Report - Nant Hir No2. Colliery, October 2023

Previous report from from another member can be seen HERE.

Can't find a massive amount of history without repeating whats in the post above.

This site is located on the Side of Dulais valley above the village of Seven Sisters. There was once loads of small private mines on this hillside, at least 10 but all trace has been destroyed by later opencasting operations in the area. This includes the orignal Nant hir which was operational until the 1990s.

They mined high grade anthracite from the Red Vein until the late 2010s after being plagued with water issues it's whole working life.

One drift is now sealed with earth and the other is flooded to the roof just inside.

Manchester gate protecting the downhill slope into one of the now sealed drift.

Looking back towards the winder in the container.

General mining debris, Pipes/Cables, bagging for ventilation and bits of conveyer belt.

Part of another Manchester gate and electric box at the former entrance.

Machine for riddling the coal and removing all the small bits.

The remains of the fan show you what a high budget operation this was.

Just the remains of the return drift left.

The conveyer lives on. Quite handy preventing wet feet while getting a photo of inside.

Pro tip, don't walk over the mountain from Resolven in sideways rain.

Ha ha makes sense reading that. I was 'miring the pics but the whole vibe I was getting was a deep sense of dampness from every pic 🤣

Thats alright that, shame the workings are flooded

I see that the explosives magazine is still there - green box in background Pics 2 and 3. Those normally get cleared away quite quickly.

Was browsing through some plans and found the ones for this mine, so I thought Id tag it on the bottom.

Beautiful! I’d love to explore a colliery.

Plenty of surface remains - it was a very large industry at one time - but underground sites are hard to find and often too dangerous due to hazardous gases, the Coal Board have sealed by far the greater part of any old coal mines that would have been possible to enter.

Don't forget the coal authority and their sealing of mines by Heras fence panels. But yes it's very easy to get yourself killed in a coal mine if you are unprepared.
