Multimine Scheduler: Quick Start

1. Create a project
2. Select the Multi-mine option:
   
   [pic 1]
3. Import two or more block models using the same commands and following the same procedures as for importing block models into projects. Note that you can import only one model into a single-mine project while you can import as many as you want into a Multimine project (system resources permitting).
4. Select a mine using the drop-down list on the Optimization ribbon and define Settings for the Economic Model. Repeat the operation for all mines listed.
5. Select [All Mines] and run the Economic Model.
6. Customize all mines and mine specific reports. Iterate through [All Mines] and mine names and, for each selection choose the Reports | Options (Optimization ribbon) command and set your options.
7. With [All Mines] active, select Settings in the Pit Optimization group of the Optimization control bar.
8. Set your NPV parameters and choose your sequencing options.
9. Select a mine using the ribbon menu and, again, choose Settings and set the parameters and options for each mine.
10. Run the Ultimate Pit solver (mine selection is not relevant here).
11. Select a mine using the ribbon menu, select Settings in the Pushbacks group of the Optimization control bar and set the pushback parameters for this mine.
12. Repeat for all remaining mines.
13. Run pushbacks (mine selection is not relevant here).
14. Select [All Mines], select Settings in the Scheduler group of the Optimization control bar and set the scheduling parameters.
15. Run the Scheduler (mine selection is not relevant here).
16. Select Settings in the Allocation & Flow group of the Optimization control bar and set MAO/MFO parameters.
17. Run MAO or MFO (mine selection is not relevant here).

Other Options

Data Import

You can import surfaces and boundaries into Multimine projects in the same way as you import them into single mine projects. Keep in mind that all this data is mine specific and MMS will associate it with the selected mine unless the data is incompatible with the given mine model, in which case the import will fail.

Pit Optimization

You can generate 3D slope regions for some or all mines; again the command depends on the toolbar selection. Similarly, you can import or digitize pit limits and obstacle boundaries for specific mines.

Scheduling

The options for scheduling include defining mine specific capital costs, haulage destinations and specifying pushback inputs other than the default input OES generated by the Pushback Generator. You can specify pushback input for some or all mines; the mines for which the input is not specified will use the default input. Another option is to customize pushback dependencies for some or all mines.

MAO/MFO

MAO and MFO can “own” the economic settings or use the current economic model settings (see Update Economics).A

lthough the settings for some mines can be identical to economic model settings and be different for others, MAO/MFO either owns all settings or none.

Be aware that if you selected Use these settings on the Options tab of the Economic Settings dialogs for at least one mine and then reverted to Use Economic Model settings box for this or any other mine, you will lose any MAO-specific settings that you have defined.

Using the Clipboard and the Project Map Control Bar

Multimine projects make for a more challenging environment for copying settings between documents than for a single mine project; nevertheless, the following operations are supported:
