« Arnold Haarmann in Brambauer b. Dortmund. Vorrichtung zur Lockerung und Hereingewinnung von KoIiIe. Patentiert im Deutschen Reiche vom 28. März 1923 ab. «Arnold Haarmann in Brambauer b. Dortmund. Device for loosening and extracting colts. Patented in the German Empire on March 28, 1923.

Die Arbeitsweise der zur Gewinnung vonThe way in which to extract

Kohle verwendeten Hacken und mechanisch betriebenen Abbauhämmer wirkt sich dahin aus, daß eine keilförmige Spitze oder Schneide in das Gebirge getrieben wird. Allen Keilvorrichtungen haftet der Nachteil an, daß ein großer Teil der aufgewendeten Arbeit als Reibung verlorengeht und die Wirkung des Keiles sich immier nur auf verhältnismäßig kleine Kohlenteile erstreckt.Coal used hoes and mechanically operated pick hammers will do this from that a wedge-shaped point or cutting edge is driven into the mountains. All wedge devices have the disadvantage that Much of the work expended is lost as friction and the effect of the wedge always extends only to relatively small pieces of coal.

Es ist versucht worden, auf dem Wege der Kraftübertragung mittels einer Flüssigkeit diese Reibungsverluste zu vermeiden und den Wirkungsbereich der verwendeten Kraftquelle dadurch zu vergrößern, daß 'die zur Kraftübertragung verwendete Flüssigkeit in die feinsten Schlechten des Gebirgskörpers dringt und durch Erweiterung der Schlechten das Gebirge auflockert und Teile desselben absprengt. Attempts have been made by the way of To avoid power transmission by means of a liquid and to avoid these friction losses To increase the effective range of the power source used, that 'the power transmission The liquid used penetrates the finest bads of the mountain body and by expanding the wicked, loosens the mountains and blows off parts of them.

Nach der englischen Patentschrift 19045 vom Jahre 1897 wild «β» in ein Bohrloch eingeführtes^ zum Zwecke der Zerklüftung des Gebirges mechanischen Stoßen ausgesetzt. Nach der deutschen Patentschrift 241966 der Kl. 5b wird die hereinzugewinnende Kohle zunächst mit einer Flüssigkeit durchtränkt, darauf die Tränkflüssigkeiti durch einen Druckübersetzer einer plötzlichen Druckerhöhung ausgesetzt.According to the English patent specification 19045 from 1897, "β" introduced into a borehole wildly exposed to mechanical shocks for the purpose of fissuring the rock. According to the German patent specification 241966 of class 5b, the to be gained Charcoal first impregnated with a liquid, then the impregnating liquidi exposed to a sudden increase in pressure by a pressure intensifier.

Die zur Durchführung der beiden Verfahren in den angezogenen Patentschriften angegebenen Vorrichtungen gestatten nicht, die infolge der porösen Natur der Kohle erfor-The specified for carrying out the two processes in the cited patents Devices do not allow the necessary due to the porous nature of the coal

a5 derliche große Flüssigkeitsmenge unter hohem Druck in das Gebirge einzuführen; vielmehr ermöglichen sie nur das Einpressen einer gegebenen Flüssigkeitsmenge, nämlich der Füllung der Vorrichtung (englisches Patent 19045) b2w. der zur Tränkung verwendeten Menge (deutsches Patent 241966).a5 such a large amount of liquid under high To introduce pressure into the mountains; rather, they only allow a given amount of liquid to be pressed in, namely the filling of the device (English patent 19045) b2w. those used for impregnation Amount (German patent 241966).

Demgegenüber soll die neue Vorrichtung auf dem Wege der absetzenden Nachströmung von Wasser es ermöglichen, eine beliebig große Flüssigkeitsmenge unter hohem Druck in das Gebirgsinnere einzuführen.In contrast, the new device on the way of the settling post-flow of water make it possible to introduce any large amount of liquid under high pressure into the interior of the mountain.

Die Zeichnung stellt eine mögliche Ausführungsform der Einrichtung dar. Sie besteht in einer Hochdruckkolbenpumpe mit schnellaufendem Tauchkolben k, dem Einlaßventil r und dem Auslaßventil v. Das Druckrohr der Pumpe ist in der vom »Stoßtränk? verfahren« her bekannten Weise als Doppelrohr ausgebildet und mit einem Dichtungskörper d versehen. Dieses Doppelrohr wird in ein Bohrloch eingeführt und durch den: Dichtungskörper d gegen die Bohrlochwandung abgedichtet.The drawing shows a possible embodiment of the device. It consists of a high-pressure piston pump with a high-speed plunger piston k, the inlet valve r and the outlet valve v. The pressure pipe of the pump is in the one from the »shock drinker? method «ago designed as a double tube and provided with a sealing body d . This double pipe is inserted into a borehole and sealed against the borehole wall by the sealing body d.

Der Antrieb des Kolbens k erfolgt beispielsweise durch einen Preßluftmotor. Beim' Arbeiten des Werkzeugs fließt das in den Gebirgskörper einzupressende Wasser durch den Saugstutzen s und das zweckmäßig als Ringventil ausgebildete Rückschlagventil r m die Arbeitskammer e. In dieser Kammer ruft der Preßkolben k explosionsartige Drucksteigerungen (etwa 100 bis 1000 je Minute) hervor, die sich durch das Doppelrohr bis in das Innere des Gebirgskörpers fortpflanzen.The piston k is driven, for example, by a compressed air motor. When the tool is working, the water to be pressed into the rock flows through the suction nozzle s and the non-return valve rm the working chamber e, which is expediently designed as a ring valve. In this chamber, the plunger k causes explosive increases in pressure (about 100 to 1000 per minute), which propagate through the double tube into the interior of the rock.

Es sind noch andere Ausführungsformen möglich; das Wesea der Erfindung besteht in der Verwendung einer in ein Bohrloch unter fester Verdammung gegen die Bohrwand eingeführten Hochdruckkolbenpumpe mit absetzender Nachströmung von Wasser.Other embodiments are also possible; the essence of the invention exists in the use of one in a borehole under solid dam against the drilling wall Introduced high-pressure piston pump with settling post-flow of water.
