| 摘 要： | 凤凰山铜矿已对-240m中段以上的残矿进行回采，以稳定矿山的生产能力。上部残矿的回采必将影响到深部中段开采的稳定性。通过力学模型对-240m中段的水平矿柱稳定性进行计算、分析，初步得出了结论，并对矿床深部的安全回采提出了3点措施。

| Abstract: | Fenghuanshan Copper Mine is extracting the residual ore above the -240 m level of middle section so as to stabilize the production capacity of the mine,which will inevitably affect the stability of the deep mining of the middle section.Calculation and analysis are made of the stability of the horizontal ore pillars of -240 m level of the middle section using a mechanical model.Preliminary conclusions are drawn and three measures for the safe mining of the deposit at depth proposed. |

| Keywords: | Horizontal ore pillar Mechanical mode Stability Safe span between ore pillars |
