Mine, poudres

Mine, Poudres de. BkPdrs manufd in Fr beginning in 1900 for use in mines. Their shape was either angular or round, and they were divided into three classes strong (forte), ordinary (ordinaire) and slow (lente). K nitrate content ranged from 72.62% for forte to 40% for lente . A special lente pdr contd K nitrate 65, sulfur 15, charcoal 10 and sawdust 10%... [Pg.151]

The same explosives were formerly employed in Russia, where the mining explosives industry was financed by French capital. In both countries Favier Powders (Poudres Favier) or Favier explosives (Explosifs Favier) were also employed. Their composition is tabulated below. [Pg.403]

Common blackpowder or improved poudre H is also used in Belgium in opencast mines. The latter contains a certain amount of ammonium nitrate and is used only in mines when large charges of explosives are used. It is initiated exclusively by a detonating fuse. [Pg.448]

Since none of the above listed "antifreezes was really good, many. industrialists preferred not to use them at all, but just defrost the ordinary Dynamite in winter or store it in a warm magazine. This situation lasted until 1902 when a severe exp In in Greisenau Mine, Germany, was caused by frozen Dynamite. This disaster produced the renewal of research on antifreezes and in 1903 the SA de Poudres et Dynamites of France introduced DNT TNT as antifreezes. These compds did not reduce appreciably the strength of Dynamites and were satisfactory from this point of view. They, however, did not lower the ft p of NG sufficiently for use in very cold weather... [Pg.483]

Commission Francois du Grisou (French Commission for Firedamp). In order to study the problems in connection with the use of expls in gaseous coal mines, a special Commission was established in 1877 as a branch of the Service des Poudres et Salpetres. Its first president was E. Mallard. The work of this Commission is briefly discussed under COAL MINING EXPLOSIVES AND SOME OTHER COMMERCIAL EXPLOSIVES and in Refs 1 2 Refs 1)CSE, "L Emploi des Explosifs en Presence du Grisou , MP 2, 355-41 (1884-89) 2)CSE, Supplementary Rept on the same subject, MP 2, 466-572 (1884-89)...
