Overview

Note, this event is both online and in person. The online registration link will be coming soon. 

Join us for an insightful technical presentation showcasing a compelling case study on the excavation of Tailrace 1 at the Kidston Pumped Storage Hydro project. This innovative approach involved excavating from the inside out, without prior access to the external portal face. The presentation will detail the unique methodologies employed, including the implementation of ground support systems and specialized techniques for achieving a bespoke breakthrough. Gain valuable insights into how the final breakthrough blast was carefully executed and supported to ensure structural stability upon completion.
