Fleet is under mining battle cooldown??

[53696699]

Trying to hit a couple of enemy fleets while they were exploiting. Kept getting the message Fleet is under mining battle CD: cannot operate. It appears to be at least a 10 minute window of safety for exploiters. Can someone elaborate on this please?
