Pit Wall Angles and Bench Width – How Do They Relate?

10/05/2015  The catch bench (“CB”) or berm is used to catch spalling rock and prevent it from rolling down the pit wall, creating a safety hazard. A rule of thumb is that the catch bench width should be according to the formula 4.5m + 0.2H, where H is the height of the bench. This means the recommended catch bench width for a 5m high bench should be about 5.5m; for a 10m high bench it should be 6.5m;

The impact of adapting Automated Haulage Systems to

Changes to road widths do not always translate to steeper overall pit wall angles and therefore a lower mine stripping ratio. AMC’s geotechnical engineers would review the pit design parameters considering both local and overall wall stability. Most open pit layouts will be improved with narrower ramps, but the impact must be properly considered over the entire pit geometry with a thorough ...
