There actually has been some serious research into using nuclear explosives as excavation tools, (including, check this out, plans to use nukes to
build a replacement for the Panama Canal! www.americanheritage.com...
However, keep in mind that even though nukes are orders of magnitude more powerful than conventional explosives, they are not the be all end all. Even
a 1 megaton warhead, which is one of the larger practical ones we can build, will only blow a hole a couple thousand feet wide and maybe 1000 or 2000
feet deep. How many are you prepared to detonate to get any decent depth?
Never mind the immense temperatures and pressures. Also, every time you hit a transition zone (crust to upper mantel, upper mantel to inner mantel,
mantel to core, outer core to inner core) you have a huge density gradient. The transition zone between the inner mantel and the outer core has a
density gradient so great as to be the equivalent of the difference between air and solid ground.
