Controlled blasts during pipeline shaft excavation
Our contractors are using some controlled blasts during excavation of the pipeline shaft in the southeast corner of the filtration facility site. The controlled blasts will be used inside the shaft to help the excavation equipment get through a layer of Boring lava deep underground.
