In Britain in 1912 and 1913, a rash of mine explosions lead to a formal court inquiry. It was found that at this time the practice of signaling was accomplished by the rubbing together of two bare wires connected to a battery to form a circuit. As a result of the court findings, testing became required for signaling equipment in British mines. [Pg.255]

Owing to their intrinsic safety and inexpensive nature, AN/fuel formulations have almost completely replaced dynamites as the mining explosive. As a result, they are by far the most widely used explosive. AN formulations are sold as AN prill or solution, ANFO pre-mixed, AN water—gel (although this is becoming obsolete) AN emulsions, either in cartridges or as bulk material that is brought to the site and loaded directly from the tmck to the borehole and heavy ANFO (ANFO folded into an AN emulsion). AN formulations usually require the use of a high explosive booster, but powerful and cap-sensitive formulations can be prepared. [Pg.19]

Another Commission was appointed in France to inquire into coal-mine explosions. Influenced by Berthelot s work and theories, its attention was directed to the question of the heat evolved by an explosive and the resulting temperature of the products (Ref 11, p 45) Note I As a result of the work of the Commission, a max temp of 1500°C for expls used in coal layers (explosifs grisou-couche) was established and 1900°C for expls used for blasting rock in gaseous coal mines (explosifs grisou-roche) (Vol 3 of Encycl, p C369-L)...
