Becker Mining’s turnkey proximity detection systems

November 2017 IS & Ex

Becker Mining South Africa provides turnkey proximity detection systems (PDS), as well as tagging and tracking and related communication systems, which comply with stringent mining health and safety regulations.

The company has developed advanced proximity detection systems for nearly 20 years, which have significantly improved safety on the mines. Becker’s modular PDS solutions are designed to prevent potential collisions during the operation of vehicles in the proximity of personnel on the surface, or underground.

“The company’s latest patented tri-technology PDS solutions – which range from a simple, low-cost single technology system, to integrated multi-technological solutions – encompass all aspects of the most advanced mining communications and technology,” states Andrew Trentelman, senior general manager electronics, Becker Mining South Africa. “Becker’s patented tri-technology point of detection system is the only system available globally that combines three technologies, UHF, radar and electromagnetic, into one scalable system.”

Bidirectional notification and early warning messaging alerts vehicle operators and personnel to the presence of each other, and to stationary or moving vehicles in close proximity, thus enhancing safety in arduous underground conditions.

Becker’s latest PDS controller, which is the interface between the vehicle operator and multiple detection sensors mounted around the vehicle, provides various alert mechanisms for operators. These include cabin lighting and alert tones that are selected to suit exact requirements.

The system comprises customisable caution, warning and critical zones. Detection zone threshold distances are set according to specific requirements, covering small and large vehicles.

Tri-technology guarantees reliable communications

Becker’s advanced solutions prevent electromagnetic interference, by transmitting data packets across the generated H field. Data received is recognised as a system tag and not an environmentally generated signal that could cause unnecessary warnings.

The tri-technology tag, which supports accident investigation and multi-mode operation, is compatible with Becker’s tagging systems and communications networks. This tri-axis electromagnetic receiver ensures reliable detection by the system, regardless of the tag or miner’s position.

Vehicle tags are self-powered RF devices that ensure the presence of a vehicle continues to be broadcast, even if the ignition has been turned off or the battery has been isolated. Control tags transmit specific commands to PDS controllers and miner tags, also providing alerts when entering a restricted or hazardous area.

Advanced self­diagnostic functionality provides continuous monitoring of all peripherals connected to the system, to ensure equipment is functioning correctly. The operator is immediately warned if a device stops responding to the PDS controller.

Becker Mining’s high performance, fit for purpose solutions for underground and surface mining installations, include Leaky Feeder, Wi-Fi, tagging and tracking, as well as environmental monitoring PDS solutions.

In addition to communications solutions, Becker also offers IS and flameproof underground electrical reticulation products, as well as fluid transfer, rigging and rope attachment systems. An important feature of these systems is that they are designed to facilitate future upgrades.
