The mining process. The objective of pit slope optimisation programs during mining operations is twofold to develop safe operating conditions, and to minimise waste stripping ratios OBryan 2013. By achieving these two aims, the pit slope angle can be maximised, and in turn can have a significant impact to the economics of an open pit.

Therefore, the validity of the Modified Ritchie criterion for the design of catch bench widths in open pit mines with inclined benches must be questioned.

    Angle Of Repose Wikipedia

    2020-7-30The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0 to 90. The morphology of the material affects the angle of repose smooth, rounded.
