|Underground Works 2016|
A notable feature of Lefel Fawr is the huge stull above the incline skipway. Much photographed over the years, this was the scene of a massive fall some time ago which blocks direct access to the skipway, the main route down to the workings below.
Almost directly above the skipway timbers are noticeably sagging and steadily going rotten. After much consideration it was decided that the only feasible remedy was by adding support using concrete. When finished the intention is to cover the modern concrete with packwall in a way that is harmonious with the work of the old miners. (Phase1)
There is also a plastic tube which needs to be crawled through to reach this area. Due to it being restrictive and some distance above the floor, it can be quite difficult to get through. The plan is to replace this with a steel roadway in order to enable easier access. (Phase 2)
Above is the area of concern.
Before the temporary jack went in.
10th April 2016. Materials have been moved into the mine and shuttering is in place ready for the pouring of concrete.
16 and 17 April 2016
Saturday was mixing and pouring concrete, today I got some blockwork done. Behind the blocks is also being filled with concrete. Its a crying shame to cover in some of this lovely 'old mans' work, but leaving it would eventually lead to a catastrophic collapse with possible loss of access to the skipway.
Above is the view down, all the work is true to plumb.
Above is looking up from Lefel Fawr. Timber immediately above the ladder is quite solid but had to take the work round in the interests of solidarity so as form a substantial pier.
23rd and 24th April 2016
Weekend 30/04/2016 and 1/5/2016
Rails have been wedged at the top behind a timber and concreted in at the bottom to retain deadwork where the original timbers have rotted. The packwall will be extended down slope to cover the blockwork. The jack has also now been removed.
Packwall/cladding has also been started at the bottom.
It was started from little rock pegs driven into the packwall.
Weekend 7th and 8th May 2016
The packwall has been extended upwards over the blockwork and in places some brackets used for extra bonding.
Weekend 14th and 15th May 2016
Saturday 21st May 2016
Its a very sturdy job which harmonises well with the surroundings
The picture above shows the second tube as it was.

Above, mucked out and finished. Area beyond draining.
Beyond the second tube was a truck standing in water and mud. Tube left hand side behind the rock face.
As is now, truck moved back, area drained, new Steel Road beyond.
