Part of the back of the distribution boards; the rear of a giant remote transformer switch.
This is an elevator to move mine car loads of sand to the surface for cleaning and eventually glass production. Below is a flooded equipment vault. In front and behind is a loop through the larger tunnels in the mine. The horizontal braces supported electric cables for the mine carts.
