Calendar ratio values by period.

Stockpiles

Enter capacity limits and turnover triggers.

Use the Delete key in Stockpile rows to reset limits and triggers.

Force Mode

Can force a stockpile into build mode, reclaim mode, or off entirely. This allows the user another level of control over stockpile blending.

Turnover Trigger

  • Turnover triggers only apply to Blended and Mutex stockpile types.

  • If a stockpile hits the turnover trigger during the period, it switches from building to reclaiming.

Capacity Limit

  • Stockpile capacity is set by the Chunk Template in Stockpiles Setup.

  • Chunk Template capacity is the sum of chunks in Stockpile Chunks.

  • If the Capacity Limit is set to less than the Total Capacity, then the stockpile will pause building (it will not reclaim).

  • If the Capacity Limit is set to greater than the Total Capacity, then it has no effect.

Stockpile Sets

For mutex stockpile sets, Force Mode can force all stockpiles in a set into build mode or reclaim mode.

To determine which stockpile will be reclaimed next, give it a higher priority in the mutex stockpile set or use -1 to force it to immediately switch to reclaiming the chosen stockpile.

Crushers

Enter crusher rates by period.

Calendar crusher rates.

Dumps

Optionally enter dump limits in the calendar. Note that dumps automatically detect their own volume, so manually constraining their capacity is rarely required.

Calendar dump limits.

Default Rates

Enter default rates for non-mining activities. These are used to put a cool-down timer between when a blast is exposed and when it can be mined in the Mining Mode schedule runs.

Calendar default ancillary rates.

Agent Priorities

If two agents are assigned to the same block, the agent with a lower priority will stop and wait for the agent with a higher priority.

Calendar agent priorities.

Agents

Enter agent rates, number of allowed trucks and maximum instantaneous trucks. Instantaneous trucks will be the maximum allowed trucks at an instance for a particular transaction set.

Calendar agent rates.

Trucks

Enter truck numbers and time usage.
