Abstract
A blasting composition, method and system for making such is disclosed. The blasting composition is a homogeneous slurry-type blasting agent containing a major amount of water and a relatively small amount of a particulate fuel, preferably a particulate metal fuel. The blasting composition is made by premixing the fuel with water and a gelling agent to form a stable suspension of fuel in the water, metering the suspension of fuel into a dry particulate mixture of an inorganic metal oxidizer and a gelling agent, and slowly tumbling the mixture a short time sufficient to obtain a uniform composition without desensitizing the composition to detonation.
