The problem with AP mines is that nobody's successfully found and exploited a "hardwired" method of detection.
Each mapfact mine has a separate script does a nearestobject scan on a spot 2 meters above the mine. If that object is not the mine, and that object is moving, it detonates.
It scans 1000 times a second or so.
The best way to make mines like that work is to use them on desert island in small numbers, with no other scripts. So far nobody has succeeded in making AP mines that can be deployed in large numbers.
