Oh i'm not even using it on my own save since it'll wreck the balance to a comical degree, another mod of mine (which i also do not happen to use myself) might be a more balanced way to balance core miners: https://mods.factorio.com/mod/se-core-miner-drilling-mud
Note that the 10gw power is only for active drills, if you cannot keep up the power will be managable, likely. :)
Im tempted to make a addod that adds one Big drill that consumes lubricant and iridium drills (they can be reused with some maintanance) to mine entire planet worth of core miners or have another recipy that will use Crio fluid to mine them with 80% of efficency on all drills.
All I need i knowledge of Lua, 3d modeling and factorio modding. If I only I get to it some day xD.
