Abstract:
For deep hard rock shafts a new shaft boring system has been developed by Herrenknecht AG in collaboration with Rio Tinto. Based on proven technologies the system utilises a unique arrangement of existing proven technologies. The system integrates excavation, mucking, primary rock support, installation of the final lining, and shaft infrastructure. This new system dramatically improves the health and safety of shaft construction. Detailed performance estimates indicate significantly higher shaft construction rates are possible compared to conventional shaft sinking methods.
