| Abstract: | Arched top pillars are introduced based on the results of finite elementary numerical analysis. Screw-shaped long cable-based consolidation technology is adopted for the layered rockmass in the hanging wall so that the mining operation in the open stope in a highly stressed area can proceed smoothly in Baiying Deep Copper Mine. |

| Keywords: | Open stope mining Arched top pillar Long cable support |
