    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： A blasting explosive composition containing a solid inorganic oxidising salt as the oxidizer component, a hydrocarbon liquid as the fuel component, and a binding agent. The composition can also contain an ammonium nitrate based emulsion. The binding agent can increase the water resistance, or increase the sleep time, of the explosive composition, or increase the fuel oil absorbency of the solid inorganic oxidising salt. The binding agent is selected from one or more of a long chain carboxylic acid and its salts and derivatives, especially those having from 8 to 100 or preferably 10 to 50 carbon units. The binding agent may preferably be selected from one or more of: dimer acid, trimer acid, polyisobutylene succinic anhydride, oleic acid, stearic acid, sorbitan tristearate, and their salts and esters.

    摘要： The present disclosure describes systems and methods for delivering a primer to an operative depth for initiating an explosion of an explosive material in a blasthole. Systems described herein can include a cap structure providing access into the hole and a separable detonator subassembly that can be deployed to convey a detonator to a priming position. Methods of priming a blasthole can include placing such a system on a blasthole collar and deploying the detonator subassembly in conjunction with loading the blasthole with explosive material.

    摘要： An end of hose mixing system for development charging may include a static mixer disposed near the end of a delivery apparatus. The mixing system may include a mixing tube with a central bore, and the mixing tube is coupled to an outlet of a delivery hose. The mixing tube includes a static mixer disposed within the central bore of the mixing tube. The spray nozzle system further includes a nozzle with a central bore, and the nozzle is coupled to the mixing tube outlet. The static mixer may be disposed within a delivery hose itself. The static mixer may be disposed a predetermined distance from a distal end of the delivery apparatus to establish laminar flow of an emulsion after the emulsion is mixed with a sensitizing agent by the static mixer. The sensitized emulsion may be expelled from the delivery apparatus at an angle less than 45 degrees.

    摘要： Systems for delivering explosives including homogenizing agents and methods of delivering explosives including homogenizing agents are provided. Methods of mixing homogenizing agents with emulsion matrices are also provided. The methods can include supplying an emulsion matrix, mixing a homogenizing agent with the emulsion matrix into a mixed product, and homogenizing the mixed product into a homogenized product. The homogenized product can be sensitized and/or conveyed to a blasthole.
