An explosive composition of the water-in-oil emulsion type includes at least one emulsified gel formed of an oxidizing solution of an inorganic salt dissolved in water and a fuel phase containing a liquid hydrocarbon and an emulsifier in combination with an inert or reactive lighting constituent and, if appropriate, one or more oxidizing salts or metal fuels. Pursuant to the invention the composition additionally contains from 4% to 55% of inert or semi-inert solids. The explosive composition provides enhanced safety characteristics through detonation velocity reduction and is thus well suited for dangerous atmospheres such as those encountered in coal mines. Additionally, the explosive composition exhibits a nonsticky plastic to semiplastic texture which facilitates cartridging on conventional machinery, all while retaining normal detonation characteristics.
