# Mine Rehabilitation & Closure Monitoring

 Defensible 3D GNSS Monitoring for Long-Term Landform Performance Mine closure no longer ends at reshaping and revegetation. Operators must demonstrate that rehabilitated landforms remain stable, safe, and compliant for years — sometimes decades — after active mining ends.

Kurloo provides defensible monitoring through continuous 3D GNSS displacement data, helping rehabilitation and closure teams verify settlement behaviour, detect emerging instability, and support regulator sign-off with traceable evidence.

The Kurloo GNSS system establishes an absolute geodetic reference frame for monitoring, independent of local ground deformation that can compromise relative systems.

 Jump to Content ## The Operational Reality of Rehabilitation

Rehabilitated landforms continue to move long after reshaping. Settlement, consolidation, slow creep, erosion, or differential movement can develop gradually — often beneath vegetation or surface cover.

Regulators increasingly require verifiable evidence that landforms meet completion criteria for stability, erosion control, and long-term performance. Periodic survey or visual inspection alone is rarely sufficient.

Closure teams prefer continuous, auditable 3D displacement records that demonstrate performance against design assumptions and support defensible sign-off.

## How Kurloo Is Applied

Kurloo adds an absolute 3D monitoring layer at key rehabilitation zones:

- **Slopes, berms, and plateaus —** tracking long-term settlement and lateral movement
- **Capped tailings and encapsulated waste —** monitoring consolidation and surface response to loading
- **Transition and interface zones —** detecting differential movement between new and existing ground
    
    - **Between survey campaigns —** providing continuous displacement data to complement less precise drone or aerial LIDAR models

Because positions are tied to a consistent geodetic frame, Kurloo can also act as ground truth for InSAR, radar, and survey control networks.

## Key Benefits of Kurloo for Mine Rehabilitation & Closure Monitoring

 ### Verify Long-Term Landform Performance

Continuous displacement monitoring confirms whether rehabilitated dumps, capped tailings, and reshaped landforms are performing as designed over multi-year closure horizons.

 ### Detect Post-Closure Instability Early

Slow creep, settlement, or slumping can be identified well before visible failure, supporting proactive intervention during closure and care-and-maintenance phases.

 ### Reduce Survey Mobilisation During Closure

Autonomous GNSS monitoring eases reliance on specialist survey resources while maintaining consistent, auditable displacement records.

 ### Support Regulatory Sign-Off and Relinquishment

Traceable monitoring data strengthens environmental reporting and regulator confidence when progressing toward mine closure and long-term stewardship outcomes.

## Detecting Instability Before It Becomes Non-Conformance

Rehabilitation non-conformances often begin as subtle deformation: localised settlement along drainage lines, gradual divergence across slopes, or persistent movement near capped zones.

Continuous 3D displacement monitoring enables early identification of:

- Differential settlement across reshaped surfaces
- Accelerating lateral movement on rehabilitated slopes
- Subsidence bowls linked to cover system performance
- Step-change deformation following rainfall or dynamic events

Early detection supports timely investigation and stronger evidence for compliance reporting.

## Practical Considerations & Monitoring Context

Kurloo complements in-situ instrumentation, drone surveys, LiDAR, or InSAR. Its role is to provide absolute, drift-free 3D displacement that strengthens interpretation across the monitoring ecosystem.

Key considerations include:

- Typical ~2 km network range for sub-5 mm performance
- Clear sky visibility for optimal measurement
- Appropriate network density in high-risk zones
- Safe access for installation in steep or revegetated areas

When integrated with other technologies, Kurloo provides a coherent, long-term deformation reference for rehabilitated landforms.

## Case Study: Proven in Australian Rehabilitation Projects

Kurloo has been deployed on rehabilitated tailings and waste landforms in Australia to monitor settlement during capping and post-mining reshaping. Continuous, sub-5 mm precision displacement records have supported geotechnical assurance, milestone reporting and closure planning.
