Abstract
A gas-retaining agent consisting of bubble assemblies, each bubble assembly being one particle consisting of a large number of bubbles agglomerated into the particle, is effective for improving the safety of water-in-oil emulsion explosive compositions against methane and coal dust, for improving the sympathetic detonability of the explosive compositions and for lowering their detonation velocity without deteriorating their strength.
