Mines need to work on the principle of safety above all else, especially when operating large machinery and heavy vehicles.

Sophisticated proximity alert systems and proximity detection devices are an essential investment to avoid collisions in the hazardous mining environment, between both equipment and personnel.


Restricted access, reduced visibility and small spaces can all increase the risk of collision between machines and personnel. Add operator fatigue and poor decisions into the mix, and equipment collision is one of the most hazardous aspects of mining.

In fact, studies by the United States National Institution for Occupational Safety and Health (NIOSH) have found that more than 40% of the most serious injuries in the mining industry involved accidents classified as struck-by or caught-in machinery and powered haulage equipment.

Reducing the Risk of Collision With Proximity Alert Systems

Leading supplier of mining safety equipment throughout North America, Carroll Technologies Group, provides a number of MSHA-approved solutions for miner safety and tracking.

One such system is PBE’s PAS-C Proximity Alert System. Using electromagnetic sensors and GPS tracking to detect vehicles, obstacles and personnel, this proximity detection device includes sensors which are worn by workers and placed on machinery and vehicles.

These sensors feed location information back to the device’s control centre, allowing operators to track their position within the mine.

The device also allows the user to configure a geo-fence zone around each vehicle in the system, helping to predict and subsequently avoid collisions. Should the geo-fence be breached, an alert is triggered, warning staff of the potential hazard.

PBE’s proximity warning systems for mines are colour-coded yellow or red based on the severity of the predicted collision, allowing staff to respond appropriately to the event.

Dash-Mounted Proximity Alert Devices for Real-Time Surveillance

A dash-mounted proximity detection device is also available through Carroll, warning drivers when they are approaching another vehicle, personnel or other obstacle. The PAS-Z Proximity Alert System provides audio and visual warnings of potential risks as well as real-time video surveillance.

The PAS-Z gives operators confidence in their movements, even when their vision may be compromised. Like the PAS-C, the PAS-Z offers geo-fencing technology, giving miners protection from pre-defined hazards such as bottlenecks and dangerous travel ways. They can be easily established using latitude and longitude coordinates.

More than 800 mines across North America trust Carroll Technologies Group for their mining safety equipment every day. Customers are able to take advantage of Carroll’s industry-leading 24/7 MinerCare team for expert assistance as well as 13 maintenance and repair centres located across nine states.
