Abstract

A filling material intended for underground mining is mixed together from a plurality of residue products and, by the addition of calcium chloride, is suitable primarily for pneumatic stowing. The filling material is mixed together from about 20% of washing and/or flotation wastes, 10% of wet gypsum from flue-gas desulphurisation plants, 70% of filter ash and binding water from flue-gas desulphurisation, the binding water containing more than 5% of calcium chloride.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

Bergeversatzstoff Es ist bekannt, daß Rückstandsprodukte aus der Verbrennung von Kohle in Kraftwerken, Wirbelbettfeuerungsanlagen und/oder sonstigen Industriekesseln, immer mehr Sorge bereiten. Bergeversatzstoff It is known that residue products from the Combustion of coal in power plants, fluidized bed combustion systems and / or others Industrial boilers, of increasing concern.

Das totale Nutzen der Stoffe ist in der Regel nicht mehr gewährleistet, da insbesondere auch der Schwarz deckenmarkt zurückgeht.The total use of the substances is usually no longer guaranteed, especially since the black cover market is also declining.

Um den Rückstand zu verbringen, sind vielfach Überlegungen angestellt worden, die Filterasche blastechnisch oder pumptechnisch im Untertagebergbau in die hohlgekohlten Räume einzubringen. Jedoch der Verschleiß sowohl in den Pumpen als auch in den Pumpenleitungen sowie auch in den Blasleitungen, ist erheblich.In order to get over the backlog, considerations are often made The filter ash has been blown or pumped in underground mining in to bring in the coal-fired spaces. However, the wear and tear in both the pumps as well as in the pump lines as well as in the blow lines, is considerable.

Um diesen Verschleiß auf ein Minimum zurückzuführen, wird erfindungsgemäß vorgeschlagen, Waschbere und/ oder Flotationsberge mit Filterasche zu mischen und pump- und/oder blastechnisch zu verbringen.In order to reduce this wear to a minimum, according to the invention proposed to mix washing and / or flotation mountains with filter ash and to spend pumping and / or blowing.

Zur besseren Bindung kann natürlich auch unbehandeltes Rückstandsprodukt aus der Rauchgasentschwefelung mit genutzt werden, wobei zur Staubbindung vorzugsweise auch Calciumchlorid mit dem REA-Gips, feucht enthalten als Bindewasser, zugeführt wird.Untreated residue product can of course also be used for better binding from the flue gas desulphurisation can also be used, preferably for dust binding Calcium chloride is also added to the FGD gypsum, which is contained moist as binding water will.

Zweckdienlicherweise wird ungefähr 20 % Waschberge, 10 % nasser REA-Gips und 70 % Feststoffe aus dem Bereich Filterasche als Gemenge zusammengebracht, wobei der Calciumchloridgehalt im REA-Wasser bei = größer 5 % liegt.Appropriately, about 20% wash mountains, 10% wet FGD gypsum and 70% solids from the filter ash area brought together as a batch, whereby the calcium chloride content in the FGD water is = greater than 5%.
