ABSTRACT:
A matrix material to be added to a standard ammonium nitrate-fuel oil dry explosive to form an economical slurry explosive having excellent water resistant properties includes an oxidizer solution chosen from the group of an aqueous sodium perchlorate solution, an aqueous ammonium perchlorate solution, an aqueous calcium nitrate solution, or a combination thereof, along with a fuel such as ethylene glycol or fuel oil and a thickening agent such as a guar gum in combination with an acid such as glacial acetic acid. The oxidizer solution generally makes up about 94%-97% by weight of the matrix. The slurry explosive is made by mixing the matrix with a standard ammonium nitrate-fuel oil dry explosive and then adding a cross linker to the mixture so that it forms a gel. The matrix may make up between about 14% to 40% by weight of the explosive, and preferably makes up about 20% by weight.
