Define Planning Model

To access this screen:

  • Activate the Setup ribbon and select Model >> Define.

Define Planning Model.

Defining one or more planning models for your project.

Activate the Setup ribbon and select Model | Define.

Studio OP uses mine planning block models to evaluate the mining block reserves and assign the mining blocks with attributes such as rocktype, density and grade. This enables the blocks to be scheduled to meet planning targets. Planning models are added to your database and assigned to pits using the Define Planning Model task.

A planning model is usually based on a reserve model and will have been created from a strategic planning exercise, for example, by using Studio NPVS+.

Multiple planning models can be defined and validated in a project. They are then available to be assigned to pits.

Note: Where multiple models have been loaded, you can update the attributes list by selecting a model description in the list at the top of the screen.

Note: Field assignments are listed in alphabetical order.

Note: The path length in a linked file is limited to 56 characters. Any local or network path that exceeds this limit will not be interpreted correctly. Mapping a network drive to the local system is recommended in this scenario as this can be used to reduce the length of the path that is required.

Activity steps:

  1. Display the Define Planning Model screen.

  2. Review the Define Planning Block Models list at the top of the screen:

    • To create a copy of a block model within your project database for later assignment to a pit, choose Add Copy and browse for a model file.

    • To link to a remote block model (outside of the current database), for example an approved model referenced by multiple pits or projects, click Add Link and select a file.

  3. Once a model has been defined, map the model fields to a particular description (for example, does the field represent density, rock type, grade and so on).

  4. Choose how model fields are evaluated (if appropriate) using the Evaluate menu to pick Additive, Weighted or Dominant. Alternatively, Ignore the field during evaluation.

  5. Decide if the field values are Weighted according to Volume or Mass.

  6. You can apply a secondary weighting using another model key field if required, using the Weight2 menu.

  7. Decide on a Label to be used when reporting evaluated results for the target field. For example, "%".

  8. Assign a model to be used for pit reserve calculations, for each pit. 

    Note: Every pit must be assigned a model.
