Abstract: An explosive, in particular a water-in-oil emulsion explosive, comprising a water-based explosive composition and a gas, wherein the gas is infused with two different ranges of sizes of nanobubbles, to provide controlled hotspots for detonation to improve emulsion stability and detonation sensitivity. Into the Nano Bubble tank (31) are fed the pressurised gas in water through valve (26) and also a sample is fed into the Nano Bubble tank (31). This then provides the NanoBubble Input NBIbp1 to be fed by NB Feed Pump (33) into static mixer (51). Also fed to the Static Mixer (51) by matrix pump (41) is the explosives containing PIBSA (Poly-Iso-Butylene Succinic Anhydride) in emulsion form as Emulsion Input EInp1 from Emulsion Matrix truck.

Abstract: An explosive composition is provided which includes a hydrocarbyl polyamine emulsifier, characterised by a straight link between the hydrocarbyl group and said polyamine. A method of forming the composition is also provided, characterised by the emulsifier being produced by reacting an alkanolamine with a hydrocarbyl halide.

Abstract: Solid water-in-oil emulsion explosive compositions comprising a discontinuous emulsion phase formed of an aqueous solution of an oxidizer salt and a continuous emulsion phase formed of a solid carbonaceous fuel derived from an oleaginous liquid. The continuous phase provides a self-sustaining matrix. A solid non-hygroscopic oxidizer salt, such as ammonium perchlorate, is dispersed in the emulsion in a solid granular form. Void cells are also dispersed within the emulsion to provide a void volume of at least 5%. The explosive compositions may be formulated to be sensitive to No. 8 blasting caps. Processes for forming the explosive compositions include the use of an oleaginous liquid of a polyester and styrene monomer mixture, which is emulsified with an aqueous solution of oxidizer salt without the addition of an emulsifying agent. The explosive composition may be formed as a unitary product or transformed into granular particulate form.

Abstract: Explosive composition of water-in-oil, containing as a continuous phase a carbonaceous fuel and as a discontinuous phase an oxygen-releasing aqueous salt solution, the continuous phase containing a water-insoluble lipophilic viscosity index improver for the purpose of controlling the consistency.
