yes..easy to laugh...but look at the Mines in the Peak caving clubs have negotiated access agreements with...
Rowter James hall Maskhill Oxlow Nickergrove Merlins Knotlow Hillocks Water Icicle Tearsall pipe Caverns masson etc etc...
have a free access agreement or just a ยฃ1 to the farmer...no restrictions no limitations....
And the ones mining organisations are involved with..Alderley Edge..Oxclose..Magpie...Ecton...etc etc
No access or only limited to guided tours...
I know who i'd rather leave in charge!
OK, let's have a look at the situation with these ones you've cited as having access arrangements mishandled by mining groups.
Alderley Edge, where the bulk of the land is owned by the National Trust has access controlled by the Derbyshire Caving Club, so that's hardly a mining organisation for starters. Also, if you trouble to look on their website, for details of accessing the mines , they state "However, the National Trust impose certain conditions regarding leaders who must be DCC members". So, here the owner has allowed DCC to control access, but on condition one of their members accompanies the visiting party. Accompanies, not guides - there is a difference.
At Magpie mine PDMHS rent the surface remains from the Chatsworth Estate, who retain ownership of the mines and as far as I'm aware do not wish them to be generally accessible. I also understand that the fishermen on the Wye (who pay a lot more money for the fishing then we ever do in trespass fees) have issues with the silt that gets disturbed when you go up Magpie Sough, and following an incident involving the water bailiff and a group of explorers, the sough was gridded up as it is now. The last two times it's been opened for visiting are due to PDMHS negotiating with Chatsworth.
Oxclose I can't comment on as I don't know what the access situation is there, and Ecton, as I've previously said just requires a Trust-approved leader and signing of a disclaimer form. As for your comment about the access arrangements running counter to the spirit of other agreements, why should any owner be bound by such a perceived thing? We do not have a god-given right to go into any hole we like whenever we like, and to carry on as if we do is frankly childish, IMO - if we can't persuade the owner otherwise, we either abide by their wishes or go pirating and risk the consequences, which may include permanent sealing of a mine.
Now, are you seriously suggesting that the DCA or any other caving group would have been able to negotiate open access to these, given the owner's wishes? I seriously doubt it would be any different, regardless of who did the negotiation. It's also interesting to note that the mines you cite above as having had open access negotiated by caving clubs aren't either in sensitive locations or of major historical /archaeological importance, so is it any surprise that it's been possible to get liberal access agreements? I might also cite the case of Youd's level - PDMHS have the access control for that and it's no trouble to get in there.
Here's a challenge, let's see your caving groups who are so much better at getting access agreements than the mine societies negotiate one with the farmer who owns the land that Beans & Bacon mine is on....
Follow the horses, Johnny my laddie, follow the horses canny lad-oh!
