what is a stack angle in open pit mining Mining Openpit mining Wikipedia the free encyclopedia Openpit mines are typically enlarged until either the mineral resource is exhausted Most walls of the pit are generally dug on an angle less than vertical »More detailedget priceFurther Details
The 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 The bench face angle and berm width geometries must be chosen to fitFurther Details
