The present invention relates to a method of reducing the energy of an emulsion blasting agent as it is being loaded into a borehole and to an improved method of perimeter blasting wherein an energy reducing agent is added to and mixed uniformly throughout an emulsion blasting agent as it is being pumped or conveyed into a perimeter borehole to reduce the energy of the blasting agent to a desired level. In addition, by adding varying amount of gassing agents, the density and sensitivity of the emulsion blasting agent also can be controlled.
What is claimed is: 1. A method of reducing the energy of an emulsion blasting agent as it is being loaded into a borehole comprising the steps of: a) selecting an emulsion blasting agent comprising an aqueous inorganic oxidizer salt solution forming in droplet form a discontinuous phase and an organic liquid fuel forming a continuous phase; b) conveying the emulsion blasting agent; c) adding an energy-reducing agent to the emulsion blasting agent as it is being conveyed wherein the energy reducing agent is selected from the group consisting of water an...
