  • Patent number: 9157705
    Abstract: An relatively small anti-personnel mine device having a housing about 2 to about 3 inches in diameter, by about 2 to about 4 inches in length, which device projects a dispersion pattern of ? to ? inch diameter hard fragments over at least a 3 to 4 inch radius circle to neutralize a typical, buried, anti-personnel mine. The device contains about 125 to 190 grams of plastic explosive, which when detonated impacts a gas push plate against which an array of the fragments are lodged—the gas push plate and the fragments being encased in a puck shaped matrix of plastic or resin. The effect of the device is such that in addition to neutralizing the mine, the overburden atop the buried mine is expelled exposing the mine, providing enhanced safety in removal and a warning if the mine is daisy-chained to other mines.
