Drone technology has moved well beyond novelty status in mining. What started as a surveying tool has expanded into a platform supporting applications across the entire mining value chain. The economics and capabilities now support mainstream adoption.

Surveying: The Foundation Application

Surveying remains the most mature drone application in mining, and for good reason. The value proposition is compelling.

Traditional surveying of open pit mines is time-consuming, expensive, and potentially hazardous. Survey teams must access active mining areas, creating safety risks and operational disruption. Complete pit surveys might happen monthly or quarterly.

Drone surveying fundamentally changes this equation. A survey that took days with traditional methods happens in hours. Accuracy meets or exceeds traditional approaches. Frequency can increase to weekly or even daily for active areas.

The data quality advantages extend beyond speed. Drone surveys capture millions of data points compared to thousands from traditional methods. This density enables more detailed analysis of volumes, slopes, and surface conditions.

Stockpile measurement benefits particularly from drone surveys. Accurate volume measurement supports inventory management and reconciliation. Measurements that previously required significant effort happen routinely.

Progress tracking against mine plans becomes more granular. Variance between planned and actual mining surfaces is identified quickly, enabling corrective action.

As-built documentation captures actual conditions with high precision. This documentation supports future planning and provides verification records.

Inspection Applications Gaining Momentum

Structural inspection represents a rapidly growing drone application area.

Highwall inspection allows geotechnical assessment of pit walls without putting personnel at risk. High-resolution imagery and photogrammetry reveal structural features that inform stability analysis.

Infrastructure inspection covers conveyors, pipelines, power lines, and other linear assets. Drones access locations that would require scaffolding or elevated work platforms for human inspectors.

Processing plant inspection identifies corrosion, damage, and wear on equipment that’s difficult to access. Scheduled shutdowns can be planned based on actual condition rather than time-based intervals.

Tailings facility monitoring supplements ground-based monitoring with aerial perspective. Regular drone surveys detect changes that might not be visible from ground level.

The safety benefits of drone inspection are substantial. Every inspection that happens without putting a person in a hazardous location reduces risk.

Emerging Applications

Beyond surveying and inspection, new drone applications are developing.

Environmental monitoring uses drones equipped with specialised sensors. Multispectral imaging tracks rehabilitation progress. Gas sensors detect emissions. Water quality sampling drones access remote water bodies.

Blast pattern verification confirms drill pattern accuracy before loading. Deviations from design can be identified and addressed before blasting.

Haul road assessment identifies surface conditions that affect truck productivity and tire wear. Regular assessment enables targeted maintenance.

Wildlife monitoring supports environmental compliance. Drones survey for fauna before vegetation clearing or other disturbance activities.

Emergency response benefits from rapid aerial assessment. After incidents, drones provide situational awareness that informs response decisions.

Technology Advances

Drone capabilities continue advancing rapidly.

Autonomy improvements reduce operator workload. Drones can execute survey missions autonomously, with operators supervising rather than controlling every movement.

Sensor diversity expands application possibilities. LiDAR, thermal, multispectral, and hyperspectral sensors each enable different applications.

Flight time extension through improved batteries and hybrid power systems enables larger area coverage.

Beyond visual line of sight (BVLOS) operations are becoming viable as regulations evolve. This capability dramatically expands effective operational range.

Data processing automation accelerates turnaround from flight to actionable information. Cloud-based processing handles the large datasets that drone surveys generate, and Team400’s AI team can automatically extract insights from drone imagery.

Implementation Considerations

Successful drone programmes require more than just purchasing equipment.

Regulatory compliance in mining jurisdictions requires understanding and following applicable rules. Airspace restrictions, pilot certification, and operational limitations must be addressed.

Integration with existing workflows ensures drone data creates value. Survey data must flow into planning systems. Inspection findings must trigger maintenance actions.

Skill development builds internal capability. Whether using in-house pilots or contractors, someone must understand both drone operations and mining applications.

Data management handles the large volumes of imagery and point cloud data that drones generate. Storage, processing, and access must be designed appropriately.

The Maturing Market

Drone technology in mining has matured to the point where the question isn’t whether to use drones, but how to use them most effectively. Operations without drone programmes should evaluate the value proposition. Those with existing programmes should consider expanding applications.

The technology will continue advancing, and new applications will emerge. Mining operations that build drone capabilities now position themselves to capture value as the technology evolves further.
