Abstract:
Before use of the glycerol nitrate as an industrial
explosive by Nobel in the 1860s, the black powder
with half the explosive power of TNT was the only
blasting explosive.
However, with the subsequent development of
various types of explosives with strong explosive power
and diverse performances as dynamite, work efficiencies
in the fields of mining, tunneling, construction and
excavation have been broadly improved, thus industrial
explosives emerging as an essential product to save time
and expenses.
