Booyco Electronics reported its proximity detection system (PDS) helps South African miners comply with the Level 9 safety standards. The standards require full intervention from a PDS on trackless mining machines to prevent machine-to-man incidents.

Booyco’s PDS uses VLF antennae on a vehicle to create fields within a danger zone around the vehicle. The size of each field can be determined by the customer. An RFID tag installed on the pedestrian’s cap lamp alerts them with a light and an alarm when they enter this zone. The light changes color, from green to orange and then red, the closer the pedestrian is to the vehicle. The vehicle itself also receives a warning from the PDS. When so configured, the vehicle can also be automatically slowed down or stopped.

The system can detect as many as seven machines and 20 pedestrians within one field in the underground environment, the company reported.
