  • Process and apparatus for fragmenting rock and like material using explosion-free high pressure shock waves
    Patent number: 4669783
    Abstract: A technique for fragmenting rock or other relatively hard and/or compact material without the use of explosives is disclosed herein. In accordance with this technique, an elongated, blind opening is provided in the rock or other material to be fragmented and a pulse of water having a relatively high peak pressure and a relatively rapid rise time is directed into the elongated opening without the use of explosives to produce the pulse, whereby to produce a shock wave in the rock or other material sufficient to fragment it. In an actual embodiment, this explosion free pulse of water has a peak pressure of about 80,000 psi and a rise time of about one millisecond.
