| Abstract: | There is an essential difference in failure mechanism between extra-deep excavation in rock and soil one.Based on the numerical simulation of the real extra-deep excavation,the relations of the fracture types and the fracture mechanism with depth of the excavation are studied.The working principles and the reinforcement effect by means of pre-tensioned bolts are analyzed. |

| Keywords: | extra-deep rock excavation fracture types fracture mechanism slip field pre-tensioned bolts |
