Emergency refuge forms an integral part of an underground mine’s wider Emergency Response Plan (ERP). Fires, explosions, rock-falls, flooding and the release of smoke and other forms of toxic gas are the types of incidents that occur all too frequently, despite the high levels of planning and the safety precautions in place. In these types of emergencies, when evacuation is no-longer safe or practical, emergency refuge is designed to provide a safe and secure ‘go-to’ area for personnel to gather and await extraction.
 
  
Helping safeguard miners in over 40 countries, across six continents, the MineARC MineSAFE series is the world’s most trusted refuge chamber in metal (hard rock) and non-metal mines.

 

MineSAFE SD Series

 

 


 

Inside a MineSAFE Standard Design Refuge Chamber, a number of vital life-support systems combine to create a safe, ongoing environment for occupants. The chamber features a MineARC Series IV Controller; the most advanced safe-refuge technology anywhere in the world.

Ultimately an SD refuge chamber’s dimensions and its rated occupancy can be custom-engineered to site specifications, without compromising on safety or performance.

Special transport configurations include narrow builds specifically tailored for shaft mines, or modular builds, allowing a complete refuge chamber to be split into smaller sections before being transported and then reassembled underground.

  • MineSAFE Narrow Design

    The MineSAFE Narrow Design (ND) features a slimmer shell, designed specifically to accommodate tight hard rock mining confines such as shaft mines, while still providing ample internal space for a range of occupancies – from 8 to 26 people.
     
    The chamber’s portable design makes it easy to manoeuvre and position around site. – More information

  • MineSAFE Compact Design

    The MineSAFE Compact Design (CD) is designed specifically for tight mining confines, such as single-entry development headings. This small, compact, ultra-portable refuge chamber is easy to manoeuvre and position around site.
     
    The Compact Design is designed for optimum autonomy. The chamber’s ‘extra-low-voltage’ control system means it can sit stand-alone for extended periods without requiring connection to mains (mine) power (around 6 weeks). – 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
