I am in a hurry, so I'll edit this later.
A mechanical pre-hardmode... hellstone? Machine which will mine all blocks beneath it, two wide. Walls excluded. You will have a pickaxe slot and a few chain/rope slots. The chains/ropes will be consumed and lower the inserted pickaxe, mining away. It would be turned on and off with a mechanic's switch.
Recipes etc coming soon.
