Haulage in open-pit mining is hazardous. Results do not replace safety rules.
Ciklo laikas

The loading, travel, and wait pieces are shown as one truck cycle.

Parko pusiausvyra

See whether the truck side or the shovel side is limiting, along with the recommended truck count.

Saugos įspėjimas

  • Haulage in open-pit mining is hazardous. Results do not replace safety rules.
  • Grade, rolling resistance, payload limits, weather, and maintenance can change results a lot.
  • Naudokite stebėtą vidutinį laukimo laiką ir naudojimo koeficientą iš aikštelės.
  • Always follow local law, dispatch rules, and safety procedures.

Kaip naudoti

  1. Choose the unit system and payload unit.
  2. Choose simple or detailed travel mode, then enter load time, travel conditions, and wait time.
  3. Enter truck count, shovel count, and operating rate.
  4. Review cycle time, theoretical and actual productivity, bottlenecks, and fleet size sensitivity.

Pavyzdys

Metrinis bazinis atvejis

Įvestis

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

Išvestis

cycle time about 23.2 min, theoretical about 973 t/h, actual about 791 t/h, truck-limited, recommended about 8 trucks/shovel

Imperinis atvejis

Įvestis

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

Išvestis

cycle time about 21.2 min, theoretical about 1,220 st/h, actual about 907 st/h, truck-limited

Išsamaus režimo atvejis

Įvestis

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

Išvestis

cycle time about 22.4 min, theoretical about 1,200 t/h, actual about 1,080 t/h, shovel-limited

DUK

Is haul distance one-way or round trip?

In simple mode, enter one-way distance and the tool doubles it internally. Detailed mode lets you enter loaded and return legs separately.

Kuo skiriasi teorinis ir faktinis našumas?

Theoretical productivity assumes no wait time and 100% operating rate. Actual productivity reflects wait time and operating rate.

Kas pasikeičia, kai pakeičiu naudojimo koeficientą?

Actual productivity changes linearly. The comparison table shows the difference from 50% to 100%.

Is the fleet size analysis a queue simulation?

Ne. Tai statinis pajėgumo palyginimas, kuriame įvestas vidutinis laukimo laikas paliekamas fiksuotas. Eilių augimo jis automatiškai neįvertina.

Can I switch between t and m³?

Yes. Choose the unit you actually use on site. The tool does not convert by density, so enter the basis unit directly.

Can multilingual teams use it?

Taip. Puslapis išverstas iš anglų kalbos, o bendrinamas URL atkuria tą pačią būseną.

Žodynėlis

Ciklo laikas

Time for one truck to complete a full loading, haul, return, and wait cycle.

Krovinys

Average load carried per truck cycle.

Naudojimo koeficientas

Share of scheduled time actually used for production.

Bottleneck

The resource or step that most strongly limits output.

Match factor

Indicates the balance between truck-side and shovel-side capacity. Values near 1 are more balanced.

Laukimo laikas

Average waiting time including queue, dump, spotting, and short delays.

Pastabos

  • Šis įrankis skirtas tik planavimui. Tai nėra eilių simuliacija.
  • Road grade and rolling resistance are not modeled automatically. Adjust speed and wait time to match site reality if needed.
  • Enter the payload unit used on site. The tool does not perform density conversion.
  • Fleet size sensitivity keeps the entered average wait time fixed.
