Description
Verfahren zur Vermeidung des Streuens von Abraum bei der Förderung von mit Trockenbaggern gewonnenem Gut über das anstehende Flöz im Tagebau Es hat sich als ein Nachteil der bestehenden Förderanlagen herausgestellt, daß namentlich an windigen Tagen und bei langer anhaltender Trockenheit das in Kübeln, auf Förderbändern o. dgl. über die anstehende Kohle geförderte Abraumgut über die Kohle gestreut wird, wenn es mit Trockenbaggern gewonnen ist, so daß die Kohle entweder vor ihrem Abbau gereinigt werden muß oder aber schlechte Briketts ergibt. Durch die vorliegende Erfindung wird in einfacher Weise eine Abhilfe geschaffen. Es wird durch sie ermöglicht, daß auch bei der Gewinnung mit Trokkenbaggern eine Förderung mit leichten Bändern stattfinden kann, welche an Seilen o. dgl. aufgehängt sind, ohne daß besondere Schutzkästen für die Bänder erforderlich werden; dabei läßt sich auch das Streuen aus den Kübeln vermindern.Method of avoiding the scattering of overburden during production of material extracted with dry excavators over the pending seam in the open-cast mine Es hat turned out to be a disadvantage of the existing conveyor systems that in particular on windy days and with prolonged drought that in buckets, on conveyor belts or the like. Overburden material conveyed over the pending coal is scattered over the coal, if it is extracted with dry excavators, so that the coal either before its mining has to be cleaned or it results in bad briquettes. Through the present The invention provides a remedy in a simple manner. It is made possible by them that even with the extraction with dry excavators a promotion with light belts can take place, which are suspended on ropes or the like, without special protective boxes for which tapes become necessary; You can also use the buckets for spreading Reduce.
Die Erfindung besteht darin, daß der mit Trockenbaggern, Kabelbaggern o. dgl. gewonnene Abraum' direkt bei der Gewinnung oder auf dem Bande oder im Kübel angefeuchtet wird,The invention consists in the fact that with dry excavators, cable excavators o. The like. Overburden 'obtained directly during the extraction or on the belt or in the bucket is moistened,
