Abstract
A dry water resistant ANFO-explosive, containing one or more organic fuels, one or more inorganic salts, one or more water thickening agents, and a gas generating substance which develops a gas when it gets in contact with water in a blast hole, and thereby transforms itself into a watergel slurry.
Claims6
A sensitized watergel slurry explosive made by the process of first forming a dry ANFO-explosive consisting essentially of one or more thickening agents, one or more inorganic oxidizer salts, one or more organic fuels, and a gas-generating substance;
- and then placing the dry ANFO-explosive in a bore hole that contains water, whereby the water dissolves part of the oxidizer salts, thickens the thickening agents and causes the gas-generating substance to generate a gas.
A method of forming a sensitized watergel slurry explosive in a water-containing bore hole consisting essentially of adding to the bore hole a dry ANFO-explosive comprising one or more inorganic oxidizer salts, one or more organic fuels, one or more thickening agents and a gas-generating substance whereby the water in the bore hole dissolves part of the oxidizer salts, thickens the thickening agents and causes the gas-generating substance to generate a gas.
