IMPROVED WATER-IN-OIL EMULSION EXPLOSIVE COMPOSITION SENSITIVE TO A NO.6 DETONATOR EVEN WHEN PREPARED UNDER LOW SHEAR LOW SPEED MIXING CONDITIONS AND METHOD FOR PRODUCTION OF SUCH COMPOSITIONS

摘要

An improved water-in-oil emulsion explosive composition sensitive to a commercial No. 6 detonator or detonating cord in diameters of 25 mm. and above at temperatures down to 5degree C when prepared under low shear low speed mixing conditions which comprises the combination of an aqueous solution comprising one or more inorganic oxidiser salts such as herein described, a sensitising liquor such as herein described, water and a gassing accelera such as herein described with a fuel phase comprising bydrocarbon fuels and emulsifiers such as herein described and a density controlling agent such as herein described, the sensitivity of the composition being imparted by the presence of said sensitising liquor in an amount of from 2% to 40% by weight of the total weight of the composition.
