Abstract

In a method of filling aquiferous boreholes with a powdered ammonium nitrate explosive containing swelling and water-repellentizing agents which is uncartridged by means of a gaseous propellant from a pressure tank through a conduit, the improvement which comprises feeding said explosive composition to said aquiferous borehole through an orifice positioned toward the bottom of the borehole and thereafter step-wise or continuously withdrawing from the bottom such orifice from such conduit such that the orifice is located no more than 50 cm above the surface of the delivered explosive and below the surface of the water in the borehole.
