FABs provide an operational stronghold for emergency response teams to coordinate rescue efforts underground – acting as a pivotal point for communications, planning and a safe location …
Refuge Chambers (also known as Refuge Stations) form an integral part of an underground hard rock mine's wider Emergency Response Plan (ERP). Fires, explosions, rock-falls, flooding and the release of smoke and other forms of toxic gas are the types of incidents that occur all too frequently, despite the high levels of planning and the safety …
The refuge chamber provides a safe space where people can stay safe when they are trapped by an accident in a coal mine. The refuge chamber includes several systems such as oxygen supply, air purification, cooling, and dehumidifying. The oxygen supply system is the core of the refuge chamber because it is a closed environment. …
