To find the slope percentage, divide the vertical height (VH) by the horizontal distance (HD), and multiply the result by 100.
The Bench Slope Calculator is a very useful tool. This tool is used in mining and civil engineering projects. It helps find out the slope angle or percentage of a bench.
Whereas, in mining, the term bench refers to a step or level created during excavation, which needs a precise slope to ensure safety and stability. Accurate bench slope calculations can help prevent collapses and aid in planning.

What is Bench Slope Calculator?
A Bench Slope Calculator is a fine tool that is used to measure the slope or inclination of benches, commonly in mining, civil engineering, and construction projects. In mining, benches are horizontal intervals in an open-pit mine or quarry that allow for safe extraction of materials.
Key Concepts:
- Bench Slope Angle: The angle between the horizontal bench and the inclined surface of the bench face.
- Inter-Ramp Angle: The angle between the horizontal and the line connecting the crests of two consecutive benches.
- Overall Pit Slope Angle: The average angle of the entire pit, including all benches.
Applications:
- Mining: To calculate the bench slope angle and ensure stable excavation.
- Road construction: To ensure safe and navigable slopes.
- Drainage design: To provide proper water runoff.
Other related calculators:
- Overall pit slope angle formula: To calculate the average slope for a mining pit.
- Inter-ramp angle calculator: To determine the slope angle between multiple benches for safe mining.
- Rock value and grade calculators: Useful in assessing the economic feasibility of mining a particular area.
Final Words:
In total, for more precise calculations, you can use specialized bench slope calculator PDFs or online tools that provide additional features, such as calculating inter-ramp angles based on bench heights and safety considerations.
