I saw a few failures when I worked for a spell in the repair industry, every piece of control circuit wiring in a 3.3Kv belt starter burnt out, came from Williamsthorpe Colliery, it had been operated by the isolator, which was also in a bad way.
Seen a few flashed up HV starters underground, including an 11Kv breaker, had an 18th of an inch of soot on the walls of the breaker.

I'm hoping there is still some interest in this

With Govt Department Restructures & "server changes" unfortunately many of the Links above are dead.

So....Better to go the the Updated Regulator Web Pages & search "electric" or "words" from the titles of the incidents of the specific items above.

I recall when I worked at BG's Marbleagis Mine when the new safety and Health rules were being introduced throughout all industries in the UK, we elecs had to take a course on mounting grinding wheels, originally it was a weeks course, condensed into a day's course!!!! Most bloody boring 10 hours I've ever spent in my life!!
Mind I did learn some things from it, and still have all the paperwork somewhere. I kept it all just in case.

I might also add, when the NSW government decided to rewrite the CMA in 84, in response to the Appin explosion, the new Act was to take effect immediately after publication. BIG PROBLEM, there were no printed copies of the Act anywhere. so how the EFF, could we abide by new regualtions if they weren't publicly available???
That was only one EFF up!!
Our Engineer at Angus Place at the time went out his way to get an abridged copy, which he did and set out to make a printed course to educate us dimwits. Good job Kerry, you put a lot of time into the training manuals for both the mining side and engineering sides.
There were many bloopers, NOT KERRY's I might add, like "all electrical staff had to be supervised....OK who supervises the supervisors?? That was changed very quickly by the government. Many more bloopers were found like qualifications of elecs and fitters, that could have stopped all coal production. So many of us in the 80's were NCB trained migrants, then those elecs and fitters who came from outside industry wouldn't be recognised. Again soon rewritten to include some 75% of the NSW coal industries tradesmen.

I wonder if that was the reason the UK Coal Mines Act of 1954 didn't take effect until 1956?
