Mine Site Technologies is rethinking the humble cap lamp, turning the standard piece of underground gear into an integrated multi-purpose tool.
A miner’s cap lamp is more than a source of light. It is a constant companion through long hours in some of the most demanding work environments anywhere.
For Mine Site Technologies (MST), that sparked an innovative question: what if the cap lamp could take on more responsibility?
The result is the Integrated Communications Cap Lamp (ICCL) Echo, a compact, Wi-Fi-enabled device that combines a cap lamp with communication, tracking and safety functions. While it looks like a standard light, the Echo operates as a multi-purpose tool designed to make underground work more efficient and secure.
For miners, the Echo changes how they interact with both their gear and their safety systems.
Instead of relying on multiple devices, the Echo incorporates an LED cap lamp, personal emergency device (PED) messaging and Wi-Fi tracking radio frequency identification (RFID) into a single, intrinsically safe unit.
“This unified capability drives adoption and connectivity, advancing mine safety and readiness,” MST global product manager Conrad Aitken told Safe to Work.
One of the most important upgrades in the Echo is its return-path messaging capability. Traditionally, through-the-earth alerts worked in one direction only. A control room could issue a warning or an evacuation notice, but they had no way of knowing if the message was received. With the Echo, messages sent to the wearer can be acknowledged with a quick reply via the AXON Wi-Fi network. In practical terms, this turns static messages into dynamic conversations.
The ability for employees to confirm and respond improves situational awareness for surface teams and underground workers.
To further support underground safety, the Echo can be equipped with a proximity-detection module. This optional feature sends alerts when workers enter restricted zones or approach mobile machinery. For operators and nearby personnel alike, the added awareness reduces the likelihood of collisions and improves spatial coordination in confined areas.
Knowing where each worker is located underground has long been a logistical challenge. The Echo helps solve this with integrated Wi-Fi RFID tracking tags. Each unit provides real-time location data, giving control room operators and supervisors a clear picture of who is where. Whether it’s a routine drill, a shift change, or an emergency evacuation, the system improves planning and execution.
According to Aitken, its dual role as both lamp and tracker helps teams “manage safety more effectively without deploying additional PPE [personal protective equipment]”.
Battery performance has also been addressed. The Echo runs on a rechargeable lithium-ion battery that offers over 24 hours of continuous use. That kind of longevity helps to ensure the device remains functional throughout even extended shifts or delays underground.
Some of Echo’s practical benefits go beyond the technology itself for mine operators.
Reducing the number of devices each worker carries means less maintenance, fewer charging stations, and fewer potential points of failure. It also simplifies training. With only one device to learn, crews can on-board more quickly and operate more confidently. Over time, that supports a stronger and more consistent safety culture across the site.
“From a safety management standpoint, consolidating critical functions into a single unit like the ICCL Echo reduces complexity and streamlines compliance,” Aitken said.
Looking to the future, MST views the Echo as a flexible platform that can evolve with the needs of modern mining.
“As mining becomes more digitised, devices like Echo will evolve to collect richer environmental data, support analytics, and integrate with autonomous systems,” Aitken said.
The idea, he said, is to turn the lamp into a broader health and safety hub that supports both individual wellbeing and operational insight.
“This aligns with MST’s broader vision of a connected mine, where wearable tech drives smarter decisions and safer operations underground,” Aitken said.
