The PDCMG tell us that following the failure of a couple of timbers at the bottom of the Draenen entrance series scaffolded shaft, work has begun on inspecting and replacing the current shuttering. A team from Morgannwg and Brynmawr CCs has started the work, which involves very carefully knocking out the current timbers and replacing them one at a time. Most of the newly-installed timbers are permanent, but at the moment there are a couple of pieces towards the bottom of the shaft which are temporary and will be re-engineered on future trips.
Teams are being asked to take extra care in the scaffolded shaft for the next couple of months. Work on the side walls of a shaft inevitably disturbs the choke, and some movement is likely.
