Improved system for pumping slurry of gel explosives into boreholes

Abstract

A method is described for injecting an explosive slurry into a borehole containing water. The slurry is heavier than water and is pumped through the tubing to a depth close to the bottom of the well. Injection is continued until all water has been displaced above the lower end of the tubing. This type of immiscible displacement results in substantially no mixing between the water and the explosive. (15 claims)
