PROBLEM TO BE SOLVED: To provide a water-in-oil type emulsion explosive composition using a fluorine-containing emulsifier capable of performing rapid emulsification without deteriorating explosive performance and improving temporal stability.SOLUTION: A water-in-oil type emulsion explosive composition contains oils, an oxidant aqueous solution, an emulsifier and hollow microspheres and a fluorine-containing emulsifier of 0.05-8 pts.mass in 100 pts.mass of the emulsifier. The fluorine-containing emulsifier is an ester compound of a perfluoroalkyl carboxylic acid expressed by the general formula: CFCOOH (n=5-22) and sorbitan whose main component is 1,4-anhydrosorbitol.SELECTED DRAWING: None |
