General

The Refinements step is only visible if in Configuration Options step option Use Extension has been enabled.

Refinements step overview for a sample project

Refinements are customized and work differently for all projects.

Refinements require custom scripts.

These custom scripts are loaded in the Extensions Source step.

Refinements are usually configured as part of the implementation process.

Refinements examples

The Refinements step displays custom inputs for Site Specific Extensions (“.sln” file imported in the Extension Source step).

Example of site extensions for configuring Drilling and Blasting in the project

 

Scripts may be used to apply:

  • Mining recovery,

  • Product recovery,

  • Product call factors,

  • Moisture balancing,

  • Topsoil calculations,

  • Loader rate factors by pit and bench,

  • Material type recategorisation,

  • Above/Below water table designation,

  • Effective Flat Haul calculations,

  • Custom Calendar Availability, etc.

Contact your Alastri support representative for assistance with Site Specific Extensions.

Errors

Unless all errors are addressed, either in the setup steps or in your custom script, the message shown below will be shown in the main viewport, and you will not be able to proceed with the project setup:

“There is no extension loaded, or the extension does not gather inputs from this benches form“.

Examples of some error messages, with recommendations on how to fix them, are given below. In the case of other errors that you can not solve yourself, you can contact Alastri support.

Note for advanced users

If you do not need the specified fields, double click on the error message - a window will appear with a detailed description of the issue, indicating the line in your custom script containing this field. If you are an experienced user with scripting skills in Microsoft Visual Studio, you can open the relevant script yourself and make changes in it. Otherwise, contact Alastri support representative.
