If that is the case, I'd recommend asking an experienced person to
break the rock for you. It is quite possible to blow it up without
disturbing the cave systems or causing any noticeable noise. I have seen
a rock being blown up because a dog had been stuck under it. The dog
didn't get a scratch, but it did get a little scared ;-).

It is not necessary to use that much of an explosive.

Agreed. If the rock weighs less than a few hundred kg, this could
be the easiest way. But if you have no place to tie the rope to, then
you have to use other means. I once had to blow a stone under a shed. The
shed is still there, the rock isn't ;-).
