  • SYSTEMS AND METHODS FOR HOMOGENIZING MECHANICALLY-GASSED EXPLOSIVES
    Publication number: 20250130030
    Abstract: Systems and methods for delivering explosive mixtures with gas bubbles that are resistant to in-borehole migration or coalescence are disclosed herein. Such explosive can be sensitized by mechanically introducing gas bubbles into the explosive matrix in a number of gassing stages. Resistance to gas bubble migration and coalescence without the need for bubble stabilization agents can be achieved by homogenization in a number of homogenizing stages.

  • Inhibited emulsions for use in blasting in reactive ground or under high temperature conditions
    Patent number: 11346643
    Abstract: Methods of delivering inhibited emulsions are provided. The methods can include mixing an emulsion with a separate inhibitor solution to form the inhibited emulsion. Inhibitor solutions including water, an inhibitor, and a crystallization point modified are provided. Systems for delivering inhibited emulsions are also provided.

  • Method and system for manufacture and delivery of an emulsion explosive
    Publication number: 20070277916
    Abstract: A method for manufacture and delivery of an emulsion explosive having a discontinuous oxidizer solution phase, a continuous fuel phase, and an emulsifier, the method comprising: (a) providing an emulsion manufacturing system; (b) conveying an oxidizer solution phase to the emulsion manufacturing system at a pre-determined pressure; (c) conveying a fuel phase to the emulsion manufacturing system at a pre-determined pressure; (d) forming an emulsion from the oxidizer solution and the fuel phases using only a portion of the pre-determined pressures so as to provide a usable residual pressure after the formation of the emulsion; and (e) utilizing the residual pressure to non-mechanically deliver the emulsion to a pre-determined location.
