    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.
