CoalSAFE MSHA Low Seam Refuge Chamber
The CoalSAFE MSHA Low Seam Refuge Chamber is designed for underground coal mines with a minimum seam height of 46” (1.2m). The refuge chamber can be custom designed to client specifications, but typically features 12, 16, 20 and 24 person configurations.
The CoalSAFE Low Seam Refuge Chamber is approved in the United States by the West Virginia Office of Miners' Health, Safety & Training and built to the Mine Safety & Health Administration (MSHA) Federal Regulations '30 CFR Refuge Alternatives for Underground Coal Mines'.
The CoalSAFE MSHA Low Seam Refuge Chamber features an innovative, intrinsically safe life-support system that is unique to MineARC Systems; providing both powerless CO/CO2 scrubbing and airconditioning. Utilising a sequential operating procedure, the intrinsically safe system can be activated in less than 60 seconds during a coal mining emergency.
Due to the height restrictions of low seam operations, the CoalSAFE MSHA Low Seam Refuge Chamber features a secure, separately transportable External Cylinder Bay (ECB) to house the oxygen and liquid CO2 cylinders required to power the refuge’s internal life support systems.
