That would be nice.  But I'm not sure why you're looking at coordinates.  Just select a mine from the list and look around in top-down to see which one was highlighted.  Also, I think the list is sorted by age?  So if you place the mines in the order you need them, you can just go down the list from top to bottom without having to wonder which ones are which.
