How to read the rezultat
Haulage in deschide-pit minerit is hazardous. Rezultate do not replace siguranță rules.
Ciclu timp

The loading, travel, and wait pieces are shown as one camion ciclu.

Fleet balanță

See whether the camion side or the încărcător side is limiting, along with the recommended camion count.

Siguranță notificare

  • Haulage in deschide-pit minerit is hazardous. Rezultate do not replace siguranță rules.
  • Grad, rolling resistance, payload limits, weather, and maintenance can change rezultate a lot.
  • Folosește observed average wait timp and operating rate from the site.
  • Always follow local law, dispatch rules, and siguranță procedures.

How to use

  1. Choose the unitate system and payload unitate.
  2. Choose simple or detailed travel mode, then enter încarcă timp, travel conditions, and wait timp.
  3. Enter camion count, încărcător count, and operating rate.
  4. Review ciclu timp, theoretical and actual productivitate, bottlenecks, and fleet dimensiune sensitivity.

Exemplu

Metric basic case

Intrare

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

Rezultat

ciclu timp about 23.2 min, theoretical about 973 t/h, actual about 791 t/h, camion-limited, recommended about 8 trucks/încărcător

Imperial case

Intrare

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

Rezultat

ciclu timp about 21.2 min, theoretical about 1,220 st/h, actual about 907 st/h, camion-limited

Detailed mode case

Intrare

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

Rezultat

ciclu timp about 22.4 min, theoretical about 1,200 t/h, actual about 1,080 t/h, încărcător-limited

Întrebări frecvente

Is haul distanță one-way or rotund trip?

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

What is the difference between theoretical and actual productivitate?

Theoretical productivitate assumes no wait timp and 100% operating rate. Actual productivitate reflects wait timp and operating rate.

What changes when I change the operating rate?

Actual productivitate changes linearly. The comparison tabel shows the difference from 50% to 100%.

Is the fleet dimensiune analysis a queue simulation?

Nu. It is a static capacity comparison that keeps the entered average wait timp fixed. It does not estimează queue growth automatically.

Can I switch between t and m³?

Da. Choose the unitate you actually use on site. The instrument does not convertește by densitate, so enter the bază unitate directly.

Can multilingv teams use it?

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

Glossary

Ciclu timp

Timp for one camion to complete a full loading, haul, return, and wait ciclu.

Payload

Average încarcă carried per camion ciclu.

Operating rate

Partajează of scheduled timp actually used for production.

Bottleneck

The resource or step that most strongly limits rezultat.

Match factor

Indicates the balanță between camion-side and încărcător-side capacity. Values near 1 are more balanced.

Wait timp

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

Nutes

  • This instrument is a planificare aid only. It is not a queue simulation.
  • Drum grad and rolling resistance are not modeled automatically. Adjust speed and wait timp to match site reality if needed.
  • Enter the payload unitate used on site. The instrument does not perform densitate conversion.
  • Fleet dimensiune sensitivity keeps the entered average wait timp fixed.
