Abstract: The ore and rock mass of Jinshandian Iron Mine is very cracked，the metal bolts supported failure is serious because of corrosion，So the problem of development working failure is serious. Because of the good characteristics of glass fiber reinforced polymer (GFRP) anchor，the paper study of using GFRP bolt supporting to replace screw-thread steel bolt supporting. The paper analyzed the supporting effect of screw thread steel anchor and GFRP anchor under the mining condition based on numerical analysis. The numerical analysis show that using GFRP anchor supporting can effectively change the neutral point position，and can improve the stress distribution characteristics of cable grout，thereby the bolt capacity of resistance to tunnel deformation is improved. Based on the GFRP bolt supporting industrial test and monitoring，the paper analysis the testing tunnels convergence deformation and discusses the GFRP bolt supporting problems in Jinshandian Iron Mine. Experiments show that using GFRP bolt or screw thread steel anchor supporting can achieve the same effect in controlling the deformation of tunnel，but the tail of GFRP bolt destroyed easily under blasting shock effect，and the nut easily shedding under the large tunnel deformation effect. So the GFRP bolt can not continue to provide effective extrusion pressure and the metal net fall off until the entire bolt failure.
