| 简介 |
This invention relates to a base emulsion for an emulsion explosive, the base emulsion being a re-pumpable water-in-oil emulsion and comprising : a continuous fuel phase, comprising a liquid hydrocarbon fuel; and an aqueous discontinuous oxidiser phase, dispersed in the fuel phase, the oxidiser phase comprising water, ammonium nitrate and sodium perchlorate. This invention also relates to a sodium nitrite-containing sensitizing solution, for sensitizing such a base emulsion, the sensitizing solution comprising sodium perchlorate. This invention extends, further, to a two-component explosive system comprising such a base emulsion and such a sensitizing solution. Finally, the invention extends to a method of loading a borehole with such a base emulsion and such a sensitizing solution to provide a sensitized emulsion explosive loaded in the borehole; and to such explosive. |
