Segmented Refuge Chambers
In the event of an emergency (such as a fire, explosion, gas leak or roof fall), emergency refuge chambers will provide a safe, breathing-air environment for occupants. The chambers are designed to be fully autonomous for remote locations with backup batteries and back-up breathing air systems.
Segmented chambers are delivered to the mine-site in segments and assembled underground. They are attach to the mine’s main compressor air lines and electrical power sources for an indefinite supply of refuge capabilities.
A bank of fully automatic batteries at the rear of the chamber, provide back-up, emergency power, and on-board carbon dioxide scrubber with oxygen cylinders provide backup breathable air for a standard duration time of 48 hours.
Wheel and hitch packages are available to assist in moving the chambers into and around the mines and in restrictive areas.
By utilizing StrataConnect DigitalBRIDGE™, mines can cost effectively connect their refuge chambers to the mine’s communication network and open a lifeline of communication and monitoring resources.
In emergency mode, DigitalBRIDGE’s high-speed digital capabilities can provide live video streaming from onboard cameras, voice communications, personnel tracking and numerous atmospheric monitoring activities from both inside and outside shelters, including:
- Gas Levels (O2, CO2, CO, H2S)
- Door “OPEN” Sensor (optional)
- Remotely Turn Emergency Chamber Lights on during emergency
- Remotely Turn Emergency Siren on during emergency
Furthermore, daily remote monitoring safeguards the security of the shelters, and helps to ensure that they remain ready for use.
