| Abstract: | Special experiment equipment was developed and some M-T experiments were made in laboratory in order to find the relationship between bolt pretension torsional moments and its axial pre-stresses. FLAC3 D numerical model was established to simulate the pre-stresses distribution in surrounding rock and to find the relationship between bolt pre-stresses and roadway supporting effect. The analysis of monitoring results of experimental roadway showed the relationshio. |

| Keywords: | pre-stressed bolt pretension torisional moment axial pre-stresses supporting effect of roadway |
