Abstract
The invention relates to cap-sensitive water-in-oil emulsion blasting agents having a discontinuous aqueous phase, a continuous oil or water-immiscible liquid organic phase, an emulsifier, and perlite of fine particle size.
Claims11
A cap-sensitive water-in-oil emulsion blasting composition comprising a water-immiscible liquid organic fuel as a continuous phase, an emulsified aqueous inorganic oxidizer salt solution as a discontinuous phase, an emulsifier, and perlite in an amount of from about 1.0% to about 8% by weight based on the total composition having an average particle size ranging from about 100 microns to about 150 microns as a sensitizing agent and a density reducing agent in amount sufficient to reduce the density of the composition to within the range of from about 0.9 to about 1.4 g/cc and to render the composition cap-sensitive.
A cap-sensitive water-in-oil emulsion 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;
- an emulsified aqueous inorganic oxidizer salt solution comprising water in an amount from about 5% to about 20% and inorganic oxidizer salt in an amount from about 60% to about 94%;
- an emulsifier in an amount from about 0.2% to about 5.0%, and perlite having an average particle size ranging from about 100 microns to about 120 microns in an amount of from about 1% to about 8%.
