Abstract (en)

[origin: EP1457474A1] A water-in-oil emulsion explosive characterized by containing an ethylene vinyl acetate copolymer. It has excellent long-term stability. Even when stored under a load for as long as about one year, the explosive is less apt to suffer a decrease in explosive performance and coagulates only slightly in such a degree that it comes to have weakly coherent partial coagulates which can be easily disaggregated. Even after long-term storage, charging with the explosive can be easily conducted with a charger. Since the explosive has excellent water resistance, it is suitable also for blasting in a water hole.
