Blasting work in Lyttelton
Excavation of the catch bench using explosives, will start in Area C (see map) from Friday 15 June.
Explosive charges will be placed into holes drilled into the ground and detonated to break the ground apart, which will limit the noise and vibration.
It’s a very different method than the one used in March which was CATCHBENCH designed to split surface rock and released more noise and vibration.
The blasting planned for the next seven months, if you hear it, will likely sound like a couple of seconds of dull thumps in the distance. This will depend on weather conditions such as cloud and wind direction.
About three to four blasts a week will be required to remove around 100,000m3 of rock.
Please stay well away from the project area and the exclusion zone (shown in the map).
There will be warning signs and security guards at access points to prevent entry during blasting and no explosives will be stored onsite.
Contact the project team on the details below if you have any other questions or concerns.
