A friend of mine work for a company that transport explosive for mining and fire won't ignite the explosive. Without a detonator and an electric discharge the stuff can be handle safely. Maybe in Guana they still use some kind of explosive sensitive to fire but I doubt it. A canadien gold mine will probably use the same kind of explosive as here in Canada.
Just my 2 cents.
That’s definitely an sight from a post blast. You’re supposed to separate detonators from the high explosives but who knows if that’s what happened. Consider that you live in Canada, where there’s laws governing the safe transport of explosives. Those laws don’t exist in Ghana or they’re easily not followed.
You’re friend is also dead wrong. Fire will definitely ignite explosives, it might not make them high order, which is the chemical reaction that proceeds faster than the speed of sound thus producing the blast wave. There’s a difference between ignition or burning and detonation.
All explosives are sensitive to heat, shock or friction in varying degrees.
