Capital Costs

To access this screen:

  • Optimization task bar >> Scheduler >> Capital Costs.

Define Capital Costs for the Scheduler, MAO and MFO. You define obstacle removal costs prior to pit optimization and all other capital costs prior to scheduling.

Costs can be defined on a per-pushback and per-period basis, with each category defined in a separate table.

Note: You can specify a maximum of 50 rows for pushbacks and time periods.

To define capital costs for the scheduler:

  1. Display the Capital Costs screen.

  2. Use the Capital costs by pushback table to specify for each Pushback Index, the capital Costs on the day when the mining of the pushback begins; enter the investment amount.

  3. Similarly, for per-period costs, use the lower table to specify the time Period index, and the money spent on the first day of the that time period. For MFO, check if the timing of the expenditure depends on the mining rate; if so, MFO will adjust (move to an earlier date) the timing proportionally to compensate for the increase in mining rate affecting Net Product Value calculations, and overall optimization results.
