营盘山采场中深部开采境界优化探讨

Deep mining boundary optimization of Yingpanshan stope of Lanjian Iron Ore Mine

攀钢兰尖铁矿是西南的特大型露天铁矿,经过30多年的生产,目前采场已进入深凹露天开采。文章结合生产实际,对营盘山采场中深部设计进行了优化探讨,提出了修改意见。通过对境界优化后,可使采场的开采更趋于合理,经济效益十分显著。

Lanjian Iron Ore Mine is the biggest open--pit mine in southwestern China. After more than 30 years of mining, the mine comes a stage of deep mining. After optimization of deep mining boundary, mining activities become reasonable thus achieving good economic benefit.
