Latest photo pick: 20Ton Construction Blast

This is actually a series, so if 20 tons of explosives interests you (why wouldn’t it??) then go to the album and view it as a slide show (1 second transition).

    But why?

    Do we need a reason Jo? =)
    The cutting through the hill had to go another 10 meters down. However, the deeper we went the more solid the rock became to the point where it couldn’t be broken out with machines. The most effective way of getting it out was to blast. Hundreds of holes were drilled into the rock and filled with the 20 tons of explosives. Hole spacing and amount of explosive were proportioned to produce a broken rock size that would be easily transferable, eg. not massive chunks and not sand. Detonation was done remotely with each hole timed to go off in a wave that would maximize effect.

    Mate, that was awesome! There should be more photo sets like that in the world.
    The only thing better than the photos themselves was your description of the process (above), which deserves to be in the main post itself, rather than languishing in the comments section 🙂
