MineARC CoalSAFE

In consultation with the world’s leading mining companies and regional mining authorities, MineARC Systems has designed and engineered a range of intrinsically safe CoalSAFE models to suit different underground mining environments. Refined over a number of years, the MineARC CoalSAFE Refuge Chamber provides miners with optimum safety features, functionality and performance.
  
Configurations range from 8 to 24 person occupancies.
   
Ultimately CoalSAFE Chamber dimensions and rated occupancy can be custom-engineered to site specifications, without compromising on safety or performance.

 

CoalSAFE Change-Over Station Series

 

The CoalSAFE Change-Over-Station is constructed from 5mm steel plate, with internal support wraps and surround package as standard. The intrinsically safe design features both a positive pressure entry and independent breathable air supply (high pressure compressed air cylinders), stored within the robust steel structure. After entering the main chamber area, miners may require a rest break or some time to wait for others and re-group before donning there SCSR’s and moving onto the next COS. In this instance, miners can activate the positive pressure system inside the main chamber.

 

The floor of the COS is manufactured from 6mm steel plate with tubular skids. Push points are provided top and bottom at both the front and rear of the unit, providing easy manoeuvrability within an enclosed space.

 

Other internal features include durable, ergonomically designed seating, dedicated storage areas for housing SCSR’s, and a communications port.

  • CoalSAFE International High Seam

     
     
    The CoalSAFE International High Seam Refuge Chamber is designed to suit a range of underground coal mining environments. The chamber can be custom designed to client specifications, but typically features 12, 16 and 20 person configurations.
     
    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. – More information

  • CoalSAFE MSHA Low Seam

     
     
    The CoalSAFE MSHA Low Seam is designed for underground coal mines with a minimum seam height of 46” (1.2m). The chamber can be custom designed to client specifications, but typically features 12, 16, 20 and 24 person configurations.
     
    Due to the height restrictions of low seam operations, the CoalSAFE Low Seam features a secure, separately transportable external cylinder bay (ECB) to house the oxygen and liquid CO2 cylinders required to power the refuge’s intrinsically safe internal life support systems. – More information

  • CoalSAFE MSHA Mid Seam

     
     
    The CoalSAFE MSHA Mid Seam is designed for underground coal mines with a minimum seam height of 56” (1.4m).
     
    The unit can be custom-engineered to client specifications, but typically features 8, 12, 16 and 20 person configurations. – More information

  • CoalSAFE MSHA High Seam

     
     
    The High Seam CoalSAFE model is designed for underground coal mines with a minimum seam height of 74” (2.2m).
     
    The unit can be custom-designed to client specifications, but typically features 12, 16, 20 and 24 person configurations. – More information
