Abstract

Areas exposed during the open cast mining, e.g. of salt and potash, are returned to an acceptable form by back filling with a mixture of the unusable spoil and industrial waste. The industrial waste is processed in a milling operation to produce a particle form that readily mixes with the mining waste. The combined mixture is subjected to compaction to project against ground subsidence. USE/ADVANTAGE - Use of industrial waste, e.g. from electronics industry. Returning open areas to original form.

Description

Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Anspruchs 1. Es ist bekannt daß die Abraumhalden im Bereich der Kali­ bergwerke nicht gern gesehen werden.The invention relates to a method according to the preamble of claim 1. It is known that the tailings piles in the area of the potash mines are not welcome.

Andererseits gibt es unverbringbare Reststoffe, bestehend aus verunreinigten Kunststoffen und Anlagerungen von Metallfolien, Restfraktionen aus der Aufbereitung von Elektronikschrott und aus anderen industriellen Aufbereitungsanlagen.On the other hand, there are irreplaceable residues consisting of contaminated plastics and deposits of metal foils, Residual fractions from the processing of electronic waste and from other industrial processing plants.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Verfahren zur Verfügung zu stellen, mittels dem die Aufhaldung im Kali­ bergbau reduziert und unverbringbare Reststoffe entsorgt werden können.The invention has for its object to provide a generic method for To be made available by means of the pile in the potash Mining reduced and disposable residues disposed of can be.

Diese Aufgabe löst die Erfindung durch ein Verfahren mit den Merkmalen des Anspruchs 1. The invention solves this problem with a method the features of claim 1.

Erfindungsgemäß wird daher vorgeschlagen, die Hohlräume im Bergwerksbereich Kali und Salz wirtschaftlich zu versetzen, indem man die bisherigen Industrierückstände, bevorzugt Kunst­ stoff und deren Begleitfolien an anlagernden Stoffe aus der Elektroindustrie, mit neutralisierenden Abraumsalzrückstän­ den so vermischt, daß sie eine gleichmäßige Verbindung ein­ gehen und in den zwangsläufig geschaffenen Hohlraum ver­ setzt werden können. According to the invention it is therefore proposed that the cavities in the To economically move the potash and salt mining area, by looking at the previous industrial residues, preferably art fabric and its accompanying foils on attached materials from the Electrical industry, with neutralizing overburden salt residues which is mixed so that it creates a uniform connection go and ver into the inevitably created cavity can be set.  

Verfahrensmäßig wird also erfindungsgemäß vorgeschlagen, die­ se genannten Rückstände aus der Salzaufbereitung mit den oben genannten Reststoffen aus industriellen Aufbereitungsanlagen so zu vermischen, daß sie über eine Schleuderversatztechnik als Füllversatz angeschleudert werden können und somit als neutrale stützende Pfeiler befahrbar sind, indem sie schei­ benweise von unten nach oben bis zum Hangenden eingebracht werden.In terms of the method, the invention therefore proposes that residues from the salt treatment with the above mentioned residues from industrial processing plants to mix so that it uses a centrifugal offset technique can be flung as a filling offset and thus as neutral supporting pillars are passable by shitting introduced from the bottom up to the slope will.

Diese Pfeiler werden je nach Grubenfreiraum bis zu 40 m hoch und haben einen Umfang von bis zu 300 m im Quadrat.Depending on the pit clearance, these piers are up to 40 m high and have a circumference of up to 300 m square.

Entsprechende Schleudern sind entwickelt und erprobt wor­ den und stehen diesem Verfahren zur Verfügung.Appropriate slingshots have been developed and tested and are available for this procedure.

Diese Pfeiler sind tragend und stabil und können erfindungs­ gemäß an den Randzonen durch Injektion und/oder Torkretierung befestigt werden durch in sich abbindende Kunststoffe, die ankerartig in den großen Pfeiler wie Finger hineinragen und deren krustenförmiges Ende mit diesen Fingerankern in Ver­ bindung steht und diesen Pfeilern die entsprechende Festig­ keit an den Randzonen durch eine abdichtende, wettertechnisch gute Leitfläche verleiht.These pillars are load-bearing and stable and can be inventive according to the edge zones by injection and / or gate locking are fastened by self-setting plastics that protrude like an anchor into the large pillar like fingers and the crust-shaped end with these finger anchors in ver bond and these pillars have the appropriate strength due to a sealing, weather-related gives good guidance surface.
