If you're being chased at the average speed of 450m/s, it means for mines to be effective, your attacker needs to be 2.25+km behind you, and have reactions about 2000% slower than the average middle aged human...

Even for unenginnered ships a trader dropping mines against a faster attacker wont have a window.
