Abstract
Water-in-oil emulsion explosive compositions containing (e) nitromethane gelatinized product obtained by mixing nitromethane with a gelatinizer for nitromethane and (f) hollow microspheres and/or (g) bubbles formed from a chemical foaming agent in a water-in-oil emulsion composition consisting of (a) ammonium nitrate or ammonium nitrate and the other inorganic oxidizer salts, (b) water, (c) an oil and/or wax and (d) a sorbitan fatty acid ester surfactant.

Water-in-oil emulsion explosive compositions obtained by dispersing a mixture of (a) a gelatinized nitromethane product obtained by mixing nitromethane with a gelatinizer for nitromethane and (b) hollow microspheres in a water-in-oil emulsion composition comprising (i) ammonium nitrate or a mixture of ammonium nitrate and at least one other inorganic oxidizer salt, (ii) water, (iii) at least one of an oil and wax, and (iv) a sorbitan fatty acid ester surfactant.
Water-in-oil emulsion explosive compositions obtained by dispersing (a) a gelatinized nitromethane product obtained by mixing nitromethane with a gelatinizer for nitromethane and (b) bubbles in a water-in-oil emulsion composition comprising (i) ammonium nitrate or a mixture of ammonium nitrate and at least one other inorganic oxidizer salt (ii) water, (iii) at least one of an oil and wax and (iv) a sorbitan fatty acid ester surfactant, said bubbles having been formed by adding a chemical foaming agent to the water-in-oil emulsion composition before or after the gelatinized nitromethane product is added to the water-in-oil emulsion composition.
Water-in-oil emulsion explosive compositions obtained by dispersing a mixture of (a) a gelatinized nitromethane product obtained by mixing nitromethane with a gelatinizer for nitromethane, (b) hollow microspheres in a water-in-oil emulsion composition comprising (i) ammonium nitrate or a mixture of ammonium nitrate and at least one other inorganic oxidizer salt (ii) water, (iii) at least one of an oil and wax and (iv) a sorbitan fatty acid ester surfactant, wherein said emulsion also contains bubbles, said bubbles having been formed by adding a chemical foaming agent to the water-in-oil emulsion composition before or after the gelatinized nitromethane product and microsphere mixture is added to the water-in-oil emulsion composition.
