my bad... should of zoomed in, the small pic made it look like an 830 we had up at Diavik
so what makes you investigate these things? the accident or the broken equipment?
Why?
Blasting companies blast according to what city council tells them, they distribute public warnings by mail to every household/appartment that they'll be blasting everyday at 6pm for the next week (example)
they use blast mats so why would anyone evacuate? you arent going to evacuate...
and what if they get pissed and throw it in your face because thats not what they want
bought a guy a sandwich once.... he spat on it and said "i want money for fawkin booze dumbass"
that was not cool
