T. L. Mining's Tim and Graham building the two concrete walls to recreate the shaft in the vault chamber. As the wall increased in height, a fill of grout was pumped to either side to a depth of one meter at a time. The grouting plant was set up on the hillside at the top of the mine site near to the village of Agneash and a constant supply of sand and cement along with water was required to keep the project going.
A total of six hundred tons of grout was pumped into the chamber to support the hanging wall on the left of the picture, which in turn is supporting the vaulted roof. The flow of grout can be seen in the bottom of the picture.
The mines group has now altered the bridge to span the concrete structure for inspection purposes. It is hoped the underground experience will eventually come through here.
