    摘要： 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.

    摘要： The present invention relates to a water-based non-sensitized matrix or explosive suspension which itself has a rheological behavior such that it allows mechanically loading upward boreholes. This suspension behaves like a viscous liquid when it is forced to flow due to the action of a loading pump, and, however, has the characteristics of a soft solid when it is on standby once inside the borehole. The composition essentially consists of an aqueous solution of oxidizing salts and optionally water-soluble fuels and/or sensitizers, and one or more water-soluble polymers conferring the desired rheological characteristics. Particles of oxidizing salts with a grain size such that they enhance the rheological behavior characteristic of the suspension are dispersed in this aqueous solution.

    摘要： Manufacture is carried out in a continuous manner while simultaneously loading the blast holes in a device with mixing capability where (a) a less sensitive or non-explosive water-based matrix containing a cross-linkable polymer, (b) a cross-linking agent for cross-linking the polymer contained in the matrix, (c) a gas-generating agent, are mixed. The presence of the polymer distributed uniformly in the matrix together with the cross-linking agent results in a three-dimensional network formed by molecular polymer chains bound to one another in a short period of time after mixing. The process can be performed in trucks for loading explosives in blast holes having compartments for the different components of the mixture and one or several mixing devices allowing the manufacture of the final mixture which would be unloaded into the blast holes either by means of a pump or an auger.

    摘要： A gas propelled munitions anti-fouling system has a case having an open forward mouth end, a rear end, and an interior, the rear end defining a pocket that receives a primer and a passage communicating between the pocket and the interior of the case, a quantity of propellant received within the interior of the case, a quantity of anti-fouling composition received within the interior of the case, and a bullet having a rear portion inserted into the open forward mouth end of the case. The anti-fouling composition may have at least one salt and at least one acid. The acid may be anhydrous. The salt may be sodium chloride or sodium nitrate. The acid may be anhydrous citric acid. The anti-fouling composition may have at least one abrasive. The abrasive may be stannic acid. The anti-fouling composition may be 50% salt by weight and 50% acid by weight.

    摘要： Compositions, methods and systems involving nitrate compounds are disclosed and described. A method of dissolving a nitrate compound having an additive can comprise dissolving the nitrate compound to form an aqueous nitrate solution and adding a surfactant to the aqueous nitrate solution, where the surfactant disperses the additive.
