Abstract: Disclosed herein is an explosive composition for soft and wet ground. The explosive composition comprises an explosive comprising an oxidiser component in a water in oil emulsion or a water gel, and a bulking agent comprising discrete particles of a combustible substance. The combustible substance is water soluble but, in the explosive composition, migration of the combustible substance from the discrete particles to the oxidiser component is inhibited. Also disclosed is a method for delivering an explosive composition to a borehole, for example a borehole in soft and wet ground.

Abstract: The present invention relates generally to an explosive composition comprising an aqueous emulsion of: an oxidizer component, a hydrocarbon fuel component containing emulsifier, and a bulking agent being a fuel-type waste material in a solid particulate form substantially lacking rough surfaces and sharp edges. Preferably the composition is of an ammonium nitrate based emulsion and a pelletised bulking agent. It also involves a method of providing an explosive composition to a blast site using a conventional mobile processing unit (MPU), being a truck having separate compartments adapted for holding fuel oil, dry ammonium nitrate prill, and ammonium nitrate based emulsion, where a compartment instead holds particulate waste material. It also concerns a method of blasting soft and wet ground, which comprises injecting into one or more blast holes in the soft and wet ground a sufficient quantity of the composition, and then setting off the composition.
