Now with enough mental gymnastics you might be able to rationalize effective minefields around "choke points" like warp points or planets, but in interplanetary space, forget it.

Assuming they're like terrestrial mines. Given that they have IFF, I doubt they are.

What a lot of SF does is make "mines" basiclly missile warheads attached to senstive passive sensors and a short-burn missile engine. They detect a ship, wait until its at its closest point, and then intercept it.
