Abstract
A water-in-oil emulsion explosive having a high resistance against dead pressing is obtained by adding a cushioning medium having a high impact energy-absorbing property to a water-in-oil emulsion explosive containing a continuous phase consisting of a carbonaceous fuel, a disperse phase consisting of an aqueous solution of inorganic oxidizer salt and an emulsifier.
Claims8
A water-in-oil emulsion explosive composition containing a continuous phase consisting of a carbonaceous fuel component, a dispersed phase consisting of an aqueous solution of inorganic oxidizer salt, an emulsifier, and a density adjusting agent, wherein the improvement comprises:
- - 45% by volume of a cushioning medium consisting of an organic substance having a bulk modulus of not higher than l.times.10.sup.11 dyne/cm.sup.2, said cushioning medium occupying not less than 2% by volume but less than 30% by volume in the total volume of the density adjusting agent and the cushioning medium.
