Abstract：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.
