Minecraft – Fastest way to clear cobblestone blocks

minecraft-java-edition

Ok, I am a bit of an expansionist and sometimes I like to 'reclaim' land from large bodies of water. I built a wall from the bottom of the water area to the surface as a retainer wall to keep the rest of the water coming back, and filled the inside in using lava buckets… Here's my problem: is there a faster way to remove the stone/cobblestone blocks from the lava without using TNT, because if I damage the retainer wall my work will be completely undone when the surrounding ocean floods it again.

TNT can be used to safely clear solid chunks of stone and cobblestone. TNT will destroy a 5x5x5 solid block of stone or cobblestone if placed in the middle of the block. As long as you keep the TNT at least 4 blocks from the walls and you don't have any air holes, you'll be fine.

Alternatively, if you aren't adverse to using console commands, the fill command can be used to replace all blocks in a given region with another block.
