System for making an aqueous slurry-type blasting composition

摘要

A blasting composition, method, and system for making such is disclosed. The blasting composition consists essentially of a particulate inorganic nitrate oxidizer, a particulate metal fuel, water, and a gelling agent. The composition is prepared by blending 10-20% by weight of the total amount of water to be added to the composition, with the particulate inorganic nitrate oxidizer; adding a dry blend of gelling agent and particulate metal fuel to the damp oxidizer; briefly mixing the two components; adding the remainder of the water; and slowly subjecting the mixture to a tumbling action for a brief period of time sufficient to obtain a uniform composition.
