just a crazy random idea.
Single use miner:
no need to place tool/scaner/pipes inside
no need to set up power grid. just power it once before use or fuel (single use battery) powered (included in recipe)
can't go further than 70 blocks
can't deal with water/lava
can mine only metals. can't mine diamonds/lazuli/redstone/gems/etc (because of cheap magnetic scanner maybe)
makes no sense to use with mods like COG due to low yield
