A synergistic composition of emulsion explosive useful for blasting in surface mines and a process of making the emulsion explosive

This invention relates to a synergistic composition of emulsion explosive useful for blasting in surface mines and a process for making the emulsion explosive. This synergistic composition is water-in oil site mixed emulsion explosive, booster sensitive and detonates in the 50mm, 83mm and larger sizes which can be used in shovel and deep hole blasting in surface mines. The velocity of detonation is in the range of 4500- 4800 m/s. The developed product is water resistant and sustain the hydrostatic pressure in deep bore holes up to 45m depths. The energy values of this product are in between 575 to 590 kcal/kg and enough for rock fragmentation in shovel as well as deep hole blasting.
