Abstract
Disclosed herein is an explosive composition for soft and wet ground. The explosive composition comprises an explosive comprising an oxidiser component in a water in oil emulsion or a water gel, and a bulking agent comprising discrete particles of a combustible substance. The combustible substance is water soluble but, in the explosive composition, migration of the combustible substance from the discrete particles to the oxidiser component is inhibited. Also disclosed is a method for delivering an explosive composition to a borehole, for example a borehole in soft and wet ground.
