A blasting agent utilizes ammonium nitrate fuel and water to form a desired plasticity. The compound is detonatable because it employs fuel which is water stable either chemically or physically or both and remains in intimate association with the ammonium nitrate in the presence of water whether in the solid phase or liquid phase. The total oxygen balance of ammonium nitrate and fuel is adjusted by the formula proportions to be within detonatable limits. The method for making the blasting agent utilizes heat to liquefy a normally solid fuel while mixing with porous prilled ammonium nitrate to effect adsorption and absorption of the fuel by the ammonium nitrate. This effects intimate association in the solid phase and liberates only that portion of fuel into the liquid phase which corresponds to the quantity of ammonium nitrate which is dissolved by the added water.
