Odpri-pit haulage

Kalkulator produktivnosti časa cikla tovornjak-žlica

Calculate cycle čas od naloži čas, haul razdalja, hitrost, and čakanje čas, then compare teoretična and dejanska produktivnost instantly.

Uporabi flota velikost sensitivity, operating stopnja comparisons, and ozko grlo oznake on the same screen.

How to read the rezultat
Haulage in odpri-pit rudarstvo is hazardous. Rezultati do not replace safety rules.
Cycle čas

The nalaganje, vožnja, and čakanje pieces are shown as one tovornjak cycle.

Flota bilanca

See whether the tovornjak side or the žlica side is limiting, along with the priporočena tovornjak število.

Vnosi are processed only in this brskalnik and are never sent to a server.

Varnostno opozorilo

  • Haulage in odpri-pit rudarstvo is hazardous. Rezultati do not replace safety rules.
  • Vsebnost, rolling resistance, tovor limits, vreme, and maintenance can change rezultati a lot.
  • Uporabi opazovano povprečna čakanje čas and operating stopnja od the lokacija.
  • Always nadaljnji lokalno law, dispatch rules, and safety procedures.

Kako uporabljati

  1. Izberite the enota system and tovor enota.
  2. Izberite preprost or podroben vožnja način, then enter naloži čas, vožnja conditions, and čakanje čas.
  3. Enter tovornjak število, žlica število, and operating stopnja.
  4. Preglej cycle čas, teoretična and dejanska produktivnost, bottlenecks, and flota velikost sensitivity.

Primer

Metrični basic case

Vnos

60 t payload, 3:00 load time, 4.0 km one-way haul, 25 km/h, 1:00 wait time, 6 trucks, 1 shovel, 85% operating rate

Izhod

cycle čas about 23.2 min, teoretična about 973 t/h, dejanska about 791 t/h, tovornjak-limited, priporočena about 8 trucks/žlica

Imperial case

Vnos

80 st payload, 3:00 load time, 2.5 mi one-way haul, 18 mph, 1:30 wait time, 5 trucks, 1 shovel, 80% operating rate

Izhod

cycle čas about 21.2 min, teoretična about 1,220 st/h, dejanska about 907 st/h, tovornjak-limited

Podroben način case

Vnos

60 t payload, loaded 4.0 km at 22 km/h, return 4.0 km at 32 km/h, 3:00 load time, 1:00 wait time, 8 trucks, 1 shovel, 90% operating rate

Izhod

cycle čas about 22.4 min, teoretična about 1,200 t/h, dejanska about 1,080 t/h, žlica-limited

Pogosta vprašanja

Is haul razdalja one-way or round trip?

In preprost način, enter one-way razdalja and the orodje doubles it internally. Podroben način lets you enter loaded and return legs separately.

What is the difference between teoretična and dejanska produktivnost?

Teoretična produktivnost assumes no čakanje čas and 100% operating stopnja. Dejanska produktivnost reflects čakanje čas and operating stopnja.

What changes when I change the operating stopnja?

Dejanska produktivnost changes linearly. The comparison tabela shows the difference od 50% to 100%.

Is the flota velikost analiza a queue simulation?

No. It is a static zmogljivost comparison that keeps the entered povprečna čakanje čas fiksno. It does not ocena queue growth automatically.

Can I switch between t and m³?

Da. Izberite the enota you actually uporabi on lokacija. The orodje does not convert by gostota, so enter the basis enota directly.

Can multilingual teams uporabi it?

Da. The page is translated od English, and URL sharing reproduces the same state.

Slovar

Cycle čas

Čas for one tovornjak to complete a polni nalaganje, haul, return, and čakanje cycle.

Payload

Povprečna naloži carried per tovornjak cycle.

Operating stopnja

Deli of scheduled čas actually used for production.

Ozko grlo

The resource or step that most strongly limits izhod.

Match faktor

Indicates the bilanca between tovornjak-side and žlica-side zmogljivost. Vrednosti blizu 1 are more balanced.

Čakanje čas

Povprečna waiting čas including queue, dump, spotting, and short delays.

Opombe

  • This orodje is a planning aid only. It is not a queue simulation.
  • Cesta vsebnost and rolling resistance are not modeled automatically. Adjust hitrost and čakanje čas to match lokacija reality if needed.
  • Enter the tovor enota used on lokacija. The orodje does not perform gostota conversion.
  • Flota velikost sensitivity keeps the entered povprečna čakanje čas fiksno.
