Abstract
A composition for forming a hydrogen peroxide-based emulsion explosive which composition comprises; an oxidizer-phase comprising at least 15% by weight of hydrogen peroxide and at least 15% by weight of water, a fuel-phase comprising at least one oil type fuel, a liquid emulsifier and at least one finely divided colloidal non-sensitizing solid adsorbent, 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 15% by weight of hydrogen peroxide and at least 15% by weight of water,
- a fuel-phase comprising at least one oil type fuel,
- a liquid emulsifier,
- at least one finely divided solid colloidal non-sensitizing adsorbent, 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 15% by weight of hydrogen peroxide and at least 15% by weight of water,
- providing a fuel-phase comprising at least one oil type,
- providing at least one liquid emulsifier,
- providing at least one finely divided solid colloidal non-sensitizing adsorbent,
- forming an emulsion comprising the oxidizer-phase, the fuel-phase, the emulsifier and the solid absorbent, 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.
