Open Pit Design - Inter-Ramp Angles and Volume Changes from Bench Geometry

Notes on Open Pit Design - Inter-Ramp Angles and Volume Changes from Bench Geometry

• This tool determines the inter-ramp angle for a specified bench geometry and the approximate change (%) in excavation volume due to a change in inter-ramp angle.
• All angles are specified in degrees.
• Bench dimensions are specified in metric or imperial units.

Tool developed and sponsored by Zostrich Geotechnical.
