Precision Blasting

Like most facets of engineering, precision blasting strives to use the least amount of consumables possible while achieving an acceptable result. Much like how one can overbuild anything in engineering, anyone can successfully blast something given enough explosives. The craft is to combine economy, control and safety in order to minimize noise, dust and general disturbance while maximizing fragmentation and desired breakout shape. A good blaster can make a tall or shallow pile, throw it left or right, or minimize the throw, all depending on what mucking equipment will be used. Anyway, this is all going somewhere: in March 2004 I was on a field trip out to Milton, ON to see an open pit blast at a Dufferin Aggregates facility. The blast went off perfectly despite some water in the holes.

Beautiful shot absolutely perfect delay pattern and powder factor wish we could get some of the quarries we blast to lay us out some long faces like that! Just awesome!

Back in the 70zz i took several courses at Sheidan college that used to be a little further up the road. When they blasted you could feel it but not hear it.
