The K2 Shaft Sink consisted of a blind sink vertical shaft with a 5.5m internal finished diameter to a maximum depth of 335m. The concrete lined shaft was to be split by a brattice wall (60% return air, 40% fresh air) for ventilation purposes as well as providing emergency egress (no production haulage).
