ABSTRACT:
A thickened, aqueous slurry explosive composition containing a soluble organic nitrate sensitizer is provided which has improved rheological properties. Use in the composition as a thickener, of a mixture of an unmodified guar gum and a hydroxypropyl-modified guar gum provides a composition which retains flowability for an hour or more for easy extrusion packaging yet achieves a high level of gel strength and cartridge rigidity within a day after packaging.
