Abstract
Abstract An explosive blasting composition of the gel or slurry type which retains its sensitivity to detonation after being agitated or worked and method of making such composition are provided wherein a small amount of collector is added to the composition comprised of a stable dispersion of a metallic sensitizer and/or fuel particle throughout a thickened solution or fluid phase containing at least one inorganic oxidizer salt. The collector remains in solution throughout the fluid phase of the composition.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
A METHOD FOR PREVENTING THE LOSS OF SENSITIVITY OF A GASCONTAINING BLASTING COMPOSITION UPON BEING WORKED WHICH COMPOSITION COMPRISES A CONTINUOUS THICKENED SOLUTION PHASE HAVING DISSOLVED THEREIN AT LEAST ONE INORGANIC OXIDIZER SALT AND METALLIC PARTICLES AS FUEL AND/OR SENSITIZER DISPERSED THROUGHOUT THE SOLUTION PHASE WHICH METHOD INCLUDES INCORPORATING INTO THE SOLUTION PHASE A SMALL AMOUNT OF A MISCIBLE, LIQUID COLLECTOR, WHICH IS CAPABLE OF CAUSING FLOATATION OF THE METALLIC PARTICLES IN THE SOLUTION PHASE WHEN SUCH PHASE IS NOT THICKENED AND WHICH EETAINS ITS LIQUIDITY AND MISCIBILITY AT INTENDED TEMPERATURES OF WORKING.
Claim 2
Independent Claim
93 words
A METHOD FOR PREVENTING THE LOSS OF SENSITIVITY OF A GASCONTAINING BLASTING COMPOSITION UPON BEING WORKED WHICH COMPOSITION COMPRISES A CONTINUOUS THICKENED SOLUTION PHASE HAVING DISSOLVED THEREIN AT LEAST ONE INORGANIC OXIDIZER SALT AND METALLIC PARTICLES AS FUEL AND/OR SENSITIZER DISPERSED THROUGHOUT THE SOLUTION PHASE WHICH METHOD INCLUDES INCORPORATING INTO THE SOLUTION PHASE A SMALL AMOUNT OF A MISCIBLE, LIQUID COLLECTOR, WHICH IS CAPABLE OF CAUSING FLOATATION OF THE METALLIC PARTICLES IN THE SOLUTION PHASE WHEN SUCH PHASE IS NOT THICKENED AND WHICH EETAINS ITS LIQUIDITY AND MISCIBILITY AT INTENDED TEMPERATURES OF WORKING.
Claim 3
Dependent Claim
25 words
A method according to claim 1 which includes the additional step of adding a frother to the fluid phase to stabilize and control bubble size.
Claim 4
Dependent Claim
13 words
A method according to claim 1 wherein the collector is a fatty acid.
Claim 5
Dependent Claim
13 words
A method according to claim 3 wherein the fatty acid is oleic acid.
Claim 6
Dependent Claim
12 words
A method according to claim 1 wherein the collector is a soap.
Claim 7
Dependent Claim
24 words
A method according to claim 2 wherein the frother is selected from the group which consists of polypropylene glycol methyl ether and silicone resin.
Claim 8
Dependent Claim
12 words
A method according to claim 1 wherein the metallic particles are aluminum.
Claim 9
Dependent Claim
92 words
IN AN EXPLOSIVE COMPOSITION COMPRISING A THICKNEED SOLUTION PHASE OF AT LEAST ONE OXIDIZING SALT AND METALLIC PARTICLES AS FUEL AND/OR SENSITIZER DISPERSED THROUGHOUT THE SOLUTION PHASE THE IMPROVEMENT COMPRISING, IN THE SOLUTION PHASE, A SMALL AMOUNT OF A MISCIBLE,LIQUID COLLECTOR, WHICH IS CAPABLE OF CAUSING FLOTATION OF THE METALLIC PARTICLES IN THE SOLUTION PHASE WHEN SUCH SOLUTION PHASE IS NOT THICKENED AND WHICH RETAINS ITS LIQUIDITY AND MISCIBILITY AAT INTENDED TEMPERATURES OF WORKING, TO PREVENT THE METALLIC PARTICLES FROM BECOMING WETTED UPON WORKING THEREBY CAUSING THE COMPOSITION TO LOSE ITS SENSITIVITY.
Claim 10
Dependent Claim
92 words
IN AN EXPLOSIVE COMPOSITION COMPRISING A THICKNEED SOLUTION PHASE OF AT LEAST ONE OXIDIZING SALT AND METALLIC PARTICLES AS FUEL AND/OR SENSITIZER DISPERSED THROUGHOUT THE SOLUTION PHASE THE IMPROVEMENT COMPRISING, IN THE SOLUTION PHASE, A SMALL AMOUNT OF A MISCIBLE,LIQUID COLLECTOR, WHICH IS CAPABLE OF CAUSING FLOTATION OF THE METALLIC PARTICLES IN THE SOLUTION PHASE WHEN SUCH SOLUTION PHASE IS NOT THICKENED AND WHICH RETAINS ITS LIQUIDITY AND MISCIBILITY AAT INTENDED TEMPERATURES OF WORKING, TO PREVENT THE METALLIC PARTICLES FROM BECOMING WETTED UPON WORKING THEREBY CAUSING THE COMPOSITION TO LOSE ITS SENSITIVITY.
Claim 11
Dependent Claim
13 words
A composition according to claim 8 wherein the collector is a fatty acid.
Claim 12
Dependent Claim
13 words
A composition according to claim 9 wherein the fatty acid is oleic acid.
Claim 13
Dependent Claim
21 words
A composition according to claim 8 containing, in addition, a small amount of a frother to stabilize and control bubble size.
Claim 14
Dependent Claim
24 words
A composition according to claim 11 wherein the frother is selected from the group which consists of polypropylene glycol methyl ether and silicone resin.
