Abstract
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.
