South Africa gold mine: All 955 trapped workers freed

They had been trapped underground since a power cut struck on Wednesday night.

"Everybody's out," said James Wellsted, a spokesman for the operating firm Sibanye-Stillwater. He said there were "cases of dehydration and high blood pressure but nothing serious"

Would a 3,000 foot shaft not be equipped with a ladder way? I know it would be a long climb, but surely it would be better than being stuck at the bottom for so long. I'm sure Cornish miners regularly climbed from depths of up to 2,000 feet as part of their daily routine.

Actually its 3000 metres not feets (whatever they are)

I must admit I'm a little surprised there wasn't a generator to keep the ventilation going at least.

From BBC story.

"They had been trapped underground since a power cut struck on Wednesday night, and back-up generators failed to work."

Or possibly not, according to the Sibanye-Stillwater press release (https://thevault.exchange/?get_group_doc=245/1517545811-Sibanye-StillwatersafelybringsBeatrixemployeestosurfaceafterpoweroutage2Feb2018.pdf) 64 were trapped at 1 shaft, 272 at 4 shaft and 955 at 3 shaft.
http://www.goldfields.com/reports/rr_2009/tech_beatrix.php  ,
1 is 913m, 3 is 1447m and 4 has a total depth (surface shaft & sub-shaft) of 2200m

Mind these are 2009 figures...


Don't look so embarrassed, it's a family trait...

I love the way that it is described as a shallow to intermediate depth operation...

I worked on a gold mine in SA about 20 years ago and worked about 2800m underground. 2200m isn’t really deep with regards to gold mines (but is actually quite deep!)

I bet that was hot!

What were the walls like? Did you get a lot of bursts?

I worked at West Driefontein gold mine. Temperatures ranged from 25-40 degrees. Hanging walls was ok, had the odd burst now and again. The nearby Kloof mine had many more bursts than we did.

Wall bursts, on a much slower and less violent scale, in Welsh slate mines. Oakley / Cwm DE Floor springs to mind!
