Design of open pit mining

Many factors govern the size and shape of an open pit.

These must be properly understood and used in the planning of any open pit operation.

The following are the key items affecting the pit design:

1) Topography,

2) Geology,

3) Grade,

4) Localization of the mineralization,

5) Extent of the deposit,

6) Property boundaries,

7) Production rates,

8) Road grades,

9) Mining costs,

10) Processing costs,

11) Metal recovery,

12) Marketing considerations,

13) Bench height,

14) Pit slopes,

15) Cutoff grade,

16) Strip Ratios (SR)
