COAL MINE FATALITY - On March 23, 2003, a 51-year-old section foreman, with 25 years mining experience, sustained serious burn injuries from a 480-volt receptacle located on a section power center. The injuries apparently occurred when the victim used the energized receptacle to detonate explosives while developing a boom-hole. He died at a burn center on April 10, 2003. The victim was not a qualified electrician or a certified shot-firer.

"Backpacker" magazine said it best, though... "Sometimes the doofus dies."

I've worked with explosives before (and yes I do have an explosives licence) and doing something as stupid as this would just never be done anywhere here.
This guy got what was coming to him, I hate to say.

I was an explosives engineer, [22 years Royal Ordnance]. No licence, [strictly for civvies].
The 480v did not detonate the explosives, period. Only a proper detonator could do that. This guy probably used the voltage to set off an electric detonator. I guess the injuries were caused at the panel shown, by a short, since only a complete wazzock would have put his contactor next the blowhole. [ Analagy: sawing off the branch you're standing on.] In which case, this was purely an electrical accident and the link to explosives is not an issue, except to the media ignoramusses.
I will say that eventually you can get complacent about hazards in any profession, so this guy deserves our sympathy, where but for the grace of God....

In my case, I broke both my eardums.

Take care today.

This fatality was determined to be chargeable to the coal mining industry on May 15, 2003.

the guy was not qualified / certified but companies most likely had to install yet another idiot-proof modification to equipment throughout the coal mining industry to prevent this type of accident from recurring and of course, more restrictions, more $$$, more training, more lost time

Dave Mustane is the founder of the Metal band 'Megadeath'

Sorry Gloria Dirty Harry said it before Dave.

But who knows, his writers may have ripped it from someone else as well.
