Any safety issues should be reported to the mine owners please, but this has reached the right address anyway.
I am not sure exactly where you mean as there are two plank walks, one about half way up the main ladderway, safety line was installed by SCMC as was the in situ rope on the ladder, with the authority of CMT who, as mine owners should always be consulted.
There is no plank walk "on" Lefel Fawr, they are above it.
The other plankway is at the highest stope and is not used much as the area is rarely visited.
Please note that Cambrian Mines Trust do not accept any responsibility for fixed aids, also that the workings above Lefel Fawr are very loose and have already been the scene of one accident. A notice has been posted in the mine.
They should not be visited except by the most experienced.
I am also curious as to why Maillons need replacing, bolt loose, almost rusted through, whatever?
Please advise.
