Abstract

A method of excavating limestone (marl) is proposed, the limestone (marl) being produced in one operation directly during the winning. A bucket-wheel excavator is used for the winning.

Description

Die Erfindung betrifft ein Verfahren zum Abbau von Kalkstein (Mergel).The invention relates to a method for mining limestone (marl).

Zur Gewinnung von Kalkstein ist folgendes Verfahren von praktischer Bedeutung: Bohren, Sprengen, Gewinnen mit dem Löffelbagger, Laden auf LKW oder Bahn, Transport, Brechen des wesentlichen Kalksteinanteiles sowie Weitertransport auf Bandanlagen.The following method is more practical for extracting limestone Meaning: drilling, blasting, mining with a backhoe, loading onto a truck or rail, transport, crushing the essential limestone portion as well Further transport on conveyor systems.

Durch die Vielzahl der durchzuführenden Arbeitsschritte von der Gewinnung bis zum Bandtransport entstehen nicht nur große Verzögerungen, sondern auch relativ geringe Durchsatzleistungen bei hohen Material- und Personalkosten. Diese Arbeiten sind notwendig, da der Kalkstein beim Sprengen sehr grobstückig verbleibt und nahezu vollständig erst über einen Brecher geführt werden muß, ehe das Material bandtransportfähig ist.Due to the large number of work steps to be carried out from extraction There are not only major delays until the tape is transported, but also relatively low throughput rates with high material and personnel costs. This work is necessary because the limestone is very blasting remains in large pieces and almost completely passed over a crusher must be before the material is ready for belt transport.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu konzipieren, welches diesen Nachteil beseitigt.The invention has for its object to design a method which eliminates this disadvantage.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kalkstein (Mergel) in feinstückiger, im wesentlichen bandtransportierfähiger Korngröße in einem Arbeitsgang unmittelbar bei der Gewinnung erzeugt wird.This object is achieved in that the limestone (Marl) in fine-grained, essentially belt-transportable grain size is produced in one operation immediately during extraction.

Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sind den Unteransprüchen zu entnehmen.Advantageous developments of the method according to the invention are the See subclaims.

Als bevorzugtes Gerät zur kontinuierlichen feinstückigen Gewinnung von Kalkstein (Mergel) soll ein Schaufelradbagger zur Anwendung kommen.As the preferred device for the continuous fine extraction of Limestone (marl) is to be used in a bucket wheel excavator.

Im Gegensatz zum Stand der Technik werden folgende Vorteile erzielt:In contrast to the prior art, the following advantages are achieved:

  • - Feinstückigkeit wird bereits beim Gewinnen erzeugt, d.h. anstelle der bekannten drei Prozeßstufen (Sprengen, Laden, Brechen) ist nunmehr nur noch eine notwendig.- Precision is already generated when winning, i.e. instead of known three process stages (blasting, loading, breaking) is now only one more necessary.
  • - Der Brecher hat nur noch eine Sicherheitsfunktion, um Überkorn zu verhindern, d.h. die Brecheranlage kann kleiner ausgelegt werden, da nur noch etwa 10% Überkorn vorhanden ist. - The crusher only has a safety function to prevent oversize particles prevent, i.e. the crusher plant can be designed smaller because only about 10% oversize is left.  
  • - Der Feuchtigkeitsanteil des Materials nach dem neuen Verfahren ist geringer, da das Material sofort nach der Gewinnung abgeführt wird und nicht, wie beim herkömmlichen Verfahren, nach dem Sprengen am Böschungsfuß liegenbleibt und so Witterungseinflüssen ausgesetzt wird.- The moisture content of the material is according to the new process less because the material is removed immediately after extraction and not, as with the conventional method, after blasting on Embankment foot remains and is exposed to weather influences.
  • - Reduzierung der Personal- und Materialkosten.- Reduction of personnel and material costs.
