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 subjectin...
A method for making a homogeneous, aqueous slurry-type blasting composition containing a particulate inorganic nitrate oxidizer and a particulate metal fuel, comprising: blending a particulate gelling agent together with a finely divided powdered metal to form a dry mixture thereof; blending 10-20% by weight of the total amount of water to be used in the composition with the particulate inorganic nitrate oxidizer; adding the dry blend of gelling agent and powdered metal to the damp, particulate, inorganic nitrate oxidizer; blending the damp inorganic oxi...
