CPL Boulby Mine, No 3 Shaft, known as the tailings shaft.
MP1 Resolution has been involved with some maintenance work on one of the sea bed valves (as far as I am aware, friends).
Inside the larger building there is a winding engine, which services the tailings tunnel.
There are two large pipes (inlet & outlet) which run down the LH side of the mile long tunnel. There is a narrow gauge railway track for the service personnel to transport themselves and tools from pit bottom to the far end, 1 mile.
From the pit bottom to the end of the tunnel there is an upward gradient, which allows water to flow to the shaft sump for pumping up to the pump station.
At the ½ mile mark there is a side road to the left where the ocean valve assembly is.
From this point to the end of the tunnel there is only one pipe. At the end there is another LH side road where the other ocean valve assemble is.
The full length of the tunnel is ventilated by a small steel duct, for some distance then & 18" canvas vent goes to the end, which is suspended at shoulder height on the RH side.
Sea water is taken in and pumped to the plant {under the main road} from the pump station midway up the shaft. Likewise unwanted water can be returned to the sea, hence inlet/outlet pipes.

No. 3 shaft - been down it many a time {26 yrs U/G}.
1st valve is at ½ mile, 2nd at 1 mile.
