Nitram Draw and rdouglass, you have it wrong. The damage done is not per mine but per warhead. Each warhead in mine will hit ship separately, so it won't make any difference if you are using small mine with Warhead I or large mine with Warhead I. You will only make more hits, but won't be able to penetrate organic armor (100 mine warhead I damage vs. 150 organic armor 3) or any armor that has such resistance (like crystalline or stealth armor).

Basically in order to penetrate high resistance armor you need better warhead that makes better punch. Usually mine warhead II is enough to penetrate all armor.

Large mines have purpose in later games when large class starships come into game. When a fleet of 50 dreadnoughts enters a minefield (with restriction of 100 mines per sector) you won't be able to destroy them with 100 small mines, but large mines will do the job.
