  • MineSAFE Permanent Refuge Shelter

    Changing the Safety Landscape across Africa: Mopani Copper Mine

    Mine safety is a global concern, with organisations continually investing time and resources to ensure the safety of their workforce. A critical step to achieve this is improving emergency response procedures through using better technology and increasing skilled workforce. – More information

  • GuardIAN Remote Monitoring & Diagnostics

    MineARC’s GuardIAN Remote Monitoring and Diagnostics System is an exciting new development in refuge chamber technology. GuardIAN enables real-time monitoring; providing confidence that an operation’s fleet of refuge chambers are emergency ready at all times.
     
    GuardIAN is an independent system that continuously monitors all vital refuge operating systems. During standby mode GuardIAN checks for component faults and monitors refuge chamber usage or entry to the chamber.
     
    GuardIAN is available as an option on any new MineARC Refuge Chamber or Safe Haven, and also to retrofit to existing chambers during an upgrade or refurbishment.

  • Aura-FX Digital Fixed Gas Monitoring

    Gas monitoring is an essential aspect of maintaining a life supporting atmosphere within the refuge chamber. During entrapment, occupants
    consume oxygen and expire carbon dioxide (CO2) and carbon monoxide (CO) as part of their normal respiration. CO can also enter the chamber during occupant entry and if the compressed air intake is compromised.
     
    Closely monitoring gas levels in the chamber allows occupants to take corrective actions to maintaining a safe and inhabitable environment.
    MineARC’s new Aura-FX Digital Gas Monitoring System is a proprietary fixed gas monitoring unit, designed specifically for use in refuge chambers and safe havens.
     
    Aura-FX is standard on all new MineARC Refuge Chambers and Safe Havens. It is also available to retrofit to most existing chambers during an upgrade or refurbishment.

  • Airlocks & Vestibules

    MineARC airlocks and vestibules are designed to act as a staging area between the enclosed protection of the chamber and the outside environment.
     
    They feature positive pressure flushing systems that ensure the out-flow of air; preventing the ingress of contaminants while the door is open for entry. The Positive Pressure Flushing System (PPFS) provides high speed pressurisation and is activated via a simple electric push-button system.
     
    MineARC offers a range of internal and external vestibule solutions designed to suit a wide variety of applications and entry requirements.

  • Compressed AirManagement System

     
    The Compressed Air Management System (CAMS) is a breathable air system that is unique to the market; offering a range of features aimed at reducing running costs and improving operational safety during an emergency.
     
    Aside from providing clean breathable air through a superior four-phase filtration process, some of the major benefits of CAMS include; optimisation of mine air services, guarantee against over pressurisation of the refuge chamber, gas toxicity monitoring, flood protection, and reduced service time during filter change-out.
     
    Currently owned chambers can be upgraded with the CAMS upon request. – More information

  • Series IV Scrubbing System

     
    The MineARC Series IV Electrical Scrubbing System is considered to be the most advanced safe refuge technology in the world. The Series IV boasts all of the improvements of the Series III system, plus a host of additional features including a superior digital control system and intelligent voice audio navigation (i.V.A.N).
     
    Additional improvements include pre-packaged MARCISORB Chemical Cartridges, intuitive operation, motion sensor logging and a modular controller design. – More information

  • ELVP / ELV Scrubbing System

     
    MineARC’s unique ELVP/ELV (extra-low-voltage) Scrubbing System works in conjunction with active chemicals to ‘scrub’ the build-up of harmful CO2 and CO from the air inside the refuge chamber.
     
    The ELVP/ELV represents six years of technological advancements to the original PLP (powerless portable) scrubbing system, in a safer, more reliable design.

  • Series IV Scrubber

    The MineARC Series IV Scrubber is the “Control Unit” of an expandable scrubbing system that is capable of providing CO and CO2 scrubbing while also providing cooling/heating to large scale sealed environments.
     
    The Series IV scrubber utilises the same technology found in MineARC’s MineSAFE portable refuge chambers and is capable of providing remote monitoring (optional), self-diagnostics, 4-20mA monitoring, and voice prompt operating instructions (iVAN). – More information

  • MineSAFE Permanent Shelter

     
     
    A permanent refuge chamber (as opposed to portable) can often prove to be a more efficient and cost effective solution for an underground mine. In particular, mines that;
             
    • Have a large number of personnel underground at any one time,
    • Have low excavation costs, and
    • Where the regular movement of personnel underground remains within certain areas.
             
    Permanent refuge chambers therefore often double as break, rest and lunch areas, capable of sheltering upwards of hundreds of personnel at any one time. – More information

  • Air Conditioning

     
     
    All MineSAFE Permanent Chambers include quality reverse cycle split-system Mitsubishi Air Conditioners to both cool and dehumidify the refuge chamber. The evaporator unit is located inside the refuge chamber, and can be mounted to the Series IV
    Scrubbing System or remotely.
     
    Meanwhile the condenser fan is positioned outside the refuge chamber, mounted on top of the battery backup UPS or remotely. – More information

  • UPSBattery Backup

     
    A secure steel cabinet outside the main refuge chamber houses the refuge chamber’s battery backup UPS (Uninterruptible Power Supply). The UPS is a fail safe system that can power the refuge chamber’s internal life support systems for a minimum of 36 hours should mains ‘mine’ power become cut-off.
     
    Cooling capacity is the major determining factors behind the size of the UPS required for a specific refuge chamber. Refuge chamber volume, ambient mine temperature and intended occupancy will all contribute towards the size of the air conditioner, and subsequently the battery backup system necessary.

  • Compressed OxygenCylinder Racks

     
     
    If mine air supply fails, refuge chambers should be fitted with a reliable secondary source of oxygen supply (O2). MineARC Scrubbers operate in conjunction with breathing grade O2 cylinders.
     
    All scrubbers are supplied with a primary and backup oxygen regulator as well as Latex Gloves for handling.

  • BulkheadDoors

     
     
    MineARC manufactures a range of bulkhead doors to suit project specifications. All doors are constructed from solid steel plate, with double-locking rotating handles, rubber seals, portal windows, and check valves to ensure a fully sealed environment.
     
    Doors can be configured either with a bulkhead mounting frame (allowing walls to be built around the door), or without a mounting frame, should a door cavity already exist.

  • FlushingAirlocks

     
     
    MineARC offers a fully inclusive airlock or alternatively flushing racks for inclusion in pre-existing airlocks. Both systems provide high speed flushing and are activated via a simple pneumatic push-button system.
     
    The fully-flushing airlock can optionally use compressed ‘mine’ air as the primary source of air for flushing. If mine air is lost or becomes contaminated, high pressure compressed air cylinders provide a backup supply for flushing.
