break: To turn the block into the little floating thing that you can pick up.

destroy: To completely obliterate a block, not even leaving a little floating thing.

Given those definitions, the question is very simple. I had read about TNT mining at another question, but when I tried it, it exposed a solitary diamond. I thought this was odd because I'd never seen one block of diamond ore by itself before, which prompted this question:

Do explosions destroy stuff?

  • The TNT mining strategy is because less (not sure how much less) ore gets destroyed by TNT than normal (like it's 70% for normal blocks and it might be like 50% for ore). However there are mods that make it 0% ore get destroyed, so it's feasible with that mod. – Mr Smooth Sep 02 '11 at 04:33

Well, because I like to blow stuff up I'm not the kind of guy to be satisfied by mere Wikis, I did some experimentation:

BEFORE: enter image description here

AFTER: enter image description here

As you can see, the blast broke 9 blocks, yet I only collected 4.

So, SCIENCE(!) says that yes, explosions do destroy stuff.

Yes, they can.

Mining using TNT might be faster than mining by hand but it is impractical for gathering resources; about 70% of the blocks are completely destroyed in the process.
