| 摘 要： | 无底柱分段崩落法低贫化放矿方式要求限制废石漏斗在出矿口的破裂。白银深部铜矿矿岩界限很不明显且围岩含有品位 ,在出矿口根据肉眼判断废石漏斗的破裂误差大 ,且出矿管理难度大 ,为此 ,采用控制放出矿量的方法 ,较好地实现了低贫化放矿问题。

| Abstract: | The low dilution mode of ore drawing requies that ore quality management be suited to the feature of ore and rock movement during ore drawing in sublevel caving.The paper adopts a new way of limiting ore drawing quantities to control ore dilution due to the difficulty in recognizing rock and ore as well as the fact of existing ore bearing rock in Baiyin Copper Mine. |
