Cornish Mines Underground 3: the first set of photographs were taken in a very interesting disused Cornish Mine. An image of Dave above me descending a shaft that is around 260ft deep, daylight is just visible. This shaft is hard work to ascend as there is nowhere to rest and the exit keeps teasing you, as with any underground exploration safety is paramount.
The shaft has very large internal dimensions, which does not help the fear levels!
After a short walk we reach the main pumping shaft of the mine, Dave is standing beside a clack valve on the rising main. This was a device that allowed water to travel one way, it was lined with hide and when it worked a loud crack was heard, hence the name “Clack” Valve.
Stretching out over the pumping shaft and looking upwards I managed to get this image. The rising main is clearly seen with the pump rod which is in a state of collapse. When the shaft was open I have been told this was a great sight to see from the surface as long as somebody was holding onto your legs.
This image is looking down the shaft, just visible is a blockage which is usually under water.
A mine near Twelveheads showing part of a recent re-working in the 1980’s, this was an emergency exit and a main tramming level.
Another view of the drive in the mine showing the instability of the rock through which it was mined.
A final image of the level, the twin tracks can clearly be seen, how long this area will survive is uncertain, as the timberwork gradually rots away it will become more and more unstable.
The images below were taken in various mines in the Pendeen Area
This was a deep shaft around 300ft, to keep each other company we used two ropes. This is a site we will re-visit again.
Dave, it’s a long way up!
It can get quite wet exploring the old mines adit systems.
In the foreground is a flooded shaft with the remains an old winch half submerged. We did not go any further as the timbers holding up the roof and deads (unwanted rubble) was unstable and dangerous.
