摘　　要：随着伊敏露天矿产能提高至35.00 Mt/a,采掘设备再次进行大型化升级。为了未来能够有效减少剥离台阶数量,降低开采强度以及采场空间,进而减少年剥离量,伊敏露天矿对台阶高度进行了研究。通过在电铲可采高度范围内对不同台阶高度的对比分析,最终确定将台阶高度调整至14 m。With the production capacity of Yimin Open-pit Mine increased to 35.00 Mt/a,the mining equipment was upgraded again.In order to effectively reduce the number of stripping steps,reduce mining intensity and stope space in the future,and then reduce the annual stripping amount,Yimin Open-pit Mine conducted a study on the height of the steps.By comparing and analyzing the height of different steps within the range of mining height of electric shovel,the height of the steps is finally determined to be adjusted to 14 m.
