Abstract
An explosive in granulated or particulate form, wherein at least a part of the granules comprises an emulsion, having a continuous fuel phase and a discontinuous oxidizer phase containing oxidizing salts, and wherein the fuel phase is soft or deformable and at least a part of the oxidizing salts in the discontinuous phase is in solid crystalline or amorphous form. A method for the manufacture of an explosive in granular or particluate form comprises the steps of, forming an emulsion having a continuous fuel phase and a discontinuous oxidizing phase containing oxidizing salts, solidifying at least a part of the oxidizing salts in the discontinuous phase and granulating the emulsion. The granulated explosive may be charged, e.g. by blow-loading, into a hole in a material and initiated.
