Tomic, E A

The present invention provides an explosive composition, e.g., a blasting agent in the form of an emulsion consisting of inorganic oxidizing salt, water, water-insoluble carbonaceous fuel, and sensitizer. The improvement is that the composition contains an ammonium or alkali metal stearate salt to form the emulsion. The water-bearing inorganic oxidizing salt and carbonaceous fuel containing the stearate salt form a stable emulsion due to the presence of the salt. The stearate salt that causes the emulsion to be formed imparts to the composition properties and characteristics not possessed by other compositions, e.g., blasting agents containing an emulsifying agent. First, the water resistance of compositions emulsified with the stearate salts is substantially higher than those emulsified with other emulsifying agents. Second, the stearate salt emulsified composition is readily pumpable, and, third, it does not adhere to walls of containers in which it can be packaged prior to use.
