Release Date:
7th February 2023
KBA Summary:
This Knowledge Base Article describes the functionality of the Final Stemming Length dashboard in BlastIQ™ Insights.


BlastIQ™ Insights enables users to visualise the final stemming length compliance of holes before and after holes within a blast plan have been stemmed via the Final Stemming Length dashboard.

  • Comparison Options:
    Enable users to compare and evaluate the selected actual against the chosen design.
    • Select an Actual: 
      • Stemmed - Considers the final stemming length only of holes that have been stemmed.
      • Available - Considers the length remaining to be stemmed of holes that have actual loading and have not been stemmed.
    • Select a Design:
      • Adjusted Design - Latest loading instruction or design adjusted based on actual hole conditions.
      • Design - Original design, before adjusted by actual hole conditions.
  •  Tolerances:
    • The tolerance considered in this dashboard is the site-level deck horizon/top stemming length reporting tolerance. Read more here.
  • Compliance Score:
    • For any of the comparisons, the compliance score (%) is calculated as follows:
      Compliance Score (%) = 100*W/M
      W = within tolerance holes
      M = overstemmed holes + understemmed holes + within tolerance holes


  • All percentage values are truncated to 1 decimal place.
  • All other values are rounded to 1 decimal place.
Edge Case Scenarios
No design stemming deck Intermediate air deck

The following scenario will result in no evaluation for any comparison mode as the logic won't detect a design or final stemming length, the hole will show some 'available' values as it is loaded.
