For all the length of the cable? Anyway, ships must let have routes to pass over those cables or we would partition the seas into small patches. Any ship passing over a cable between two mines can cut it. Edit: or do you mean mines anchored to the cable on the sea floor? That would make it easier to kaboom the cable instead of cutting it.
