Abstract
The invention relates to emulsified aqueous explosive blasting compositions having a discontinuous aqueous phase, a continuous oil or water-immiscible liquid organic phase, and a fatty acid amine or ammonium salt emulsifier having a chain length ranging from 14 to 22 carbon atoms.
Claims15
In an inverted phase aqueous blasting composition having a water-immiscible liquid organic fuel as a continuous phase, an emulsified aqueous inorganic oxidizer salt solution as a discontinuous phase, and an emulsifier;
- the improvement comprising, as the emulsifier, from about 0.5% to about 5.0% by weight, based on the total composition, of a fatty acid amine or ammonium salt having a chain length ranging from 14 to 22 carbon atoms.
An inverted phase aqueous blasting composition comprising a water immiscible liquid organic fuel as a continuous phase in an amount of from about 1% to about 10% by weight based on the total composition;
- and emulsified aqueous inorganic oxidizer salt solution comprising water in an amount of from about 5% to about 20% and inorganic oxidizer salt in an amount of from about 60% to about 94%;
- and, as an emulsifier, a fatty acid amine or ammonium salt having a chain length ranging from 14 to 22 carbon atoms and in an amount of from about 0.5% to about 5.0%.
A method of formulating an inverted phase aqueous blasting composition comprising a water-immiscible liquid organic fuel as a continuous phase, an emulsified aqueous inorganic oxidizer salt solution as a discontinuous phase, and from about 0.5% to about 5.0% by weight, based on the total composition, of a fatty acid amine or ammonium salt emulsifier having a chain length ranging from 14 to 22 carbon atoms;
- which method includes the steps of predissolving the emulsifier in the liquid organic fuel prior to adding these components to the salt solution, and mixing or stirring the components to form the inverted phase emulsion.
