Təhlükəsizlik qeydi
- This is a həndəsə yoxlayıcı, not a substitute for geotechnical stability analysis or rockfall analysis.
- It checks the consistency of pillə hündürlük, berm en, front angle, and overall slope angle, but it does not judge legal compliance.
- If the hədəf müqayisəsi is yaxın or on the təhlükə side, always have a geotechnical reviewer confirm the design.
- Water, blast damage, rock quality, equipment en, and drainage conditions are not part of this alət.
Necə istifadə etməli
- 1 Enter pillə hündürlük, berm en, front angle, and pillə count.
- 2 əlavə et a target overall slope angle if you want to compare the design against a reference angle.
- 3 Choose metrik or imperial, then aç ayarlar if you want to change precision or sharing behavior.
- 4 nəzərdən keçir the overall angle, the target marja, the exact-match values, and the previewed cross-section.
- 5 Use kopyala nəticə, kopyala paylaş URL, sıfırla, or the recent list to reuse the same condition later.
Nümunə
The same geometry in imperial
Giriş: Bench height 39.37 ft, berm width 26.25 ft, face angle 70°, bench count 4, target overall slope angle 52°
Çıxış: Overall slope angle 49.2°, margin +2.8°, safe side
Tez-tez verilən suallar
Is the angle measured from the horizontal?
Yes. Both the pillə front angle and the overall slope angle are measured from the horizontal.
What happens when berm en is 0?
The overall angle moves closer to the front angle, but the alət still warns you because that is rarely practical in the field.
What if the target angle cannot be matched exactly?
The required berm en or required front angle can fall outside a workable range. In that case the exact-match köməkçi shows that the target is not achievable with the current həndəsə.
Does this include lokal regulations or təhlükəsizlik standards?
yox. The alət stays limited to həndəsə and vahid conversion so that it can be used globally without embedding lokal rules.
Can I iş in both metrik and imperial vahidlər?
Yes. The vahid switch converts the pillə hündürlük and berm en while keeping the həndəsə and the formullar the same.
Lüğət
pillə hündürlük

Berm en
The horizontal en between benches.
front angle
The front angle measured from the horizontal.
Overall slope angle

Notes
- This alət does not cover water, partlatma, rock quality, or equipment clearance.
- If the hədəf müqayisəsi is yaxın the hədd, do not rely on rounding alone to make the decision.
- If your site has a regional standard or company standard, follow that first.
- Use this for geometric checks only. A real slope design still needs a geotechnical nəzərdən keçir.
