Abstract
An explosive composition comprising an explosive mixture of ammonium nitrate and fuel oil. The fuel oil is selected to provide an oil separation sufficiently low so that the explosive is detonatable. The fuel oil is also selected such that the viscosity of the explosive is sufficiently low so that the explosive may be loadable into a borehole. The explosive is substantially free of tackifying agents.
Claims56
A storage stable explosive composition which may contain recognized additives for explosives consisting essentially of an explosive mixture of low adsorption ammonium nitrate particles and fuel oil, said fuel oil having viscosity sufficient to render the explosive composition detonatable and sufficient to render the composition loadable into a borehole.
A storage stable explosive composition which may contain recognized additives for explosives consisting essentially of an explosive mixture of low adsorption ammonium nitrate particles and fuel oil, said fuel oil having viscosity sufficient to render the explosive composition detonatable and sufficient to render the composition loadable into a borehole said explosive composition being essentially free of tackifying agents.
A method for producing a storage stable explosive composition which may contain recognized additives for explosives consisting essentially of an explosive mixture of low absorbtion ammonium nitrate particles and fuel oil comprising the steps of:
- (a) selecting a fuel oil having viscosity sufficient to render the storage stable explosive composition detonatable and sufficient to render the storage stable explosive composition loadable into a borehole;
- (b) combining said fuel oil with a sufficient amount of low absorbtion ammonium nitrate particles to render the explosive composition essentially oxygen-balanced;
- and,
- (c) mixing said ammonium nitrate with said fuel oil.
