrounding rock test achieved good supporting effect.
