Description
Verfahren zum Herstellen befahrbarer Entwässerungsbohrungen in Kohlenflözen Die Erfindung betrifft ein Verfahren zum Herstellen befahrbarer Entwässerungsbohrungen in Kohlenflözen, indem aus einem runden Bohrloch .ein Langloch hergestellt wird, so daß das hergestellte Langloch befahren werden kann. Das Verfahren erfolgt nun @erfindun,gsgemäß in der Weise, daß nach Vortrieb eines weiten Bohrloches von gewünschter Tiefe auf die Führungsringe des Drehbohrgestänges Sclmeidmesser aufgesetzt werden und das Gestänge um die 'Füh @ungsüngentfeinung während des Drehbobrens hin und her bewegt wird, nachdem zwischen Bohrgestänge und Bohrantrieb außerhalb des Bohrloches ein Gelenkstück eingeschaltet ist, das ein ,gleichmäßiges Absinken des ganzen Gestänges beim Arbeiten iii dem entstehenden Langloch ermöglicht. Die Herstellung derartiger befahrbarer Langlöcher ist gegenüber der Herstellung von Stollen mittels Handbetrieb oder mittels sogenannter Stollenbagger wirtschaftlicher, weil sie billiger und schneller erfolgt.A method of manufacturing navigable drainage holes in coal seams, the invention relates to a method for producing navigable drainage holes in coal seams, by made of a round borehole .a long hole, so that the slot produced can be driven. The method now takes place in such a way that after driving a wide borehole of the desired depth on the guide rings of the rotary drill rods, cutting blades are placed and the rod is moved to and fro around the 'Füh @ ungsüngentfeinung during the rotary drilling, after between drill rods and drill drive outside of the borehole a joint piece is switched on, which enables a uniform lowering of the entire rod when working iii the resulting elongated hole. The production of such drivable elongated holes is more economical than the production of tunnels by manual operation or by means of so-called tunnel excavators because it is cheaper and faster.
Es wird darauf hingewiesen, daß es bereits bekannt ist, im Kohlenflöz vorgetriebene Bohrlöcher mit Hilfe einer ähnlichen Anordnung vor Kopf zu erweitern, um dort eine größere Menge Sprengstoff unterbringen zu können. Auch sind Vorrichtungen zur Herstellung von Lang- und Querschlitzen im Schrämbetrieb bekannt, die ähnlich arbeiten wie die erfindungsgemäße Vorrichtung. Demgegenüber handelt @es sich aber beim Erfindungsgegenstand darum, Entwässerungslöcher, die im Flöz vorgetrieben werden, nach unten zu vertiefen, um dadurch gleich einen befahrbaren Stollen zu erhalten.It should be noted that it is already known in the coal seam to widen driven boreholes with the help of a similar arrangement in front of the head, in order to be able to accommodate a large amount of explosives there. Also are devices for the production of long and transverse slots in the cutting operation known that are similar work like the device according to the invention. In contrast, @es is in the subject matter of the invention, drainage holes that are driven in the seam, to deepen downwards in order to obtain a drivable tunnel.
Eine Weiterausgestaltung der Erfindung besteht ferner darin, daß der vorderste Ring außer mit den auch auf den übrigen Führungsringen angeordneten Messern noch mit Messern ,an der Stirnseite ausgerüstet ist, um dadurch :ein Freischneiden auch an der Stirn des Bohrloches zu erreichen.Another embodiment of the invention is that the foremost ring except with the knives arranged on the other guide rings is still equipped with knives on the front side to thereby: a free cutting can also be reached at the forehead of the borehole.
