Chamber for High Seam Mines - CoalSAFE IHS Design
The CoalSAFE International High Seam (IHS) Refuge Chamber has been designed in consultation with the world’s leading coal mining companies and regional mining authorities to best suit the underground coal mining environment. Refined over a number of years, the CoalSAFE IHS Refuge Chamber’s intrinsically safe (IS) design provides coal mining personnel with optimum safety features, functionality and performance.
The CoalSAFE International High 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.
The CoalSAFE International High Seam Refuge 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.
