Hi!
What is the right damage criteria for buildings placed on hard rock. I know the standars say about 70 mm/s, but does anyone have knowlegde and experience around this?
I would like to get as much data as poosible from projects where vibration damage are caused by blasting in hard rock areas. Data like spesific charge, distanse, type of rock, type of damage in buildings etc.
Thanks a lot!

Hi,
I donn't know what's kind of standards you mentioned. 70mm/s is too high. In my memory, it is about 20mm/s for building.
