摘要
西部铜业公司近年来成功使用了分段空场法和浅孔留矿法。随着采矿深度、强度的不断加大,继续采用原来的采矿方法存在损失贫化大、安全性差等技术问题。通过采用灰砂和废石充填采空区的充填采矿法,合理开采利用矿产资源,降低了损失、贫化,从而提高了经济效益。
The sublevel open slope method and short hole shrinkage method have been successfully used in Western Copper Corporation in recent years.With the increasing of mining depth and intensity,the original mining methods would lead to high loss rate and dilution rate,poor security and so on.The mineral resource was reasonably utilized,and the losses and dilution were reduced by using cut-and-fill method,and which increased the economic benefits.
