Abstract
Systems and methods for chemoremediation or mechanical destruction of undetonated explosive materials. An explosive apparatus contains an explosive material in close proximity to a chemical reagent selected for its chemoremediative properties. A barrier is interposed between the explosive material and the chemical reagent to delay the chemoremediation of the explosive material. Alternatively a water expandable material may be incorporated into the explosive material, whereby upon exposure to moisture the water absorbing material will expand sufficiently to fragment the explosive material into initiation insensitive particles. Initiation insensitivity is achieved by incorporation of water, which acts as a desensitizing agent as well as fragmenting the explosive material into particles sufficiently small that they are below the critical diameter for explosive initiation. The present invention also relates to self-degradable, shaped explosive formulations, comprising an explosive material and a water expandable material.
