| Abstract: | To solve the hidden safe trouble of No.5 ore conveyor belt upper slope of Qidashan Iron Mine, the geological investigation and stability analysis of lithologic composition and rock mass structure has been carried on. The failure mode of whole slope is circular shear failure, and failure mode of bench slope is double sliding surface shear failure and vertical rock dumping collapse. The factor of safety of shear failure mode is greater than 2.0 for whole slope and bench slope. The Rolling Stones under the action of weathering and vibration is the main harmful consequences. The final slope control plans will be comprehensive reinforcement measures with 12m whole-length cohesive anchor bolt and SNS actively flexible defend net. |
