This technical guide lays out the Underground Operational KPIs that truly shape performance in hard-rock mining. Plenty of sites track tonnes and meters, but the real story sits inside the KPIs that reveal how smoothly the underground cycle is actually running. Advance consistency, drill readiness, stope condition, dilution control, and backfill timing all play a huge role in whether a mine stays on track or slips behind without anyone noticing in the moment.
The Underground KPI Library breaks each of these down in simple, practical language. It explains what every KPI means, how it connects to the mining cycle, and why it matters for supervisors, miners, drillers, engineers, and planners. Development advance shows whether access to future stopes is protected. Production drill meters show whether your firing schedule is safe. Mining recovery and dilution tell you if you are pulling value or losing it. Backfill compliance reveals if your sequence is about to bottleneck.
Here is the thing. When these KPIs are measured correctly and used shift by shift instead of only at month end, teams spot problems early. Slower advance warns of access delays. Low drill meters reveal equipment or crew constraints. Rising dilution uncovers drilling or ground issues. Backfill delays signal that an entire mining block may soon stall. This guide gives teams the clarity to act before the losses appear in the production report.
With GroundHog’s connected ecosystem bringing production data, drill logs, stope plans, shift actuals, and maintenance inputs together in one place, mines can validate these KPIs in real time and make decisions based on what is happening right now.
This guide covers:
- How to track development, stope readiness, and drill performance
- How to calculate dilution, recovery, and ore tonnes correctly
- How to use backfill and cycle KPIs to keep the mining sequence flowing
- How GroundHog gives operations a single source of truth for underground performance
