Founded on May 16, 1910, through the Organic Act (Public Law 179), USBM's missions ...
An explosive containing ammonium nitrate sensitized with trinitrotoluene. A proportion of aluminum powder or calcium silicide may be added to increase power and sensitiveness.
Industry:Mining
An explosive containing still smaller quantities of liquid products, compared with plastic and semiplastic explosives, so that the spaces between the solid particles are not filled out entirely. As the result of this, the density of the mass is 20% to 40% lower than that of plastic and semiplastic explosives.
Industry:Mining
An explosive containing the liquid ingredients named, in contradistinction to dynamite, which contains nitroglycerin. In commerce, the term dynamite is loosely used to include any mixture containing a liquid explosive.
Industry:Mining
An explosive containing, principally, nitroglycerin, nitrocotton, and inorganic nitrates, with a suitable combustible absorbent giving a balanced composition.
Industry:Mining
An explosive in which the change into the gaseous state is effected by burning and not by detonation as with high explosives. Blasting powder (black powder or gunpowder) is the only low explosive in common use. It requires no detonator but is ignited by means of a safety fuse.

Industry:Mining
An explosive material that meets prescribed criteria for insensitivity to initiation. It is a material or mixture consisting of fuel and oxidizer used in blasting, but not otherwise defined as an explosive. The finished mixture used for shipment or transportation cannot be detonated by a No. 8 test detonator cap when unconfined.
Industry:Mining
An explosive mixture consisting of about 80 lb (36.5 kg) of ammonium nitrate mixed with 10 pints (4.7 L) of molasses and 5 pints (2.37 L) of water, for quarry and opencast blasting. The molasses and water may be used instead of fuel oil and give a denser mixture with improved fragmentation.
Industry:Mining
An explosive mixture consisting of ammonium nitrate and carbonate, liquid and solid hydrocarbons, and zinc chlorate.
Industry:Mining
An explosive of special character used in small quantities to improve the performance of another explosive, the latter forming the major portion of the charge.
