摘要
无底柱分段崩落法矿石残留体的形态和大小在端部放矿对放矿效果有着重大影响。通过宽甸硼矿的生产实践证明 ,留取适当的矿石残留体对降低贫化损失极为重要。
It has great influence on the effect of dilution drawing,that the shape and size of ore remained mass at the tope dilution drawing in sublevel caving mining without bottom pillars.Production practice in Kuan Dian mining has proved that reserveing proper remained mass is very important to decrease ore dilution and loss.
