Abstract
A composition for forming a hydrogen peroxide based emulsion explosive which composition comprises: an oxidizer-phase comprising at least 35% by weight of hydrogen peroxide and at least 25% by weight of water, a fuel-phase comprising at least one primary oil type fuel with a flash point below 100° C. and at least one secondary oil type fuel with a flash point over 150° C. and at least one emulsifier, wherein the oxidizer-phase is discontinuously dispersed throughout the continuous fuel-phase. A method of preparing an emulsion type explosive composition is also disclosed.

A composition for forming a hydrogen peroxide based emulsion explosive which composition comprises;
- an oxidizer-phase comprising at least 35% by weight of hydrogen peroxide and at least 25% by weight of water,
- a fuel-phase comprising at least one primary oil type fuel with a flash point below 100° C. and at least one secondary oil type fuel with a flash point over 150° C., and
- at least one emulsifier, wherein the oxidizer-phase is discontinuously dispersed throughout the continuous fuel-phase.
A method of preparing an emulsion type explosive composition, which method comprises:
- providing an oxidizer-phase comprising at least 35% by weight of hydrogen peroxide and at least 25% by weight of water,
- providing a fuel-phase comprising at least one primary oil type fuel with a flash point below 100° C. and at least one secondary oil type fuel with a flash point over 150° C.,
- providing at least one emulsifier,
- forming an emulsion comprising the oxidizer-phase, the fuel-phase and the emulsifier, in which emulsion the oxidizer-phase is discontinuously dispersed throughout the continuous fuel-phase, and
- sensitizing the emulsion by adding gas filled compressible solid micro-balloons, and/or by generating gas bubbles by means of a gassing agent and/or by adding gas bubbles to the emulsion.
