Pre-Built Refuge Bay Solution
– MineSAFE Portable Permanent
The MineSAFE Portable Permanent offers sites a built-in refuge option for up to 100 personnel that can be easily installed where needed. Later, as a mine is developed, the refuge chamber can be removed and relocated to where shelter is required most.
All componentry for safe refuge is housed within a standard framework of recommended equipment, vital to safe operation of the shelter in an underground emergency.
Once positioned at the entrance of a dedicated refuge bay, the MineSAFE Portable Permanent is built into to a bulkhead wall and then sealed. Drone scrubbers, booster fans and chairs are positioned within the refuge bay; then the refuge chamber simply needs to be connected to power and compressed air to be fully functioning. This eliminates the need for an intensive installation process.
MineSAFE Portable Permanent componentry can be scaled to provide safe refuge for 25 to 100 people. The allocated refuge can also double as break, rest and lunch areas during normal operation.

Why are scrubbing systems required?
Carbon dioxide (CO2) and carbon monoxide (CO) are expired by refuge shelter occupants as part of their normal breathing activity. Carbon monoxide can also enter the shelter via the compressed air intake if it becomes compromised, and as occupants enter and exit the refuge chamber. In high enough concentrations, carbon dioxide and carbon monoxide poisoning can lead to a loss of consciousness and eventually, death. Carbon dioxide and carbon monoxide removal is therefore a vital necessity for any refuge shelter.
Series IV Scrubber
The MineARC Series IV Scrubber is the “Control Unit” of an expandable refuge shelter scrubbing system, that is capable of providing CO and CO2 removal while also providing cooling and heating to large-scale sealed environments. The Series IV scrubber utilises the same technology found in MineARC’s MineSAFE Standard Design Refuge Chamber and is capable of providing remote monitoring via GuardIAN (optional), self-diagnostics, 4-20mA monitoring, and voice prompt operating instructions with i.V.A.N.
Compressed Air Filtration System (CAFS)
Compressed Air Filtration Systems are fixed to a refuge chamber to remove traces of contaminants such as water, carbon dioxide, carbon monoxide and other toxins. Most are equipped with a three or four-stage filtration process that allows safely filtered mine air to pass into the main refuge bay.
- Water Separation: Prevents large amounts of water entering the chamber.
- Preliminary Filter: Removes larger particles.
- Coalescing Filter: Removes finer particles of water or oil.
- Absorbent Filter: Removes diesel particulate, odours, volatile organic compounds, small levels of carbon monoxide and very fine oil particles.
Optional – Airlock Activation
The MineSAFE Portable Permanent Refuge Chamber features a two-door entry way (passive airlock) as standard. Clients may select from a range of activation options for the airlock.
An airlock is designed to act as a secure staging area between the safety of the permanent refuge shelter and the outside environment, significantly reducing the threat of contaminants being brought into the refuge bay on entry during an underground mine emergency.
MineARC offers a choice of a normal entry or high flow entry airlock, with a number of optional add-ons to further improve the flushing efficiency during personnel entry.
