About the Project
In the demanding environment of underground mining, maintaining visibility of personnel and assets is critical for both safety and efficiency. IoT Automation, in partnership with Navigine, deployed a converged digital backbone that unifies lighting and positioning. By embedding BLE tracking technology directly into FireFly and DragonFly luminaires, the project eliminated the need for a secondary tracking network. This solution delivers robust zone-level accuracy across 1,200m tunnel segments, ensuring that the "digital backbone" of the mine is as resilient as the infrastructure itself.
Technology used for the mining project:
- Navigine RTLS Platform (Monitoring & Analytics)
- IoT Automation FireFly & DragonFly Luminaires
- Integrated BLE/Wi-Fi Mesh Modules
- RS-485 Hardline Backbone
The Challenge
Underground mining tunnels present a unique set of logistical hurdles. Traditional tracking systems often require a dedicated network of gateways, which increases CAPEX and creates maintenance complexity. In a deep-tunnel environment:
-
Infrastructure Fragmentation: Maintaining separate systems for lighting and tracking is costly and prone to failure.
-
Connectivity Gaps: Standard wireless signals struggle in linear, metallic, and rock-heavy environments.
-
Power Reliability: In the event of a power outage, losing visibility of personnel creates a significant safety vacuum.
Project Impact
-
Reduced CAPEX: Elimination of dedicated tracking hardware by using lighting as the mesh.
-
100% Visibility: Continuous tracking of workers even during power failures via internal UPS.
-
Operational Speed: Drastic reduction in asset search times for pumps, loaders, and vehicles.
Why the Mine Needed Unified Mining Navigation & Safety?
The mine's operational team required a high-reliability, low-maintenance system to oversee underground movement. They sought a solution that could provide:
-
Unified Infrastructure: A single "converged" system for both illumination and positioning.
-
Resilient Uptime: Integrated battery backups to maintain tracking during emergencies.
-
Zone-Level Accuracy: Reliable room and zone detection for complex, multi-section tunnels.
-
Safety Automation: The ability to trigger visual alerts (lighting changes) based on real-time software events.
The Converged Infrastructure: A Solution for Unified Mining
To address these needs, the team deployed the FireFly & DragonFly Lighting Mesh. This system treats every light fixture as a positioning node. Using a robust RS-485 architecture, the system supports data transmission across 1,200m run lengths, making it ideal for the linear nature of mining tunnels. The lighting hardware detects BLE tags worn by personnel, sending that data back to the Navigine RTLS Platform for real-time visualization.

Why Choose a Unified Backbone?
Choosing a converged infrastructure was a strategic move for the mine’s R&D and Safety departments:
-
Cost Efficiency: By embedding radios in luminaires, the mine bypassed the cost of a standalone tracking network.
-
Simplified Maintenance: One set of hardware provides two critical services (Light + Data).
-
Long-Distance Reliability: The RS-485 hardline ensures data remains immune to the interference typically found in deep-earth operations.
Why Choose Navigine RTLS Platfrom for Unified Mining Navigation & Safety?
The Navigine Software Suite acts as the "Intelligence Layer." It ingests raw signal data from the lighting mesh and converts it into actionable insights. Through the Navigine Dashboard, operators can manage Zone Geofencing to detect unauthorized entry into restricted areas and audit Movement History for regulatory compliance. Its ability to trigger bi-directional safety alerts—flashing lights Red for evacuation or Green for safe routes—turns raw data into life-saving action.
Why IoT Automation Hardware?
IoT Automation’s FireFly luminaires are engineered for the extreme. Featuring an internal LiFePO4 UPS, these lights ensure that the "digital backbone" never goes dark.
-
Integrated Intelligence: BLE/Wi-Fi mesh modules are built-in, not tacked on.
-
Durability: Designed to withstand the dust, moisture, and vibration of active mining.
Visual Communication: The hardware supports bi-directional control, allowing the software to change light colors during emergencies.
The Advantages of Unified Mining Navigation & Safety
-
Sub-Room Accuracy: Reliable zone detection ensures you know exactly which tunnel segment a worker is in.
-
Automated Compliance: Digital logs replace manual check-ins, simplifying regulatory safety reporting.
-
Bi-Directional Safety: The system doesn't just "watch"—it communicates by using the lights to guide workers during an evacuation.
-
Optimized Asset Use: Real-time tracking of loaders and vehicles reduces idle time and equipment misplacement.
The Results
The deployment proved that lighting is the most logical and cost-effective carrier for industrial IoT. The pilot successfully demonstrated zero-latency zone detection and maintained 100% uptime during simulated power failures. By turning the mine’s illumination into an intelligent mesh, the facility has achieved a "future-proof" foundation that balances worker safety with massive CAPEX savings.
