中深孔采场高品矿石单独回收采矿方法研究

Study on separate recovery and mining method of high grade ore in medium-deep hole stope

要随着生产的进行,越来越多的矿山采用中深孔崩落嗣后充填采矿法,因为其高效性、安全性使其应用普遍,但是其缺点是损失率、贫化率大,高品矿石无法单独回采,损失成本过大,所以如何在中深孔采场进行高品矿单独回收是摆在矿山面前的一难题。望儿山金矿根据自身的矿体情况,实施了中深孔采场高品矿单独回收的采矿方法,效果显著,顺利回收了高品矿,避免了高品矿损失。

As production proceeds,more and more mines adopt medium-deep hole caving and afterwards filling mining method.Because of its high efficiency and security,it is widely used,but its disadvantage is high loss rate and dilution rate,high grade ores cannot be recovered separately and the cost of loss is too high,so how to recover high grade ore separately recovery in medium-deep hole stope is a difficult problem.Wangershan gold mine according to its own conditions,the mining method of separate recovery of high grade ore in medium-deep hole stope has been implemented,the effect is remarkable,the high-grade ore is recovered smoothly and the loss of the high-grade ore is avoided.
