Mining-Related Infrastructure & Subsidence Monitoring
Mining-induced subsidence and ground movement can quietly compromise mine planning, conveyors, pipelines, haul roads, rail corridors, bridges, and plant foundations long before visible damage appears.
Kurloo delivers continuous, geodetic-grade 3D displacement monitoring to detect early movement, protect critical production assets, and strengthen subsidence risk management across active and legacy operations.
The Kurloo GNSS system establishes an absolute geodetic reference frame for monitoring, independent of local ground deformation that can compromise relative systems.
The Challenge of Monitoring Subsidence Around Infrastructure
Underground extraction, historic workings, and ground consolidation can influence broad surface areas over time.
The operational challenge is to:
- Track gradual vertical settlement and lateral strain
- Protect production-critical transport and processing corridors
- Maintain compliance with Ground Control and Extraction Plan commitments
- Reduce exposure of personnel in high-risk zones
Traditional campaign survey or isolated monitoring can miss subtle acceleration or developing strain patterns between inspections.
Continuous 3D monitoring strengthens both operational awareness and regulatory confidence.
How Kurloo Is Applied
Kurloo adds a geodetic monitoring layer across infrastructure corridors and subsidence zones:
- Stable control benchmarks outside the area of influence
- Profile lines across longwall panels and transport corridors
- Asset-specific points near rail, pipelines, haul roads, and plant
- Reference points supporting InSAR, levelling, LiDAR, or survey programs
All measurements are tied to a consistent geodetic frame, enabling coherent interpretation across multiple monitoring technologies.
Key Benefits of Kurloo for Mining-Related Infrastructure & Subsidence Monitoring
Detect Subsidence Before It Impacts Assets
Continuous 3D monitoring tracks settlement, tilt, and lateral movement affecting conveyors, pipelines, haul roads, rail, and plant foundations before deformation compromises integrity.
Protect Production-Critical Infrastructure
By identifying movement trends early, operators can shift from reactive repair to proactive maintenance planning, reducing downtime and operational disruption.
Reduce Exposure in High-Risk Environments
Autonomous monitoring limits routine access to active haul roads and unstable zones, enabling inspections to be prioritised based on measured risk.
Scale Monitoring with Changing Mine Layouts
Flexible deployment supports rotational and corridor-based monitoring as underground panels progress or surface layouts evolve.
Detecting Deviation Before Damage Occurs
Most adverse subsidence impacts develop progressively. Measurable precursors often include:
- Vertical settlement exceeding model predictions
- Horizontal strain between monitored points
- Increasing tilt or curvature along corridors
- Movement extending beyond predicted trough limits
- Step-change displacement following extraction phases
Continuous 3D monitoring enables earlier identification of these deviations, strengthening TARPs and impact management frameworks.
Practical Considerations & Monitoring Context
Kurloo complements InSAR, levelling, LiDAR, drones, and in-situ instrumentation by providing absolute, drift-free 3D control points.
Key considerations include:
- Typical ~2 km network range for sub-5 mm precision
- Clear sky visibility at monitoring locations
- Appropriate point density across infrastructure corridors
- Safe access for installation and maintenance
When integrated into a layered monitoring ecosystem, Kurloo strengthens interpretation and long-term confidence.
Supporting Ground Control & Subsidence Compliance Frameworks
Continuous GNSS displacement records support:
- Ground Control Management Plans
- Principal Hazard Management Plans
- Extraction Plan and Subsidence Management commitments
- Dam and water infrastructure protection requirements
Traceable 3D datasets can be integrated into modelling packages and regulatory submissions.
Learn From Real Projects
At an Australian underground operation, Kurloo was deployed along a transport corridor affected by predicted longwall subsidence. Sensors were positioned on stable reference ground and along critical infrastructure, including haul road shoulders and structural interfaces.
The network provided continuous, millimetre-scale displacement data throughout panel extraction. Movement trends were reviewed daily, allowing the site to distinguish expected settlement from anomalous behaviour. No maintenance visits were required during active mining, and the dataset formed part of the site’s defensible subsidence performance record.
Regulatory Pressure and Operational Risk
How Kurloo helped a tailings operator meet tightening GISTM-driven regulations by delivering rapid, defensible embankment monitoring — enabling early deformation detection and audit-ready compliance data under compressed timeframes.
