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.

 

 


 

The CoalSAFE Low Seam Refuge Chamber is built to the Mine Safety & Health Administration (MSHA) federal regulations ’30 CFR Refuge Alternatives for Underground Coal Mines’.

Inside a MineARC CoalSAFE Refuge Chamber, a number of vital life-support systems combine to create a safe, ongoing environment for occupants. Through innovative design, the CoalSAFE provides both a powerless carbon dioxide / carbon monoxide scrubber, as well as a powerless air conditioning system – The MARCis (MineARC Air Refuge Chamber intrinsically safe). Utilising a sequential numeric operating procedure, the chamber’s life-support systems can be activated in less than 60 seconds.

CHAMBER EXTERIOR – FRONT

Lifting Lugs

Lifting lugs on all four corners of the chamber.

Porthole Window

12mm porthole viewing window, compliant with Australian Standard 2208. Blast shield protection available upon request.

Reflective Signage

Safety and operational signage in reflective stickering for high visibility underground. Translation into a second language available.

Sealing Door

Outward opening door, featuring double locking rotating handles. The vacuum tested seal maintains a positive internal pressure.

Skid Base

The skid base provides ease of mavoeuvrability, featuring 250 x 100mm forklift slots, front and rear mounted tow points and front mounted 25mm steel plate push blocks.

Paint

High durability white paint for underground visibility. Sand blasted to 2.5 grit, and in compliance with AS/NZS 2312:2002.

Steel Plate Construction

Explosion resistant steel plate with external support wraps and surround package, built to withstand in excess of 15psi (103kPa) overpressure.

 

 

CHAMBER INTERIOR

Seating

MineARC seating is ergonomically designed to provide suitable comfort during entrapment. Made from durable, hard wearing fabric, the seating provides 500mm of space per person.

MARCISORB Chemical Cartridges

MineARC’s MARCISORB CO2 and MARCISORB CO cartridges provide superior scrubbing capacity, are easy to load, safe to handle, and can store for long periods.

MARCis Scrubber System

The MARCis (Intrinsically Safe) scrubbing system does not require electrical power to operate. The system scrubs the air of CO and CO2 build up.

Air Conditioning

Intrinsically safe system. Air conditioning is vital to combat the potentially fatal effects of heat stress, caused by the occupant’s metabolic activity, as well as any ambient heat .

Operating Procedures

Operating procedures are located on the wall of the refuge chamber, as well as within hardcopy manuals. Operating procedures can be translated into a second language.

Flooring (Not Pictured)

Non slip, removable flooring is featured throughout the refuge chamber.

Skid Base

The skid base provides ease of mavoeuvrability, featuring 250 x 100mm forklift slots, front and rear mounted tow points and front mounted 25mm steel plate push blocks.

Lifting Lugs

Lifting lugs on all four corners of the chamber.

Steel Construction

Explosion resistant steel plate with external support wraps and surround package, built to withstand in excess of 15psi (103kPa) overpressure.

  • 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 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

  • CoalSAFE Change-Over Station

     
     
    The MineARC CoalSAFE Change-Over-Station (COS) is designed to aid underground personnel as they exit the coal mine during an emergency. The station provides a secure ‘staging-post’ stocked with replacement breathing apparatus.
     
    Inside the COS, breathing apparatus such as self-contained-selfrescuers (SCSR’s) can be changed over in safety while providing personnel the opportunity to regroup and continue to plan their escape. Each model features custom-designed storage to accommodate site requirements. – More information
