Controlled Blasts
Regular controlled blasts occur at Snowy 2.0 worksites as part of underground drill & blast activities, as well as some above ground civil works. Exclusion zones and controls are in place to ensure the safety of all workers.
At the Snowy 2.0 Tantangara worksite, controlled blasts are carried out at the intake structure and gate shaft at the southern end of tghe reservoir. There is an exclusion zone on the western foreshore of the reservoir that extends into the marine exclusion zone. Public access will be maintained to the boat ramp and areas beyond the marine exclusion zone.
