| Abstract: |
| In the nonferrous metal mine which using underhand drift stoping and tailings cemented filling, the stability, safety and convenience of retaining wall have a direct influence on the safety and efficiency of the production. According to the empirical method and engineering analogy method, Yiliang Chihong mining company has determined the parameters of access retaining wall. Finally, they optimize the parameters and production requirements of retaining wall, ensure the quality of retaining wall and the security of production, simplify the production process, shorten the time of production, maintenance and adjacent access stoping, and increase work efficiency by researching and analyzing the retaining wall’s static pressure forced by paste, the shear?bond?resistance between retaining wall cement and ore-rock, the shear resistance of bolt, etc. |
