Underground Operations

Mine communication that clears safety checks.

Relay coverage and rugged radios for branching underground operations where certification comes first.

Why mining communication is different
What makes mines harder than tunnels
Multi-branch roadways
Signals cannot travel cleanly around turns, intersections and multiple working faces.
Unlike a single tunnel, mine networks branch in multiple directions. Each branch needs its own coverage path.
Explosive atmospheres
Ordinary electronic devices may not be permitted underground without required certification.
In regulated mining environments, devices must meet specific safety approvals before they can be deployed. This applies to radios as much as any other equipment.
Moving work faces
Coverage planning changes as excavation areas move deeper.
Static infrastructure cannot follow an advancing work face. Communication coverage needs to be repositionable as operations develop.
Emergency evacuation
Supervisors need a fast way to reach all underground teams when conditions change.
In an incident, the ability to broadcast an alert to every person underground in seconds is not a feature - it is a safety requirement.
Why standard solutions fall short
Ordinary radios
May not be permitted in hazardous underground areas without the required Ex or mining safety certification. Using uncertified devices in regulated zones is a compliance risk.
May not be compliant for regulated mines
Fixed repeater systems
Require permanent installation and power cabling. Cannot follow the work face as it advances. Re-installation takes time that active mining operations rarely have.
Cannot move with advancing operations
Cellular / PoC radios
Depend on 4G/5G coverage underground. Most active mine roadways and working faces have no cellular signal available.
No network underground

Coverage is not enough.
The equipment must be safe
to take underground.

Relay coverage reaches branches and work faces. Certified devices keep the deployment aligned with mine safety rules.

How it works

Coverage across every roadway
and working face.

Self-organizing relay nodes extend communication from the surface through the main roadway and into each branch.

Planning information

What to confirm before deployment.

Mining communication planning starts with site type and certification requirements. The more clearly you can describe your environment, the faster we can recommend the right setup.

Mine type Coal, metal, non-metal or other underground operation - affects certification requirements and recommended devices
Country / region Certification standards vary by market - ATEX, IECEx, MA/KA, MSHA or local mine safety approvals if applicable
Hazardous conditions Gas, dust, methane risk or other explosive atmosphere classification, if applicable to your site
Roadway layout Main roadway length, number of branches, levels and active working faces
Team & operations Number of underground personnel, roles (miners, supervisors, inspection, rescue) and shift patterns
Existing system Current radios, repeaters, leaky feeder, dispatch platform or other communication infrastructure in use
