Hard rock mining involves uncovering and extracting non-fuel metal and mineral deposits of solid ores or eroded deposits in stream beds. Permanent Refuge Chambers can be used for secondary purposes such as refectory, first aid room and meeting point for the personnel. This system stands out as the most economical solution for large number of personnel underground at any one time. Permanent Refuge Chambers are created by sealing a concrete room that is formed in the mine. The chambers are required to be located in close proximity to worker areas. Communication equipment is also available. The capacity and duration can vary depending on the chamber build. The sealed area has a closed circuit breathing apparatus where carbon dioxide and other toxins are removed, oxygen is added, and temperature and humidity are maintained, all while protecting occupants from the external threat. Refuge chambers need to be sealed to prevent the ingress of toxins such as smoke contaminating the breathable air within the chamber. They provide a secure area with shelter, water, and breathable air, for people to remain until they are rescued or the hazard subsides. In emergencies, when evacuation is no-longer safe or practical, the rescue chamber is designed to provide a safe and secure ‘go-to’ area for personnel to gather and await extraction.Įssentially, rescue chambers are sealed environments built to sustain life in an emergency or hazardous event such as a truck fire or toxic gas release. Refuge chambers come in multiple types and models, and are used in multiple industries including metalliferous mining, coal, tunnelling and petrochemical facilities. It is also known as refuge chamber, refuge bay, or refuge alternative.
