How the Different Hours are Calculated

note.gif (1017 bytes)

The Period Hours grid column contains the duration (period length) as defined in the calendar dialog.

 

Period Hrs, Downtime Hrs, Available Hrs and Lead Duration are reported for each Activity (e.g. Loading). Operating Hrs, Remaining Hrs and Capacity are reported per fleet.  Fleet capacity is calculated as follows:

  • Period Hrs = Calendar Hrs

  • Downtime Hrs = [Mine Standby + Planned Maintenance]

  • Available Hrs = [Period Hrs – Downtime Hrs]

  • Remaining Hrs (Haul Truck) = [Available Hrs – (Truck Hrs /Utilisation)] x Utilisation

  • Remaining Hrs (Machines)  = [Available Hrs – (Lead Duration + Working Duration )] x Utilisation

  • Fleet Capacity (Machines) = Remaining Hrs x Unit Rate x Number of units

  • EFH Loaded = the total EFH loaded distance covered by that truck class over a period
    (loaded trip time x loaded flat haul speed x number of trips)

  • EFH Empty = the total EFH empty distance covered by that truck class over a period
    (unloaded trip time x unloaded flat haul speed x number of trips)
     

Where the fleet consists of more than one machine the fleet can be thought of as a number of machines working in parallel. For example if you require to move 10,000 tonnes/day with 1 Machine rated at 2,000 tonnes per operating hour and a utilisation of 50%, the fleet capacity is calculated as follows:

Period Hrs = 24 hrs
Downtime = 0 hrs
Available Hrs = 24  

Operating Hrs = 10,000 tonnes /[2,000 tph x 1 Unit x 50%] = 10 hrs
Remaining Hrs = 24 – 10 = 14 hrs
Fleet Capacity = 14 Hrs x 2,000 tph x 50% = 14,000 tonnes



If you now assume you have 2 machines in the fleet and a delay of 2 hrs is inserted or included for a safety meeting then the fleet capacity will be computed as follows:

Available Hrs = 22 hrs
Operating Hrs = 10,000 tonnes /[2,000 tph x 2 Units x 50%] = 5 hrs
Remaining Hrs = 22 -5 = 17 hrs
Fleet Capacity = 17 hrs x 2,000 tph x 2 units x 50% = 34,000 tonnes

 

The actual start and end times for the Time Period, Non Work time and Planned Maintenance events are used to determine the Scheduled Hours. These events may overlap and this is taken into consideration when calculating the available operating hours.

The capacity of a Machine Class for a given time period is determined from the available operating hours and the rated capacity. The Rated capacity is entered in the Haul Truck Settings.
