Abstract

The invention relates to an emulsion explosive composition comprising a discontinuous phase comprising at least one oxygen-releasing salt; a continuous organic phase; an emulsifying agent; and at least one polymer soluble in the organic phase and wherein the polymer comprises associative functional groups.
The explosive is especially advantageous for use in wet boreholes.
