Shaft excavation will begin at the Suomenlahdentie shaft at the West Metro Finnoo worksite in week 47, from 20 November. Excavation will mainly involve tunnel excavation, as the shaft will be excavated upwards from the tunnel to the ground level. The last blasting at the ground level will involve open excavation.
The blasting work will last about three weeks, followed by reinforcement work and making of the concrete structures. All in all, work on the shaft is expected to be completed in March 2018.
The tunnel excavation will be performed from Monday to Friday between 7 am and 10 pm. The last blasting operation, to be performed as an open excavation, will comply with the working hours specified for open excavation (Mon-Fri 7 am to 6 pm).
