Heometriya ng open-pit

Open Pit Bench Design Checker

Kalkulahin ang overall slope angle mula sa bench height, berm width, face angle, at bench count.

Ihambing ang resulta sa target angle, tingnan ang status na safe / near / danger, at silipin ang section sa browser.

Paano gamitin

Paunawa sa kaligtasan

  • Geometry checker ito, hindi kapalit ng geotechnical stability analysis o rockfall analysis.
  • Sinusuri nito ang consistency ng bench height, berm width, face angle, at overall slope angle, pero hindi nito hinuhusgahan ang legal compliance.
  • Kung malapit o nasa danger side ang target comparison, ipasuri muna sa geotechnical reviewer ang design.
  • Ang tubig, pinsalang dulot ng blast, kalidad ng bato, lapad ng equipment, at kondisyon ng drainage ay hindi saklaw ng tool na ito.

Paano gamitin

  1. 1 Ilagay ang bench height, berm width, face angle, at bench count.
  2. 2 Magdagdag ng target overall slope angle kung gusto mong ihambing ang design sa isang reference angle.
  3. 3 Piliin ang metric o imperial, pagkatapos buksan ang Settings kung gusto mong baguhin ang precision o sharing behavior.
  4. 4 Suriin ang overall angle, target margin, eksaktong tugma, at ang preview na cross-section.
  5. 5 Gamitin ang Copy result, Copy share URL, Reset, o ang recent list para magamit muli ang parehong kondisyon.

Halimbawa

12 m bench, 8 m berm, 70° face, 4 benches

Input: Bench height 12 m, berm width 8 m, face angle 70°, bench count 4, target overall slope angle 45°
Output: Overall slope angle 49.2°, margin -4.2°, required berm width 10.2 m, danger side

The same geometry in imperial

Input: Bench height 39.37 ft, berm width 26.25 ft, face angle 70°, bench count 4, target overall slope angle 52°
Output: Overall slope angle 49.2°, margin +2.8°, safe side

FAQ

Sinusukat ba ang anggulo mula sa horizontal?

Oo. Parehong ang bench face angle at ang overall slope angle ay sinusukat mula sa horizontal.

Ano ang mangyayari kapag 0 ang berm width?

Mas lalapit ang overall angle sa face angle, pero magba-babala pa rin ang tool dahil bihira itong praktikal sa field.

Paano kung hindi eksaktong matugma ang target angle?

Maaaring mapunta sa labas ng workable range ang required berm width o required face angle. Sa ganitong kaso, ipinapakita ng exact-match helper na hindi maaabot ang target gamit ang kasalukuyang geometry.

Kasama ba rito ang local regulations o safety standards?

Hindi. Geometry at unit conversion lang ang saklaw ng tool upang magamit ito sa iba’t ibang lugar nang hindi isinasama ang lokal na patakaran.

Maaari ba akong magtrabaho sa metric at imperial units?

Oo. Piliin lang ang unit na talagang ginagamit ninyo sa site.

Mga Tala

  • This tool does not cover water, blasting, rock quality, or equipment clearance.
  • If the target 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.
  • Use this for geometric checks only. A real slope design still needs a geotechnical review.
