Inorganic oxidizer salt aqueous blasting compositions containing a nitroparaffin

Claim 1

IN AN INORGANIC OXIDIZER SALT EXPLOSIVE COMPOSITION OF THE AQUEOUS SLURRY TYPE, THE IMPROVEMENT COMPRISING, FROM 3 TO 40 WEIGHT PERCENT OF A NITROPARAFFIN COMPONENT, AS A SENSITIZER, SELECTED FROM THE GROUP CONSISTING OF NITROPARAFFINS CONTAINING FROM 1 TO 3 CARBON ATOMS IN THE MOLECULE, AND MIXTURES THEREOF, AND SAID SLURRY ALSO CONTAINING A SUPPLEMENTAL SENSITIZER SELECTED FROM THE GROUP CONSISTING OF PARTICULATE ALUMINUM, POWDERED COAL, DINITROTOLUENE, AND A HYDROCARBON OIL WHEN THE TOTAL AMOUNT OF SAID NITROPARAFFIN SENSITIZER COMPONENT OF SAID SLURRY IS BELOW ABOUT 9 PERCENT.

Claim 3

A METHOD FOR THE MANUFACTURE OF AN INORGANIC OXIDIZER SALT EXPLOSIVE OF THE AQUEOUS SLURRY TYPE CONTAINING FROM 3 TO 40 WEIGHT PERCENT OF A NITROPARAFFIN COMPONENT, AS A SENSITIZER, SELECTED FROM THE GROUP CONSISTING OF NITROPARAFFINS CONTAINING FROM 1 TO 3 CARBON ATOMS IN THE MOLECULE, AND MIXTURES THEREOF, AND GUAR GUM AS A THICKENER, WHICH COMPRISES THE STEPS OF FORMING A PREMIX OF A HYDRATABLE PORTION OF THE SAID GUAR GUM AND A PORTION OF THE CONTEMPLATED OXIDIZER SALT COMPONENT, IN A RATIO OF SAID SALT TO SAID GUM OF ABOUT 3:1 TO 5:1, AND THE SAID PORTION OF GUAR GUM NOT EXCEEDING ABOUT 1 PERCENT OF THE FINISHED SLURRY PRODUCT; PARTIALLY GELLING SAID NITROPARAFFIN SENSITIZER AND MIXING THE RESULTING PARTIAL GEL WITH NOT MORE THAN 20 PERCENT OF ITS WEIGHT, OF ANOTHER PORTION OF THE SAID OXIDIZER SALT, TO FORM A RESULTING NITROPARAFFIN SLURRY; ADMIXING THE PREMIX, FORMED AS ABOVE DESCRIBED, WITH THE TOTAL CONTEMPLATED WATER COMPONENT OF SAID SLURRY TO PERMIT HYDRATION OF THE SAID GUAR GUM PORTION; ADMIXING THE REMAINING OF THE SAID OXIDIZER SALT AND GUAR GUM INGREDIENTS WITH THE THUS THICKENED AQUEOUS MIXTURE, AND THE LAST SAID ADDED GUAR GUM BEING CROSSLINKABLE; ADMIXING THE ABOVE-DESCRIBED NITROPARAFFIN SLURRY WITH THE RESULTING AQUEOUS MIXTURE, AND ALSO ADMIXING A SUPPLEMENTAL SENSITIZER SELECTED FROM THE GROUP CONSISTING OF PARTICULATE ALUMINUM, POWDERED COAL, DINITROTOLUENE, AND A HYDROCARBON OIL, WITH SAID RESULTING AQUEOUS MIXTURE, AS THE LAST ADDED INGREDIENT, WHEN THE TOTAL AMOUNT OF SAID NITROPARAFFIN SENSITIZER COMPONENT OF THE RESULTING SLURRY EXPLOSIVE PRODUCT IS BELOW ABOUT 9 PERCENT; AND RETAINING THE RESULTING SLURRY MIXTURE UNDER CONDITIONS FOR EFFECTING CROSS-LINKING OF GUAR GUM THEREIN TO REGULATE CONSISTENCY OF SAME TO A PREDETERMINED DEGREE.

Claim 4

A METHOD FOR THE MANUFACTURE OF AN INORGANIC OXIDIZER SALT EXPLOSIVE OF THE AQUEOUS SLURRY TYPE CONTAINING FROM 3 TO 40 WEIGHT PERCENT OF A NITROPARAFFIN COMPONENT, AS A SENSITIZER, SELECTED FROM THE GROUP CONSISTING OF NITROPARAFFINS CONTAINING FROM 1 TO 3 CARBON ATOMS IN THE MOLECULE, AND MIXTURES THEREOF, AND GUAR GUM AS A THICKENER, WHICH COMPRISES THE STEPS OF FORMING A PREMIX OF A HYDRATABLE PORTION OF THE SAID GUAR GUM AND A PORTION OF THE CONTEMPLATED OXIDIZER SALT COMPONENT, IN A RATIO OF SAID SALT TO SAID GUM OF ABOUT 3:1 TO 5:1, AND THE SAID PORTION OF GUAR GUM NOT EXCEEDING ABOUT 1 PERCENT OF THE FINISHED SLURRY PRODUCT; PARTIALLY GELLING SAID NITROPARAFFIN SENSITIZER AND MIXING THE RESULTING PARTIAL GEL WITH NOT MORE THAN 20 PERCENT OF ITS WEIGHT, OF ANOTHER PORTION OF THE SAID OXIDIZER SALT, TO FORM A RESULTING NITROPARAFFIN SLURRY; ADMIXING THE PREMIX, FORMED AS ABOVE DESCRIBED, WITH THE TOTAL CONTEMPLATED WATER COMPONENT OF SAID SLURRY TO PERMIT HYDRATION OF THE SAID GUAR GUM PORTION; ADMIXING THE REMAINING OF THE SAID OXIDIZER SALT AND GUAR GUM INGREDIENTS WITH THE THUS THICKENED AQUEOUS MIXTURE, AND THE LAST SAID ADDED GUAR GUM BEING CROSSLINKABLE; ADMIXING THE ABOVE-DESCRIBED NITROPARAFFIN SLURRY WITH THE RESULTING AQUEOUS MIXTURE, AND ALSO ADMIXING A SUPPLEMENTAL SENSITIZER SELECTED FROM THE GROUP CONSISTING OF PARTICULATE ALUMINUM, POWDERED COAL, DINITROTOLUENE, AND A HYDROCARBON OIL, WITH SAID RESULTING AQUEOUS MIXTURE, AS THE LAST ADDED INGREDIENT, WHEN THE TOTAL AMOUNT OF SAID NITROPARAFFIN SENSITIZER COMPONENT OF THE RESULTING SLURRY EXPLOSIVE PRODUCT IS BELOW ABOUT 9 PERCENT; AND RETAINING THE RESULTING SLURRY MIXTURE UNDER CONDITIONS FOR EFFECTING CROSS-LINKING OF GUAR GUM THEREIN TO REGULATE CONSISTENCY OF SAME TO A PREDETERMINED DEGREE.
