IMO Mines should act as following.

Mines should have and X% chance of hitting. The percentage to be determined by game settings and perhaps components on mines.

Mines should force a fleet to stop when entering the sector.

Mines should attempet to detonate again when exiting the sector unless exiting through the same sector as the one entered.

If any ships have a sweeper component it should attempt detection of all mines. Any mines detected will not attempt detonation. The sweeper will then sweep the number of detected mines it is capable off. Any undetected mines will then attempt detonation. Any attempt on the following turn to exit the sector, other than the one entered will cause all mines to attempt detonation.
