Abstract
This invention provides an explosive composition comprising a blend of a melt-in-fuel emulsion and solid particulate oxygen-releasing salt. Said melt-in-fuel emulsion comprises a discontinuous oxygen-releasing salt phase, a continuous water-immiscible organic fuel phase and an emulsifier component. The oxygen-releasing salt is preferably selected such that the water content is minimized. The explosive composition may additionally comprise a discontinuous gaseous component. The compositions are stable against crystallization and segregation and are blowloadable without significant blowback. The compositions have an added advantage of a propensity to be loaded into upholes without the need for stemming or other plugging arrangements.
