Abstract

Provided is an emulsion explosive composition having voids/bubbles formed from one or more noble gases dispersed therein. Also provided is a method of manufacturing an emulsion explosive composition that includes mechanically and/or pneumatically infusing an emulsion explosive composition with a noble gas so as to create voids/bubbles formed from one or more noble gases. The noble gases can be contained within closed-cell micro-spheres that are dispersed throughout the emulsion explosive composition.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An emulsion explosive composition having dispersed therein voids/bubbles comprising one or more noble gases. 
     
     
         2 . The emulsion explosive composition of  claim 1 , wherein the noble gases are selected from the group consisting of Ar and He. 
     
     
         3 . The emulsion explosive composition of  claim 2 , wherein the voids/bubbles consist essentially of Ar, He, or a combination of Ar and He. 
     
     
         4 . The emulsion explosive composition of  claim 1 , wherein the voids/bubbles are in the form of closed-cell micro-spheres. 
     
     
         5 . The emulsion explosive composition of  claim 1 , wherein the voids/bubbles consist of one or more noble gases. 
     
     
         6 . The emulsion explosive composition of  claim 2 , wherein the voids/bubbles consist of Ar, He, or a combination of Ar and He. 
     
     
         7 . The emulsion explosive composition of  claim 1 , wherein the voids/bubbles are between 50 nm and 3 mm in size. 
     
     
         8 . The emulsion explosive composition of  claim 7 , wherein the voids/bubbles are between 10 μm and 3 mm in size. 
     
     
         9 . A method of manufacturing an emulsion explosive composition, comprising infusing an emulsion explosive composition with a noble gas so as to create voids/bubbles comprising one or more noble gases dispersed within the emulsion explosive composition. 
     
     
         10 . The method of  claim 9 , wherein the voids/bubbles consist essentially of Ar, He, or a combination of Ar and He. 
     
     
         11 . The method of  claim 9 , wherein the voids/bubbles are formed as closed-cell micro-spheres. 
     
     
         12 . The method of  claim 9 , wherein the voids/bubbles consist of one or more noble gases. 
     
     
         13 . The method of  claim 9 , wherein the voids/bubbles consist of Ar, He, or a combination of Ar and He. 
     
     
         14 . An emulsion explosive composition produced according to the method of  claim 9 . 
     
     
         15 . The emulsion explosive composition of  claim 1 , wherein the emulsion explosive is a water-in-oil emulsion comprising a discontinuous phase of an aqueous oxidizer solution having an oxidizer salt that is dispersed in a continuous phase of an organic fuel in the presence of one or more emulsifying agents. 
     
     
         16 . The emulsion explosive composition of  claim 1 , wherein the voids/bubbles are comprised of 85% by volume or more of the one or more noble gases. 
     
     
         17 . The emulsion explosive composition of  claim 1 , wherein the voids/bubbles are comprised of 85% by volume or more of one or more of Ar and He. 
     
     
         18 . The emulsion explosive composition of  claim 1 , wherein a density of the emulsion explosive composition is between 0.04 g/cc and 1.40 g/cc. 
     
     
         19 . The method of  claim 9 , wherein the voids/bubbles are comprised of 85% by volume or more of one or more of Ar and He.
