Description
Verfahren zur Staubbekämpfung im Bergbau Im Hauptpatent 804203 ist ein Verfahren zur Staubbekämpfung im Bergbau angegeben, bei dem wäßrige Lösungen, die höhermolekulare Alkylarylsulfonate mit Seitenketten mit mindestens io C-Atomen und gegebenenfalls mehrwertige hygroskopische Alkohole, insbesondere Triglykol, enthalten, verwendet werden.Process for dust control in mining In the main patent 804203 is a method for dust control in mining specified in which aqueous solutions, the higher molecular weight alkylarylsulfonates with side chains with at least 10 carbon atoms and optionally polyhydric hygroscopic alcohols, especially triglycol, included.
Es wurde nun gefunden, daß man bei der Staubbekämpfung im Bergbau auch Lösungen anderer Netzmittel als die genannten Alkylarylsulfonate mit gutem Erfolg verwenden kann, wenn man sie zusammen mit mehrwertigen hygroskopischen Alkoholen, insbesondere Triglykol, verwendet. Geeignete Netzmittel sind beispielsweise Salze von Alkylnaphthalinsulfonsäuren, Fettalkoholsulfonate, Mineralölsulfonate, Türkischrotöle, sulfonierte Kondensationsprodukte aus Phenolen und Formaldehyd, Salze von aus den Sulfochlorierungsprodukten höherer Paraffinkohlenwasserstoffe erhältlichen Umwandlungsprodukten, oleylaminoäthansulfonsauit Salze, ferner Abkömmlinge des Äthylenoxydes, wie feste Polyäthylenoxyde, Umsetzungsprodukte der höheren Fettsäuren, z. B. Stearinsäure, oder deren Alkylolamide, wie Kokosfettsäuremonoäthanolamid, oder der höheren Alkohole, wie Oleylalkohol, mit io und mehr Mol Äthylenoxyd. Von den mehrwertigen Alkoholen hat sich auch hier das Triglykol wegen seiner bakteriziden Wirkung als besonders brauchbar erwiesen, doch kommen auch andere mehrwertige Alkohole, wie Glykol, Diglykol, andere Polyglykole, Glycerin, sowie die wasserlöslichen Äther dieser Verbindungen in Betracht. Die angegebenen Kombinationen verändern die Staubverhältnisse vor Ort in so günstiger Weise, daß auch noch längere ±eit nach ihrer Anwendung das lästige Stäuben verhindert wird.It has now been found that you can fight dust in mining also solutions of other wetting agents than the alkylarylsulfonates mentioned with good Can use success when taken together with polyhydric hygroscopic alcohols, especially triglycol is used. Suitable wetting agents are, for example, salts of alkylnaphthalene sulfonic acids, fatty alcohol sulfonates, mineral oil sulfonates, Turkish red oils, sulfonated condensation products of phenols and formaldehyde, salts of from the Conversion products available from sulfochlorination products of higher paraffinic hydrocarbons, oleylaminoethane sulfonic acid salts, also derivatives of ethylene oxide, such as solid ones Polyethylene oxides, reaction products of the higher fatty acids, e.g. B. stearic acid, or their alkylolamides, such as coconut fatty acid monoethanolamide, or the higher alcohols, like oleyl alcohol, with 10 or more moles of ethylene oxide. From the polyhydric alcohols Here too, triglycol has proven to be special because of its bactericidal effect proven to be useful, but other polyhydric alcohols such as glycol, diglycol, other polyglycols, glycerin, as well the water-soluble ethers of this Connections into consideration. The specified combinations change the dust conditions on site in such a favorable way that even a long time after its application the annoying dust is prevented.
Beispiel In einem schräg liegenden Flöz von Fettkohle von 5 m Mächtigkeit wird die Kohle, die eine Eigentemperatur von etwa 45' C hat, in Abständen von etwa 3 bis 4 m angebohrt. In die Bohrlöcher, die eine. Tiefe von 45 bis 2 m aufweisen, werden offene oder perforierte Rohre von derselben Länge eingeführt und nach außen in geeigneter Weise abgedichtet. Unter einem Druck von 5 atü wird in die Rohre eine o,o4prozentige wäßrige Lösung eines Gemisches aus 6 Teilen des Umsetzungsproduktes aus io Mol Äthylenoxyd und i Mol Kokosfettsäureäthanolamid und 4 Teilen Triglykol eingepreßt. Die eingepreßte Menge der. wäßrigen Lösung beträgt pro Tonne abzubauenden Kohle etwa 41. Nach Beendigung der Tränkung braucht die Kohle nicht sofort abgebaut zu werden. Auch nach einigen Stunden Ruhe bleibt die Staubbindung durch die Tränkflüssigkeit erhalten, so daB ein staubfreier Abbau möglich ist.Example In a sloping seam of fat coal 5 m thick the coal, which has an intrinsic temperature of about 45 ° C, is set at intervals of about 3 to 4 m drilled. In the drill holes, the one. Have a depth of 45 to 2 m, open or perforated pipes of the same length are introduced and to the outside sealed in a suitable manner. Under a pressure of 5 atm, a 0.04 percent aqueous solution of a mixture of 6 parts of the reaction product from 10 moles of ethylene oxide and 1 mole of coconut fatty acid ethanolamide and 4 parts of triglycol pressed in. The pressed-in amount of. aqueous solution is to be degraded per ton Coal around 41. After the end of the impregnation, the coal does not need to be broken down immediately to become. Even after a few hours of rest, the dust remains bound by the soaking liquid so that dust-free degradation is possible.
Dieselbe wäßrige Lösung kann auch zur Bindung von abgelagertem Kohle- und Gesteinsstaub auf Transporteinrichtungen, Grubensohlen und insbesondere dort, wo durch Begehung oder Wetterführung eine Aufwirbelung des Staubes erfolgen kann, dienen. Man erreicht eine nahezu vollständige Staubbindung durch Verdüsen der wäßrigen Lösung mit geeigneten Sprühvorrichtungen. Die Konzentration der wäßrigen Lösung an wirksamer Substanz kann variiert werden und richtet sich nach der Staubfeinheit und dem Trockengehalt des Staubes. .The same aqueous solution can also be used to bind deposited coal and rock dust on transport equipment, pit floors and especially there, where the dust can be whirled up through inspection or weather management, to serve. Almost complete dust binding is achieved by atomizing the aqueous Solution with suitable spray devices. The concentration of the aqueous solution the active substance can be varied and depends on the fineness of the dust and the dryness of the dust. .
