Explosive compositions for use in high temperature, reactive ground, or both, are disclosed. The explosive compositions can include an emulsion with a continuous organic fuel phase and a discontinuous oxidizer phase. The oxidizer phase can include one or more Group I or Group II nitrates.

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.

An explosive emulsion composition of the water-in-oil type, comprising between 80 wt. % and 95 wt. % of an oxidizer phase composition comprising at least 40 wt. % of ammonium nitrate (AN), and at least 15 wt. % of calcium nitrate (CN), and optionally one or more other secondary nitrate salts, between 5 wt. % and 20 wt. % of an organic phase comprising between 12 wt. % and 50 wt. % of one or more emulsifiers, between 50 wt. % and 88 wt. % of a fuel composition, in view of the total weight of the organic phase composition,
characterized in that the fuel composition comprises between 20 wt. % and 100 wt. % of a straight vegetable oil (SVO), and
wherein the explosive emulsion composition is stable and has a viscosity between 25,000 cP and 125,000 cP, as measured with a Brookfield viscometer with spindle size 7 at a frequency of 20 rpm at 30? C.

Emulsion explosives with gas bubbles that are resistant to in-borehole migration or coalescence are disclosed herein. Such emulsions can be sensitized by mechanically-introducing gas bubbles into the emulsion. Resistance to gas bubble migration and coalescence can be achieved by homogenization, without the need for bubble stabilization agents.
