Abstract
Description
Aufgabe der Erfindung ist es ein Verfahren zu schaffen, das die Gefährlichkeit der Flächen und Abraumhalden durch radio aktive Stäube, beseitigt. Vom Stand der Technik her, ist an sich nur das Abtragen und sichere Deponieren der Bodenflächen bekannt. Da es sich aber km2, also um ganz erhebliche Flächen und zig Abraumhalden handelt, ist diese Art der Dekontami nierung nicht möglich.The object of the invention is to provide a method which eliminates the danger to the surfaces and tailings piles from radioactive dusts. From the state of the art, only the removal and safe depositing of the floor surfaces is known per se. However, since it is km 2 , that is, very large areas and tens of dumps, this type of decontamination is not possible.
Gelöst wird diese Aufgabe durch Anspruch 1, sowie durch Unteransprüche.This problem is solved by claim 1 and by Subclaims.
Wie allgemein bekannt, sind in den Räumen Sachsen und Thüringen erhebliche Flächen, resultierend aus der berg männischen Gewinnung von Uranoxyd, radioaktiv kontaminiert. Ein Versuch diese Flächen abzutragen, ist von vorn herein zum Scheitern verurteilt, da die Flächen zu groß sind. Auch das Verbringen des Haldenmaterials zurück in die Schächte, ist nicht machbar. Die einzige Sicherung des menschlichen Lebensraumes vor diesen radioaktiven Substanzen, ist die Abdeckung. An horizontalen Flächen ist dies relativ einfach, an den Hängen der Abraumhalden jedoch mit großen Schwierig keiten verbunden, da die Halden mit einer Höhe von 50-100 m, als Spitzkegel ausgebildet sind und einen Böschungswinkel von 45° haben. Die besonderen klimatischen Verhältnisse im Umkreis der Halden, starke Erhitzung der Oberfläche durch Sonneneinstrahlung bis zu 70°C an der Oberfläche, führt zu Aufwinden und radioaktiven Staubwolken. As is well known, Saxony and Thuringia considerable areas resulting from the mountain male extraction of uranium oxide, radioactively contaminated. An attempt to remove these areas is from the start doomed to fail because the areas are too large. Also bringing the stockpile material back into the shafts, is not possible. The only backup of the human Habitat before these radioactive substances is the Cover. This is relatively easy on horizontal surfaces, on the slopes of the slag heaps, however, with great difficulty connected because the heaps are 50-100 m high, are designed as a pointed cone and an angle of repose of 45 °. The special climatic conditions in the Circumference of the heaps, strong heating of the surface by Sun exposure up to 70 ° C on the surface leads to Winding up and radioactive dust clouds.
Halden sind also Extremflächen, die sich auch nicht von selbst begrünen. Der Grund hierfür liegt in der Zusammen setzung des Haldenmaterials. Das Gestein aus der Tiefe kann erhebliche Anteile an Pyrit enthalten. Dieses wegen seines goldglänzenden Aussehens auch Katzengold genannte schwefelhaltige Mineral verwittert an der Luft zu Sulfat, wodurch ein extrem saueres Bodenmilieu entsteht, das ein heimischen Pflanzen das Leben schwer macht. In diesem saueren Milieu steigt die Konzentration von aus dem Ge stein freigesetzten Aluminium stark an. Freies Aluminium wirkt als Zellgift für jede Pflanze, die sich auf der Halde ansiedeln will.So stockpiles are extreme areas that are not different green yourself. The reason for this lies in the togetherness settlement of the stockpile material. The rock from deep can contain significant amounts of pyrite. This is because also called cat gold due to its shiny gold appearance sulfur-containing mineral weathered to sulfate in the air, which creates an extremely acidic soil environment makes life difficult for domestic plants. In this acidic environment, the concentration increases from the Ge stone released aluminum. Free aluminum acts as a cell poison for every plant that is on the Halde wants to settle.
Um trotzdem hier Abhilfe zu schaffen sind Versuche be kannt mit fahrbaren Tanks, mit einem eingebauten Rühr werk, in welchen ein Gemisch aus Saatgut, gehäckseltem Stroh als Mulchmaterial, Kalk zur Reduzierung der Boden säure, Mineraldünger und Wasser zu eienm Haftboden auf bereitet wird, der dann mit einer Art Wasserwerfer bis zu 50 m weit auf die Halde gespritzt werden kann. Damit diese Naßansaat nicht vom Wind verweht oder vom ersten Regen weggewaschen wird, fügt man dem Gemisch einen synthetischen Kleber hinzu, der die aufgebrachte Saat an die Halde binden soll.In order to remedy this, attempts are to be made knows with mobile tanks, with a built-in stirrer plant in which a mixture of seeds, chopped Straw as mulch material, lime to reduce the soil acid, mineral fertilizer and water to an adhesive floor is prepared, which then with a kind of water cannon can be sprayed onto the stockpile at a distance of 50 m. In order to this wet sowing does not blow from the wind or from the first Rain is washed away, you add one to the mixture synthetic glue added to the seed applied bind to the heap.
Aber diese Versuche haben bis jetzt zu keinen akzepta blen Ergebnis geführt.But these attempts have so far had no acceptance led result.
Durch die Zugabe der stark faserhaltigen Reststoffe sowie des Geotextils, wird eine bedeutend bessere Bodenhaftung des Substrats erreicht. Da auf der anderen Seite der Papier abfall zum Teil organischen Ursprungs ist, ist eine Ver witterung und somit eine Humusbildung gegeben. Auch die mineralischen Bestandteile des Papierreststoffes können nur als wachstumsfördernd angesehen werden. By adding the high-fiber residues as well of geotextile, becomes a significantly better grip of the substrate reached. Because on the other side of the paper waste is partly organic, is a ver weather and thus a humus formation. Also the mineral components of the residual paper can can only be viewed as promoting growth.
Um eine dauerhafte Abdeckung und Begrünung der Halden zu erreichen müssen die Haldenhänge durch serpentinen artige Baustraßen gebrochen werden, sodaß einzelne Hang segmente entstehen die dann leichter zu bearbeiten sind. Um eine Staubbildung zu vermeiden, ist eine dauernde Be feuchtung während des Arbeitsvorganges unerläßlich.For permanent coverage and greening of the stockpiles the slopes of the stockpile must be reached by serpentines Like construction roads are broken, so that individual slope segments are created which are then easier to edit. In order to avoid dust formation, permanent Moisture indispensable during the work process.
Durch das zusammenwirken aller Komponente wie Geotextil, aufgebrachtes Substrat mit Pflanzen und Grassamen, sowie der jungen Bäume, ensteht eine abdeckender Pflanzentepich der auf Dauer in der Haldenhängen Halt hat und durch die Baustraßen auch leicht zu kontrollieren und pflegen ist.By the interaction of all components like geotextile, applied substrate with plants and grass seeds, as well of the young trees, a covering plant carpet is created who has a permanent hold in the slope slopes and through the Construction roads are also easy to control and maintain.
