摘要： A water resistant explosive composition is disclosed for use in wet blasting holes. The composition comprises ammonium nitrate prills coated with a glycol and oil emulsion to render the prills waterproof. The coated prills are mixed with quick hydrating and self-complexing guar gums. The compositions can be poured directly into water filled blasting holes. The guar gums in the presence of cross-linking agent form a gel in the bore hole to lend stability to the composition until exploded. The composition has excellent shooting properties.

摘要： Method and apparatus for making aqueous slurry explosives are disclosed. The components of the aqueous slurry explosive are mixed in a variable speed rotary mixer where the speed of the mixer is determined by the sequence of addition of the explosive components. The explosive components generally comprise water; an inorganic oxidizing salt such as ammonium nitrate; organic liquid such as propylene glycol; organic solids such as sugar; air entraining agents such as microspheres; densifying agents such as hot ammonium nitrate solutions; thickening agents such as flours and guar gums and pH adjustors and self-explosives. The aqueous slurry explosive may be formed using ambient temperature water. The apparatus is particularly suited as a mobile unit for use in the field.
