& Upgrades

Virtually all aspects of a MineARC Refuge Chamber or Safe Haven design can be customised by our in-house team of engineers, including; dimensions, structural integrity, volume, occupancy and minimum entrapment duration.
MineARC offers a range of options and upgrades based on industry and application.

With simple “plug and play” installation, set up and connectivity of GuardIAN is fast and easy. All diagnostics and real-time monitoring are easily accessible through a secure, locally hosted webpage; compatible with any computer, tablet or smart phone. The GuardIAN online interface home page features a summary of your entire refuge chamber fleet and overall operational status, with the ability to drill down to a detailed report of each chamber.

When utilised as part of the full System Intelligence network, GuardIAN can provide a range of additional diagnostic features. For Refuge Chambers with a MineARC Compressed Air Management System (CAMS), the GuardIAN dashboard will provide vital information relating to the integrity of the internal refuge chamber atmosphere. An increase in CAMS activity would indicate a breach of the refuge chamber seal, thus sending an alert to designated personnel that there is a problem.

When utililsed in conjunection with MineARC’s Aura-FX Digital Gas Monitoring System, GuardIAN will also provide real-time gas monitoring data and analysis. For more information regarding MineARC System Intelligence, visit minearc.com/systemintelligence.

Live video streaming can greatly assist in evacuation planning during an emergency; providing the capability to determine the capacity of the refuge chamber and monitor the well-being of occupants. It is also useful in monitoring unauthorised usage of the refuge chamber, or on sites where theft is an issue.

Internal video monitoring is provided by a remote controlled, motion activated GuardIAN IP camera. External video monitoring is also available as an optional upgrade to the GuardIAN System.

Motion detectors on the IP cameras will notify GuardIAN to send out an email notice to designated staff with a still image alerting them to chamber usage. When activated, the cameras will send out a live, recorded stream of both the interior and exterior of the refuge chamber.




To assist occupants during an emergency or safety drill, GuardIAN also equips your refuge chamber with a VOIP video phone. This facilitates face-to-face communication between the refuge chamber and the surface; improving the psychological well-being of chamber occupants during an emergency and providing assistance to perform any difficult or technical procedures.

An added benefit of VOIP video phone access is that underground service and maintenance staff can make contact with technicians on the surface or even to be connected through to the MineARC Service Team for trouble shooting assistance.




MineARC’s Series IV Digital Control System links directly to GuardIAN, streaming real-time system data to a surface control room. Data includes automated system checks, fault logging (battery, scrubber, temperature and inverter), system diagnostics, internal and external temperature measurements, and system actions such as scrubber activation.

System faults, events and scheduled service notifications can be sent to designated personnel as email alerts; notifying them of upcoming service requirements, potential emergencies or system errors as they occur.




GuardIAN’s secure online interface is hosted on an internal server within the refuge chamber so that no software installation is required. This interface enables the user to monitor their full chamber network status on one simple menu screen, and then drill down further to detailed activity reports, fault logs and system diagnostics for each individual refuge chamber.

The responsive web interface is easily accessible from any computer, tablet or smartphone. Extra features like live video monitoring and event push notification are available through all devices including smart phones and tablets.




  • 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.

  • Blast Rating Upgrade

    An optional feature for all MineARC Refuge Chambers and Safe Havens is a blast rating upgrade.
    MineARC utilises highly specialised materials and engineering techniques to build chambers that can withstand the concussive forces of extreme blasts and explosions within heavy industry. Through careful analysis of a site’s application and hazard assessment, MineARC can engineer a highly customised refuge chamber or safe haven to meet their specific blast rating requirements.
