Um elektrische Zünder herzustellen, die bei der DieL.,onation keine Zündung von empfindlichcn Methan-Luft-Gemis#chen verursachen, bat man die Ladung der üblichen Sprengkapseln verändert (Patent 8o3 645). Ein anderer Weg zur Erziielung schlagwettersicherjer elektrischer Zünder besteht darii, n, daß man an Stelle der üblichen Zündpülen. solche benutzt, die selbst keine empfindnehlen Methan,-Luft-Gemische zünden können. D-*ie Dietonationsleit der Sprengkapsel ist in der Regel se kurz, daß s-e zur Schlagwerterzündung nicht ausreicht.Firedamp-proof electric detonators The use of non-firedamp-proof electric detonators in coal mining leads to km-m of firedamp explosions. hahen. In order to produce electric detonators which would not cause the ignition of sensitive methane-air mixtures during dieL. Another way of producing firedamp-proof electric detonators is to use instead of the usual detonators. uses those that cannot ignite any methane or air mixtures themselves. The detonation line of the detonator capsule is usually short so that it is not sufficient to ignite the impact value.
