Abstract
A detonator sensitive, stable water-in-oil or melt-in-oil
emulsion explosive comprises an oxidiser containing
discontinuous phase, a fuel containing continuous phase, and
an emulsifier. To increase the safety of the explosive in
flammable atmospheres, such as in coal mines, from 7% to 15%
w/w of at least one of the following cooling agents is
dissolved in the discontnuous phase: sulphonate, phosphonate,
ammonium halide, alkali metal halide, alkaline earth metal
halide, or a soluble phosphate salt. Preferably at least 20%
of cooling agent is distributed between the continuous and
discontinuous phases, with at least about 7% preferably about
12% present in the discontinuous phase.
