    My trin of thought went towards marine seismic survey and the use of intensifiers, Ok the air cannons in this case are sat in the medium and used to produce an almighty bang (and it is, every minuet - i worked in marine survey although my job was gravity and magnetics).
    this should explain the theory

    And this is an image of one of the cannons/guns

    Didn't do anything for the dust. Seems like it might have been more effective if the water cannon ignition was more simultaneous or perhaps slightly later than the demolition charges. But, that is certainly not my area of expertise.
