You can manually target with Mines: during this 1.5 seconds interval, manually selecting another target in the radius of the Mine will reset the time bomb and thus the aforementioned protocol (1.5 seconds delay → is the target still in range? if yes, shoot; if no, auto-acquire another target if there is one available). If, for some reason, you need to hold fire with a Mine, you can keep switching targets and prevent the Mine from shooting until you're ready.
Mines have 5 range, but can sometimes trigger against 6-ranged targets (such as Stalkers, Marauders or Hydralisks with the range upgrade) attacking them because instead of stopping at exactly 6 range, it seems units sometimes do not decelerate properly and step a little further forward, thus entering the range of the Mine and suffering its wrath.
Mines cannot auto-acquire the same target at the same time. If one Zergling walks in the range of 5 Mines, only one of them will shoot. If one Immortal enters the range of 3 Mines at the same time, they will not fire at once but successively shoot (i. e. the first Mine will lock on it and shoot, after which the second Mine will lock on it and shoot, after which the third Mine will lock on it and shoot). You can circumvent this problem by manually targetting the desired target so Mines fire at once, but in this case Mines can overkill.
Mines need detection to acquire cloaked targets.
Mines deal splash damage to your troops, but not to your other Mines.
Mines do not trigger on morphed Changelings.
Mines do trigger on Hallucinations unless you have detection to reveal them.
