Abstract From the Canadian patent
Abstract, An emulsion explosive composition comprising a discontinuous phase containing an oxygen-supplying component and an organic medium forming a continuous phase wherein the oxygen-supplying component and organic medium are capable of forming an emulsion which in the, absence of a supplementary adjuvant exhibits an, electrical conductivity measured at 60°C not exceeding, 60,000 picomhos/metre. Such conductivity may be achieved by inclusion of a modifier. The compositions exhibit improved storage characteristics.
