Beschreibung und Erläuterung zur ZusatzpatentanmeldungDescription and explanation of the additional patent application
"Spritzmassen zur Verfestigung des frisch geschnittenen Gebirges, vorzugsweise für Bergbaustrecken mit frühtragender Biege-, Zug- und Druckfestigkeit" Zusatz zu P 31 17 43Q.1."Gunning mixes to consolidate the freshly cut mountains, preferably for mining routes with early bending, tensile and compressive strength " Addition to P 31 17 43Q.1.
In der Hauptanmeldung "Spritzmassen zur Verfestigung des frisch- geschnittenen Gebirges9 vorzugsweise für Bergbaustreckenfl P 31 17 436.1 wird eine Spritzmasse beschrieben, vorzugsweise zur Verfestigung des angrenzenden Gebirges nach dem Auffahren von Grubenstrecken, die gekennzeichnet ist durch das Aufnehmen der Restprodukte von Rauchgasentschwefelungsanlagen, die hinter Kohlekraftwerken angesetzt sind und das zusätzliche Nischen von Anhydrit, Elektrofilterstaub, Mineralwollfasern, Zement und Calciumchlorid.In the main application "Injection molding compounds for solidifying the freshly cut Gebirges9 preferably for mining routes P 31 17 436.1 is a gunning compound described, preferably to consolidate the adjacent mountain range after driving of mine sections, which is characterized by the collection of residual products of flue gas desulphurization systems that are installed behind coal-fired power plants and the additional niches of anhydrite, electrostatic precipitator dust, mineral wool fibers, cement and calcium chloride.
Um die Festigkeit beim frisch angeschnittenen Gebirge in Minutenschnelle in einem Bereich von vorzugsweise über 70 kp/cm² zu erzielen, wird erfindungsgemäß vorgeschlagen, eine Spritzmasse zu verwenden, der zu den in der oben genannten Patentanmeldung angeführten Zuschlagstoffen zusätzlich anstelle von Mineralwollfasern z.B. Glasfaser und/oder Stahlfasern und erfindungsgemäß Naturanhydrit, vorzugsweise synthetischer Anhydrit sowie Stearate, vorzugsweise Aluminium-Tristearate, zugegeben werden.About the strength of the freshly cut mountains in a matter of minutes to achieve in a range of preferably over 70 kp / cm², is according to the invention proposed to use a molding compound, which is in the above-mentioned patent application listed aggregates in addition to mineral wool fibers, e.g. glass fiber and / or steel fibers and, according to the invention, natural anhydrite, preferably synthetic Anhydrite and stearates, preferably aluminum tristearates, are added.
Dieses Stearat bringt für die spezifischen notwendigen Eigenschaften der Konsolidierung beim frisch geschnittenen Gebirge den Frühtrage-Effekt.This stearate brings about the specific properties necessary the consolidation in freshly cut mountains has the early wearing effect.
Nachstehend wird die erfindungsgemäße Auflistung der Ergänzungsmischung angeführt.The following is the listing of the supplement mixture according to the invention cited.
Stearate, vorzugsweise Aluminium-Tristearate, bringen den gewünschten notwendigen Vorteil Das Zumischen des genannten spezifischen Stearates oder der Mischung verschiedener Stearate wird erfindungsgemäß nur für den Bereich von 0,3 - 2 % angeführt, da erfindungsgemäß für das Streckenkonsolidierungsmaterial gerade dieser Mischungsbereich die spezifischen notwendigen Eigenschaften garantiert.Bring stearates, preferably aluminum tristearates the Desired necessary benefit Mixing in the specific stearate mentioned or the mixture of different stearates is according to the invention only for the range of 0.3-2%, since according to the invention for the route consolidation material It is precisely this mixing range that guarantees the specific properties required.
Es wurde gefunden, daß das Aluminium-Tristearat mit seiner besonderen Eigenschäft, eine Biege-, Zug- und Druckfestigkeit garantiert, die man bisher nur mit teuren Zuschlagstoffen wie Epoxydharz und Alpha-Gipsen erzielt hat, wobei diese Epoxydharze für den Untertage-Bergbau nur notgedrungen zugelassen werden, da sie a) bei Brandgefahr eine Gefährdung für die Arbeitsmannschaft bringen und das Formaldehyd in den Harzen auch durch stetige Ausdunstung eine Arbeitsplatzbelästigung bewirkt.It was found that the aluminum tristearate with its special Properties that guarantee flexural, tensile and compressive strength that were previously only available using expensive aggregates such as epoxy and alpha plasters, these have been achieved Epoxy resins for underground mining are only permitted by necessity, as they are a) in the event of a fire hazard, the work crew and the formaldehyde in the resins also a nuisance to the workplace due to constant evaporation causes.
b) Der Preis dieser erfindungsgemäßen Masse beträgt nur einen Bruchteil der bisher bekannten Konsolidierungsmassen mit Bindeharzzusätzen.b) The price of this mass according to the invention is only a fraction the previously known consolidation masses with binder resin additives.
Nachstehend wird die erfindungsgemäße Mischung beschrieben: 1.) ca. 60 % Gips, vorzugsweise aus der Rauchgasentschwefelung hinter Kohlekraftwerken bzw. Gasreinigungsanlagen anderer Verbrennungseinrichtungen; 2.) ca. 11 % Anhydrit, vorzugsweise synthetischer Anhydrit; 3.) ca. 15 * Elektrofilterstaub, ebenfalls anfailend vorzugsweise hinter Kohlekraftwerken; 4.) ca. 3 % faserartige Armierungsstoffe; 5.) ca. 11 % Zement der Qualitätsgüte PZ 450 F und/oder PZ 550 F, PZ 600 Fg 6.) ca. 2,5 % Calciumchlorid-Dihydrat, das hinter Kohlekraftwerks-Rauchgasentschwefelungsanlagen vorzugsweise ausgeschleust wird; 7.) 0,3 - 2 * Stearate oder deren Gemische, vorzugsweise Aluminium-Tristearat.The mixture according to the invention is described below: 1.) approx. 60% gypsum, preferably from flue gas desulphurization behind coal-fired power plants or Gas cleaning systems for other incineration facilities; 2.) approx. 11% anhydrite, preferably synthetic anhydrite; 3.) approx. 15 * electrostatic precipitator dust, also received preferably behind coal-fired power plants; 4.) approx. 3% fibrous reinforcing materials; 5.) approx. 11% Cement of the quality grade PZ 450 F and / or PZ 550 F, PZ 600 Fg 6.) approx. 2.5% calcium chloride dihydrate, which is behind coal-fired flue gas desulphurisation systems is preferably discharged; 7.) 0.3-2 * stearates or mixtures thereof, preferably Aluminum tristearate.
