Per-Stope Analysis

Purpose

Assessment of performance on a per stope basis. The most basic form of analysis used to identify broad trends, for example, comparing overbreak of stopes from different regions in the mine.

Analysis options consist of:

• 3D view
• Tables (regular and LITE version)
• Charts:
  • A vs B Chart
  • Cumulative Chart (Two Series)
  • Cumulative Chart (Group By)
  • Cumulative Log Chart (Group By)
  • 3D Chart
  • Design vs Mined
    • This chart allows to visualise design vs mined volume with OB and UB volumes plotted as lines above (OB) and below (UB) the stope point.

Design vs Mined Chart

At a per stope resolution, broad parameters can be queried and are listed here:

• Design, Mined or Fill volume
• First or Last blast date
• Stand-up time (days)
• Different tags (access, Method, region, sequence)
• Position (X,Y,Z)
• Stope performance
  • OB (volume, %, rock, fill)
  • UB (volume, %, rock, fill)
  • OB + UB (%)
  • Recovered (%)
  • Compliance to design (%)
    • $\frac{Design - UB}{Design + OB}$
  • Volume difference (%)
    • $\frac{Mined - Design}{Design}$
