摘要
介绍了通钢集团板石矿业公司上青矿针对露天边坡压盘矿,采用高分段放矿,节省了矿石二次倒运费用,提高了采矿强度、出矿品位及铲运机的工作效率。通过一年多的生产实践,取得了较好的技术指标和经济效益。
To recover residual ore at slope of Shangqing Iron Ore Mine, the method of high--sublevel ore withdrawal is adopted that has advantages such as saving of ore's secondary hauling, increase of mining intensity and rise of grade of ore withdrawn. The over one--year practice using this method shows good economical benefit.
