Overall Slope Angle Vs Interramp Slope Angle
2020-4-29Overall Slope Angle vs. Interramp Slope Angle In the mining industry nomenclature can be very important. This became especially clear to me a few weeks ago when discussing the slope angle of an open pit mine.
Considerations In The Optimisation Of Bench Face
2020-4-22The bench face angle and berm width geometries must be chosen to fit the bench stack angle but must provide a berm that will be capable of catching the volume of failed wedge material from the bench faces above. Other considerations for bench height and berm width are equipment sie ore selectivity and blasting design.
Considerations In The Optimisation Of Bench Face
2020-3-19The inclination of any pit wall composed of stacks of benches is limited by the overall quality and structural complexity of the rock mass in which the slope is situated. For a bench stack angle that satisfies the stability criteria various combinations of bench height bench face angle and berm width can be used in the slope design.

Geotechnical Optimisation Of The Venetia Open Pit
2013-2-18GEOTECHNICAL OPTIMISATION OF THE VENETIA OPEN PIT ABSTRACT Venetia Mine is situated south of the confluence of the Shashi and Limpopo rivers 80 km West of Musina and 36 km North-east of Alldays in South Africa. Venetia is an open pit truck and shovel operation which commenced full production in 1993. Mining began on the
Influence Of Bench Geometries On Rockfall
2013-7-22Modified Ritchie criterion only for the 90o bench face angle in all rock types those with 60o 70o and 80o bench face angle provide a larger maximum run-out distance. 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.
