Who replaces the ropes ? Is it just random visitors or is it certain groups with an interest in the mine?
I was involved in the retrieval of some one way visitors several years back and my own feeling is that fixed ropes lowers the bar unnecessarily for such a trip.

Arguably, turning the two pitches into pull-throughs then opens up the possibility that someone who gets into a small amount of bother (no boat, bridge gone for example) then can't get out.
The counter to this is that the pitch has a cord so you can pull a rope back up again, but the odds of that being used correctly are not far short of zero.
And indeed there is a very valid argument that if you haven't got the skills you don't do the trip.
But that overlooks this here Internet, which attracts people from far and wide without the skills to recover from a problem - and without the experience to turn back because they understand this.
So, while the fixed ropes sure aren't the best of ideas, they're perhaps the least worst.
They do, however, rely on people not breaking them; nd removing them if they find them in a poor state before someone who can't deal with the problem gets into a lot of trouble.
