Communication
Systems

  
  
MineARC’s communication systems range offers a variety of products suited to harsh industrial conditions and underground environments.
 
Designed to remain functioning when all other systems have failed, the range includes the Rescue Dog (a through-the-earth text messaging device) and Stench Gas (an odourising alert system suited to noisy locations).

  • Electric Stench Gas System

    The electric stench gas system is MineARC’s premium range, comprising a twin cylinder stench gas unit and a sub-controller that can be connected through to an existing mine control system or to the optional MineARC Stench Gas Master Controller.
     
    This fully electrical system allows for safe, remote operation of the stench gas units via the sub-controller in the event of an emergency, removing the need for local activation. – More information

    Stench gas is commonly used in underground ventilation systems as an alert gas for emergency evacuations. The powerful odour can be quickly dispersed throughout an underground mine to alert workers of impending danger.

    The MineARC Stench Gas System is designed to suit noisy locations where alarms cannot be heard. The unit will send a clear and definitive odour in the event of an emergency, indicating the initiation of emergency response procedures.

    MineARC Stench Gas cylinders carry 100g of Ethyl Mercaptan, a colourless organic liquid with a strong odour that, when added to an odourless gas, acts as a pungent warning agent. One MineARC Stench Gas Unit is effective in odourising approximately 1.25 million cubic meters of air throughout an underground mine, operating within a temperature range of 1°C to 54°C.

    MineARC Stench Gas is a non-flammable substance.

    • Easy installation and simple operation via gas release valves
    • Two 1L Stench Gas cylinders (100g Ethyl Mercaptan & R134 Propellent)
    • Independent operation of cylinders
    • Steel housing with reflective signage and viewing window
    • Pressure gauge to indicate gas levels

  • Rescue Dog System

    MineARC’s Rescue Dog Through-The-Earth (TTE) System provides critical emergency communication between surface and underground when all other systems have failed.
     
    Relying on minimal fixed infrastructure, the Rescue Dog is capable of communicating directly through the earth at distances of up to 1,500m (5000ft). A single surface controller can manage up to 16 individual sub-surface receivers, making the Rescue Dog a highly versatile and scalable communications solution for your emergency response plan (ERP). – More information

    Image
    Image

     

    MineARC’s Rescue Dog Communication System comprises a surface controller, connected to one or more sub-surface receivers deployed throughout the underground mine environment. Providing survivable two-way communication free of antennas, amplifiers or line of sight, a single surface controller can support up to 16 sub-surface receivers, each operating on its own unique channel.

    The Rescue Dog delivers TTE communication via  bidirectional beacon text messaging between underground workers and surface rescue personnel. A proprietary communication protocol allows the user to select predefined text messages, with the option to have the protocol customised to meet the specific needs of a particular site, including multiple languages.
