under sea rock excavation
under sea rock excavation
(OP)
Dear all,
I'd like to find the economical method to excavate the rock under sea condition. Due to the vibration restriction, explosives cannot be used. 1.0 kine is the criteria for the vibration.
If you have any idea, let me know.

RE: under sea rock excavation
Can you use delays between blastholes to bring down the vibration?
Excavators on spudleg pontoons can dig some rock.
Cutter suction dredgers are expensive to mobilise, but can cut most rocks.
Some more information would help.
