A method and composition are provided for preparing slurry explosive formulations characterized in containing separate liquid and particulate phases. The liquid phase is a detonation insensitive paste-like pre-mix composition having an extended shelf life and being adapted for ultimate combination with sufficient particulate material to form an efficient explosive. The pre-mix composition includes a gum or thickener but is not gelled or cross-linked, in order to facilitate ultimate on-site mixing in a rapid manner and without the need for complex equipment.

A method of preparing slurry explosive compositions containing distinct, liquid and particulate phases, which method comprises the steps of: compounding at a first location remote from a site of possible use, a long term storable non-explosive detonation insensitive liquid phase pre-mix having a stable viscosity; subsequently transporting said pre-mix to a second location in the vicinity of the site of possible use; and subsequently dispersing at said second location the particulate phase into said liquid phase by simple mechanical mixing techniques and thereby forming a slurry explosive mixture in the vicinity of the site of composition use. A non-explosive detonation insensitive storeable non-gelled thick liquid phase pre-mix composition with comparatively stable viscosity for subsequent use in preparing a slurried explosive upon being combined with additional material, which pre-mix composition comprises, on a weight basis: (a) from about 30% to 50% water, (b) from about 10% to 50% of an inorganic oxidizing salt, (c) up to about 20% of a liquid, organic fluid extender, (d) from about 0.5% to about 2.0% of a thickening agent consisting essentially of a non-self cross-linking thickener, said composition being free of any self cross-linking thickener.
