A dry non-explosive additive for ammonium nitrate-fuel oil (ANFO) blasting agents which provides water resistance and wet sensitivity to allow use of the explosive in wet drill holes. The additive contains gelling agents that rapidly hydrate and swell upon water impingement, and thereafter cross-link to rapidly form a peripheral water-blocking barrier to prevent further water intrusion into a loaded blasting agent mass. The additive additionally contains hydrophobic sensitizers and optional fuels to provide points of adiabatic compression and physically ...
A dry, non-explosive particulated additive for an ammonium nitrate and fuel oil explosive composition, to allow use of such composition in wet environs, comprising in combination, by dry weight portion of the additive composition: Particulated dry gelling agent: 5-90%, cross-linking agent: 0.025-9%, energy and sensitivity additives: 10-90%, particulated solid carbonaceous fuels: 0-25%, inert hydrophobic solids: 0-10%.
