Underground Communication-System Monitoring
Monitor the availability and performance of fibre, leaky-feeder, Wi-Fi, private LTE/5G and underground radio infrastructure.
What this connected-mine application does
Monitor the availability and performance of fibre, leaky-feeder, Wi-Fi, private LTE/5G and underground radio infrastructure.
The practical objective is not simply to collect more data. It is to establish a trustworthy measurement chain, detect abnormal conditions, preserve the relevant operating context and route information to the team that can act on it.
- Node, access point and repeater availability
- Signal strength and coverage indicators
- Uplink, downlink and channel utilisation
- Power supply, UPS and battery state
- Temperature, ingress and enclosure alarms
- Backhaul status and redundancy path
| Primary field devices | Network-management interfaces; SNMP-capable switches and radios; RF monitoring points; UPS and DC power sensors; Central network-operations dashboard |
|---|---|
| Data update pattern | Event-driven alarms with periodic telemetry. Critical events should be timestamped and transmitted immediately where the communications design permits. |
| Connectivity options | Industrial Ethernet, fibre, Wi-Fi, leaky-feeder, LoRaWAN or private LTE/5G as site conditions permit. |
| Alarm and analytics | Alert on node loss, backhaul failure, degraded coverage, UPS low battery, enclosure condition or loss of redundancy. |
| Common integration | Common interfaces include dry contacts, 4–20 mA, Modbus RTU/TCP, OPC UA, EtherNet/IP, CAN/J1939, MQTT, SNMP or REST APIs where supported by the source equipment. |
| Data continuity | Timestamp at the edge, monitor signal quality and device health, and use store-and-forward buffering so short network outages do not create silent data gaps. |
| Environmental design | Use mine-suitable enclosures, protected cabling and glands, appropriate ingress/impact resistance, and certified equipment wherever the hazardous-area classification requires it. |
A five-layer implementation pattern
Measure
Approved sensors and machine interfaces capture the required physical or operating state.
Control locally
Existing PLCs, protection and safety systems retain their required local authority.
Acquire at edge
A rugged gateway timestamps, buffers, normalises and validates incoming data.
Transmit securely
Mine communications carry telemetry and alarms with health and quality monitoring.
Visualise and integrate
Dashboards, historians and APIs support response, maintenance and reporting.
Where the solution can be applied
- Portal and shaft
- Main haulage and production district
- Refuge and emergency communication points
- Control room and surface data centre
Potential benefits
- Faster identification of coverage and hardware failures
- Visibility of backup power condition
- Prioritised maintenance by operational impact
- Evidence for communication availability
- Better support for tracking, video and automation
Design details that determine success
- Separate operational technology from enterprise networks
- Monitor without exposing unsafe control access
- Plan coverage for changing mine geometry
- Test emergency communications independently of dashboards
Alert on node loss, backhaul failure, degraded coverage, UPS low battery, enclosure condition or loss of redundancy. Dashboard alerts, remote notifications and analytics should complement—not replace—certified protection, local interlocks, emergency procedures, statutory inspections and competent decision-making.

Implementation questions
Can Underground Communication-System Monitoring connect to existing PLC, SCADA or mine systems?
Usually, yes. The preferred approach is to reuse approved source data and add isolated field instrumentation only where required. The final interface depends on available protocols, network segregation, data ownership and the source equipment vendor.
Does the IoT layer replace local protection or safety controls?
No. Protection relays, safety PLCs, emergency stops, gas trips, fire systems and other approved local functions remain the primary safety and control layer. IoT adds visibility, history, notifications and decision support.
What happens when underground communications are interrupted?
Critical local functions continue independently. A suitable edge gateway buffers timestamped data, raises a communications-health alarm and forwards retained records after the connection returns.
How are sensors and alarm levels selected?
Selection starts with the mine risk assessment, required decision, environmental classification, measuring range, response time, maintainability and applicable rules. Alarm and trip levels must be approved for the specific site and jurisdiction.

Engineering note: Instrument selection, hazardous-area certification, alarm limits, interlocks and network architecture must be validated against the mine risk assessment, applicable legislation, equipment approvals and site operating procedures.
