    Overall Slope Angle Vs Interramp Slope Angle

    The interramp slope angle is measured from toe to toe or crest to crest exclusive of any ramps Slope Stability in Surface Mining W.A. Hustrulid p48. By excluding ramps or other offsets the interramp angle is kept static no matter how many benches are measured. The interramp angle is similar to the face angle because it is static
