Becker Mining SA Launches Technologically Advanced Smartcom VHF Leaky Feeder System

Becker Mining SA – specialists in safety, energy distribution and communication solutions for the mining sector, have upgraded underground communication technologies by launching a more advanced Smartcom VHF leaky feeder system. 

This new product is engineered for dependable performance in harsh mining environments.

“Designed to deliver multiple simultaneous voice and data radio channels with minimal intermodulation noise, the Smartcom system has become a critical component in mining operations, where safety and continuous communication are paramount,” says Rick Jacobs, Senior General Manager: Mechanical, Becker Mining SA. 

“Mines are usually remote from major cities and established infrastructure, which makes access to communication specialists and services difficult for the mining sector. The robust Smartcom VHF leaky feeder system, which has been installed in mines globally and throughout the African continent, is known for dependable performance and requires little maintenance.”

Reliable and clear communication systems are essential in the mining sector due to hazardous underground conditions. This highlights the need for technologically advanced feeder systems that ensure reliability, flexibility, and low maintenance requirements. Such systems enhance safety in this challenging industry.

“We understand that one standard system does not meet the specifications of every installation, which is why we design our leaky feeder systems to suit exact mine sizes, requirements and budget constraints. The Smartcom VHF system’s modular design allows easy tailoring to site-specific requirements and budgets. Amplifiers are available with both manual and automatic gain control, as well as local or remote diagnostic functionality.

“The forward-pilot-based automatic gain mode eliminates the need for a return pilot signal, significantly reducing system noise and the likelihood of communication failures, especially in the event of cable damage or pilot loss. This intelligent gain adjustment improves reliability and reduces operational overheads.

Smartcom VHF leaky feeders are engineered with an upgrade path that allows for a range of installations, from basic to advanced configurations utilising various trunking technologies. The system can support multiple voice and data channels over long distances. High RF gain amplifiers enable wider spacing, typically up to 500 meters, between units, which helps to minimise the number of components needed and reduce installation costs.

To enhance safety underground, a missing-person location system can be integrated via two-way radio, Bluetooth, LTE and Wi-Fi systems. Integration with SCADA and HMI systems further extends functionality into process control and automation, enabling remote control of ventilation fans, pump motors and cavitation systems.

Remote diagnostics are a key feature of the system’s advanced design. Becker’s RNG-AMP and BSC-AMP amplifiers can transmit vital system data, such as DC line voltage, downstream RF power, and gain control settings, via a web interface to surface-based operators. This capability simplifies fault identification and reduces downtime by enabling technicians to locate and diagnose issues before physically entering the mine.

The system’s in-line data capabilities, which form part of the upgrade path, include a 150 In-Line Data Module (UIDM) that connects to the leaky feeder network. This module ensures low mainline loss and provides a serial connection to an onboard serial (UART) device. The connected serial device is powered through the IDM, and one external antenna port is provided for tag reader functionality. The Smartcom 150 UIDM works in conjunction with the Surface Data Module VSDM-150WW# to provide an Ethernet connection at the head end.

The availability of upgrade kits allows Smartcom installations to accommodate changing operational demands. These kits can be deployed on site without the need to return equipment for modification. Optional telemetry and tag reader modules can be added, offering extended capabilities such as resource tracking and environmental monitoring.
