DescriptionThe drill steels from underground are taken up from underground in special carry wagons to the tool sharpening workshop within the Man and Supply area where they are reshaped and sharpened. The drill steels are hollow for water to be injected into the holes for cooling and flushing the chippings out as well as dust suspression. This appears to be an internal shaft.RightsPublic DomainCollectionReginald O'BrienSubjectMiningMining Sites
