A blasting composition comprising a mixture of inorganic nitrate, e.g., ammonium nitrate, and a high density hydrocarbon liquid has substantially more explosive force than an equal volumetric amount of a mixture of ammonium nitrate and diesel fuel. The latter is a commercial explosive currently used in large quantities. A high density hydrocarbon liquid is one having a density >/= 0.910; net heating value >/= 135,000 BTU/gal., and a pour point </= -30 DEG F. Examples of such hydrocarbons include exo-tetrahydrodicyclopentadiene or a mixture of C14H18 hexacyclic dimers of norbornadiene. Also disclosed is an improved method of blasting.
