摘要
徐楼铁矿采用长锚索维护顶板,采场底部结构布置在围岩中,矿岩分采、分爆、分开装运,从而降低了矿石的贫化和损失。
The long cable anchor is used to protect the stope roof in Xulou Iron Mine. The stope bottom is laid out in the surrounding rock, and the ore and rock are mining, blasting and transporting seperately, which reduces the ore dilution and loss.
