KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf einen Verschluß zur Abdichtung von Hohlräumen in der Kohle, in die Druckwasser zur Vermeidung von Kohlenstaubbildung und zur Gewinnung des Überhanges eingeleitet wird.The invention relates to a closure for sealing cavities in the coal, in the pressurized water to avoid coal dust formation and for extraction of the overhang is initiated.
Die Durchtränkung der Kohle mit Wasser wird ebenso wie die Hereingewinnung mittels Druckwassers als an sich bekannt vorausgesetzt. The impregnation of the coal with water is just like the extraction by means of Pressurized water is assumed to be known per se.
ίο Der Erfolg einer guten Durchtränkung ist abhängig von einem hohen Druck, unter dem das Wasser eingeleitet wird, und ebenso auch von einem guten Verschluß des Hohlraumes.ίο The success of a good saturation is depending on a high pressure under which the water is introduced, and likewise of a good closure of the cavity.
Der Gegenstand der Erfindung ist auf der Zeichnung dargestellt, und zwar zeigen Fig. 1 einen senkrechten Schnitt durch den Kohlenstoß und die Verschlußkörper und die Fig. 2, 3, 4 und 5 zwei Ausführungsformen des Verschlusses. The object of the invention is shown in the drawing, namely FIG. 1 a vertical section through the coal face and the closure body and Fig. 2, 3, 4 and 5 two embodiments of the closure.
Nachdem in der anstehenden Kohle das Bohrloch in Absätzen hergestellt ist, wird der Hohlraum durch hintereinanderliegende konische Hülsen α α, welche mit einem Rohrstück b versehen sind, abgeschlossen und somit gegen den Kohlenstoß abgedichtet.After the borehole has been made in steps in the coal in question, the cavity is closed off by conical sleeves α α lying one behind the other, which are provided with a piece of pipe b , and thus sealed against the coal face.
Damit der Apparat gegen das Herausschleudern beim Einführen des Preßwassers geschützt ist, sind die konischen Dichtungshülsen mit Gewinde versehen. Beim Einbringen des Apparates werden durch Drehung desselben die beiden konischen Hülsen in die entsprechenden Bohrungen der Kohle eingeschraubt, wodurch der Zweck des Haltens vollständig erreicht wird.So that the apparatus is protected against being thrown out when the press water is introduced the conical sealing sleeves are threaded. When bringing in the apparatus by turning it, the two conical sleeves are inserted into the corresponding one Bores screwed in the coal, thereby fully achieving the purpose of holding will.
Das Hereindrehen des Apparates wird mittels Schraube ausgeführt, welche an einem Streckengestell angebracht ist, wobei es in kurzer Zeit möglich ist, den Apparat einzubringen. The screwing in of the apparatus is done by means of Executed screw, which is attached to a frame, where it is in it is possible to bring the apparatus in for a short time.
Das Berieselungswasser in der Grube, welches unter hohem Druck steht, wird mittels Schlauchleitung und des Hahns f mit diesem Apparat in Verbindung gebracht, worauf sich dann die Spalten oder Schlechten in der Kohle mit Wasser füllen und somit die anstehende Kohle vollständig durchtränkt wird, so daß dieselbe ohne Schießarbeit gewonnen werden kann und eine Absonderung von Kohlenstaub vermieden wird.The sprinkling water in the pit, which is under high pressure, is brought into connection with this apparatus by means of a hose line and the tap f , whereupon the crevices or bads in the coal are filled with water and thus the coal is completely saturated so that the same can be obtained without shooting and a discharge of coal dust is avoided.
In Fig. 4 und 5 wird der Verschluß des Hohlraumes durch eine Dichtungsplatte c bewirkt, welche mittels eines Spannschlosses e gegen den Kohlenstoß gepreßt wird und dadurch die Öffnung des Hohlraumes verschlossen hält.4 and 5 the closure of the cavity is effected by a sealing plate c which is pressed against the coal face by means of a turnbuckle e and thereby keeps the opening of the cavity closed.
