Description
Versatz- und Fördermatte Im Bergbau verwendet man zur Begrenzung des Berges toß es gegenüber dem Kohlenstoß insbesondere in der halbsteilen und steilen Lagerung vielfach Matten aus Federstahlgeflecht, Gummi oder Kunststoff. Diese Matten werden zur Erhöhung der Elastizität mit federnden Armierungen versehen. Durch das ständige Aufprallen, insbesondere dann, wenn die Trennwand gleichzeitig als Fördermatte benutzt wird, wird der im Mattenkörper befindliche Federstahlträger schnell ermüden, so daß diese Matten nach der Ermüdung nicht mehr vollwertig den Zweck einer Abdichtung vom Liegenden zum Hangenden gegenüber dem Berge- und Kohlenstoß gewährleisten, sondern sich nach der Ermüdung des Federstahls plastisch verformen und Kohlenverluste bei der Förderung auf der Matte während der Gewinnung unvermeidbar sind.Offset and conveyor mat In mining, one uses to limit the Berges, it rushed against the coal face, especially in the half-steep and steep one Storage often made of spring steel mesh, rubber or plastic. These mats are provided with resilient reinforcements to increase elasticity. By the constant impacts, especially when the partition wall doubles as a conveyor mat is used, the spring steel support in the mat body will tire quickly, so that these mats no longer fully serve the purpose of a seal after fatigue ensure from the lying to the hanging wall opposite the mountain and coal rush, but plastically deform after fatigue of the spring steel and carbon losses the promotion on the mat during the extraction are unavoidable.
Um eine immer dicht bleibende Trennung mittels - Matte zwischen Berge- und Kohlenstoß zu gewährleisten, wird der elastische, mit Armierungen versehene Kunststoffkörper oder Gummikörper, der als Versatzmatte und gleichzeitig als Kohlenabfuhrmatte benutzt werden kann, erfindungsgemäß mit ein- oder aufgearbeiteten Taschen versehen, in denen man die federnden Armierungen, wie Federstahlgeflecht, Federbandstahlstreifen od. dgl. einsetzen kann. Diese Anordnung der Taschen hat den großen Vorteil, daß man ermüdete Elastizitätsmomente, wie Federbandstahlstreifen od. dgl., während des Betriebes ausbauen und durch neue ersetzen kann, so daß die Matte in jedem Fall eine Dichtwirkung zwischen Kohle- und Bergestoß gewährleistet. In order to keep a tight separation by means of a mat between mountains and to ensure coal impact, the elastic, reinforced one is provided Plastic body or rubber body, which is used as an offset mat and at the same time as a coal removal mat can be used, provided according to the invention with incorporated or reconditioned pockets, in which you have the resilient reinforcements, such as spring steel mesh, spring steel strips or the like. Can use. This arrangement of the pockets has the great advantage that you tired moments of elasticity, such as spring steel strips od. Like., During the Can expand and replace with new ones, so that the mat in in any case one Sealing effect between coal and mountain impact guaranteed.
