A pumpable watergel explosive composition comprises 10 to 40 wt %, base d on the total weight of the pumpable explosive composition, of a continuous liquid phase comprising a solvent, a solubilized chemical sensitizer and a gelling agent and 60 to 90 wt %, based on the total weight of the pumpable explosive composition, of a discontinuous solid phase comprising particulate oxidizer salt particles having interstitial spaces between the salt particle s. The watergel explosive composition has a density of 1.05 - 1.4 g/cc and, a shear thinning rheology such that, when subjected to an external force, the explosive composition has a viscosity sufficiently low to render the waterge l explosive composition pumpable. The combination of density and low water content provides energy numbers normally associated with more expensive aluminized formulations.
