Depends on a lot of things.  I've used measured amounts of dynamite 
within 5 feet of a building foundation.  Didn't break any windows and 
didn't crack the foundation.  This was in very heavy and almost rigid 
clay, digging a hole for a fuel tank for their oil fired furnace.  A lot 
of quarter sticks sure speeded it up.

I will also add that this was a long time ago.
