SA’s mining industry is heading for the deadliest year since 2012 after six people died in an underground fire at Palabora Mining copper operation.

Our revolutionary technology can minimize a tragedy like this happening again!

DRUM® Compact Portable (CP) Radio

The DRUM® CP Medium Frequency Radio is a battery powered, digitally controlled, analog frequency modulation, single-channel voice communication radio. It uses a two-element omnidirectional magnetic induction antenna operating in the medium frequency (MF) band to propagate its signal parasitically across metal infrastructure in an underground / tunnel environment.

Under normal operating conditions, signals can be relied on to propagate many miles between the sending radio and any receiving radios with little attenuation. In post-incident emergency circumstances, when conductive infrastructure has been altered or damaged, the units can be moved to propagate their signals on surviving conductive infrastructure, forming a survivable redundant communication path.

The DRUM® CP is compatible with the DRUM® Repeater Units, in that it can send and receive voice transmissions interchangeably with the DRUM® Repeater’s MF interface. The product is lightweight, rugged, and man-portable.

DRUM® CP – Features

  • Lowest Cost-Per-Foot of Any Communication System on the Market – By Far
  • Fulfills the MINER Act Requirement for a Redundant Communication System
  • Seamlessly Interoperates with Existing UHF / VHF Leaky Feeders and Handsets
  • Supports Point-to-Point Voice Range of Over 5 Miles Underground
  • Communication in hard to reach spots, temporary working areas, and bleeders

DRUM® 100R – Medium Frequency Repeater

The DRUM® 100R Analog Repeater is a dual-band radio, where one of the front ends operates at medium frequency and the other front end operates at either VHF or UHF. The analog repeater continually listens to both frequencies. When one of the front ends detects an incoming signal, the analog repeater shifts the signal and retransmits it on the other front end. Tone squelch is used to indicate the presence of a valid signal.

Under normal operating conditions, signals can be relied on to propagate many miles between the sending radio and any receiving radios with little attenuation. In post-incident emergency circumstances, when conductive infrastructure has been altered or damaged, the units can be moved to propagate their signals on surviving conductive infrastructure, forming a survivable redundant communication path.

DRUM® 100R – Features

  • Installs in Hours – Complete Install in Less than One Day
  • Extends the Range of Leaky Feeder with No Extra Wires or Cables
  • Voice Data from VHF or UHF Handhelds will be Transmitted onto the Leaky Feeder
  • Trolley Phone Replacement

WIRELESS ALERT REMOTE NOTIFICATION

The mining environment underground is extremely volatile and miners are exposed to many dangers such as Rock falls, toxic gases, explosions and fires. Communication underground is unfortunately unreliable and due to this communication only really exists in the developed areas of the mine. The miners that are blasting and digging in the undeveloped areas are fully dependent on communication from the shift manager or the likes regarding any danger warnings from surface.

The WARN is a device that will be assigned to each individual miner and will alert them immediately of any danger known to surface. The WARN receives an emergency medium frequency signal sent from a transmitter on surface which is sent by magnetic induction. This means that the signal is sent through the existing metallic infrastructure underground and is not dependent on any communication cabling. The WARN device can give audible, visual and vibration warnings insuring the miner has every chance of early notification of imminent danger and has the chance to make it to a refuge bay as quick as possible.

The WARN device empowers each miner and removes the dependency of others warning them of danger and allows for the earliest possible warning leading to the quickest possible reaction ultimately saving lives!
