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.
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.
