ABSTRACT:
Provided herewith is a method for preparing an explosive composition with an adjusted rate of detonation which matches the rock stratum in which blasting is to occur. The composition is comprised of a mixture of glass microballoons and plastic spheres, which mixture has been found to provide one with adjustable rates of detonation with essentially no significant difference in the carbon, hydrogen, oxygen, nitrogen and water contents or ratios and at the same time with the same overall energy.
