Description
Verfahren zum Binden von Staub im Kohlenbergbau Zusatz zur Patentanmeldung C 6032 VI/5d Gegenstand der Hauptpatentanmeldung C 6032 VI/5d ist ein pastenförmiges Mittel zum Binden von Kohlenstaub auf Firsten und Stößen, das durch ein wasserhaltiges Gemisch gekennzeichnet ist, welches ein hygroskopisches Salz bzw. ein Gemisch hygroskopischer Salze, einen Emulgator, ein Netzmittel bzw. einen solchen Stoff, der einulgierende und, netzende Wirkungen zugleich ausübt, und das gallertartige Umsetzungsprodukt aus kristallisiertem Chlormagnesium und Kalkhydrat enthält.The method is for binding dust in the coal addition to the patent application C 6032 VI / 5d subject of the main patent application C 6032 VI / 5d is a paste-like means for binding of coal dust on ridges and bumps, which is characterized by a hydrous mixture comprising a hygroscopic salt or a mixture of hygroscopic salts, an emulsifier, a wetting agent or such a substance that has emulsifying and wetting effects at the same time, and contains the gelatinous reaction product of crystallized chlorine magnesium and hydrated lime.
Gegenstand der Erfindung ist ein. Verfahren zum Binden von Staub im Kohlenbergbau durch Regenerieren der Masse, die sich aus der auf Firsten und Stößen aufgetragenen Paste der Hauptpatentanmeldung C 6032 VI/5d und aus von der Paste aufgenommenem Staub gebildet hat. Dieses Verfahren der Regenerierung wird in der Weise ausgeführt, daß auf diese Masse, deren Staubbindefähigkeit nahezu oder vollständig erschöpft ist, ein trockenes Gemisch aus einem hygroskopischen Salz bzw. einem Gemisch hygroskopischer Salze, einem Emulgator und einem Netzmittel bzw. einem solchen Stoff, der emulgierende und netzende Wirkung zugleich ausübt, aufgebracht wird.The invention is a. Process for binding dust in coal mining by regenerating the mass which has formed from the paste of the main patent application C 6032 VI / 5d applied to roofs and joints and from dust taken up by the paste. This regeneration process is carried out in such a way that a dry mixture of a hygroscopic salt or a mixture of hygroscopic salts, an emulsifier and a wetting agent or such a substance, the emulsifying agent, is applied to this mass, whose dust binding capacity is almost or completely exhausted and wetting effect at the same time.
Das Verfahren der Erfindung bietet den Vorteil, daß die nach Staubaufnahme erschöpfte Paste nicht von den Firsten und Stößen entfernt werden muß, sondern durch Aufbringen der wirksamen Bestandteile über einen längeren Zeitraum, vielfach bis zu, einem Jahr, regeneriert werden kann.The method of the invention offers the advantage that after dust pick-up exhausted paste does not have to be removed from the roofs and joints, but through Applying the active ingredients over a longer period of time, often up to to, one year, can be regenerated.
Das Regenerieren kann beispielsweise in der Weise ausgeführt werden, daß das trockene Gemisch mit Hilfe von Preßluft durch eine Düse der Masse einverleibt wird.The regeneration can be carried out, for example, in the manner that the dry mixture is incorporated into the mass with the aid of compressed air through a nozzle will.
Für die Durchführung des erfindungsgemäßen Verfahrens sind in fclgender Weise hergestellte Gemische geeignet: 1. In 100 Teile feingemahlenes handelsübliches Chlorcalcium mit einem Gehalt von 80 bis 90 1/o Ca C12 wird in einer Mischmaschine eine Mischung, die aus 1 Teil eines Alkylphenolpolyglykoläthers und 1 Teil eines Alkylarylsulfonates besteht, eingedüst. Das Gemisch wird anschließend in einer Kugelmühle 2 Stunden lang gemahlen.Mixtures prepared in the following manner are suitable for carrying out the process according to the invention: 1. In 100 parts of finely ground commercially available calcium chloride with a content of 80 to 90 1 / o Ca C12 , a mixture consisting of 1 part of an alkylphenol polyglycol ether and 1 part consists of an alkylarylsulfonate, injected. The mixture is then milled in a ball mill for 2 hours.
2. In 100 Teile feingemahlenes handelsübliches Chlorcalciumpulver mit einem Gehalt von 80 bis 901/o Ca C12 werden in einer Mischmaschine 2 Teile Lautrylpolyglykolä,ther eingedüst. Das Gemisch wird anschließend in einer Kugelmühle 2 Stunden lang gemahlen.2. 2 parts of Lautryl polyglycol ether are injected into 100 parts of finely ground commercially available calcium chloride powder with a content of 80 to 901 / o Ca C12 in a mixer. The mixture is then milled in a ball mill for 2 hours.
