Deschide Pit Banchet Design Verificăer
Calculează the overall pantă angle from banchet înălțime, berm lățime, face angle, and banchet count.
Compară the rezultat with a țintă angle, see the safe / near / danger status, and preview the section in the browser.
Siguranță notificare
- This is a geometry verificator, not a substitute for geotechnical stability analysis or rockfall analysis.
- It checks the consistency of banchet înălțime, berm lățime, face angle, and overall pantă angle, but it does not judge legal compliance.
- If the țintă comparison is near or on the danger side, always have a geotechnical reviewer confirm the design.
- Apă, blast damage, rock calitate, equipment lățime, and drainage conditions are not part of this instrument.
How to use
- 1 Enter banchet înălțime, berm lățime, face angle, and banchet count.
- 2 Add a țintă overall pantă angle if you want to compară the design against a reference angle.
- 3 Choose metric or imperial, then deschide Setări if you want to change precision or sharing behavior.
- 4 Review the overall angle, the țintă margin, the exact-match values, and the previewed cross-section.
- 5 Folosește Copiază rezultatul, Copiază URL-ul de partajare, Resetează, or the recent list to reuse the same condition later.

Întrebări frecvente
Is the angle measured from the horizontal?
Da. Both the banchet face angle and the overall pantă angle are measured from the horizontal.
What happens when berm lățime is 0?
The overall angle moves closer to the face angle, but the instrument still warns you because that is rarely practical in the field.
What if the țintă angle cannot be matched exactly?
The required berm lățime or required face angle can fall outside a workable range. In that case the exact-match helper shows that the țintă is not achievable with the curent geometry.
Does this include local regulations or siguranță standards?
Nu. The instrument stays limited to geometry and unitate conversion so that it can be used globally without embedding local rules.
Can I work in both metric and imperial unități?
Da. The unitate switch converts the banchet înălțime and berm lățime while keeping the geometry and the formulas the same.
Glossary
Banchet înălțime
The vertical înălțime of one banchet.
Berm lățime
The horizontal lățime between benches.
Face angle
The face angle measured from the horizontal.
Overall pantă angle
The angle of the whole banchet stack when you look at the section from crest to toe.
Face setback
The horizontal run of one banchet face.

Nutes
- This instrument does not cover apă, blasting, rock calitate, or equipment clearance.
- If the țintă comparison is near the threshold, do not rely on rounding alone to make the decision.
- If your site has a regional standard or company standard, follow that first.
- Folosește this for geometric checks only. A real pantă design still needs a geotechnical review.
