Bekannt ist die Hereingewinnung der Kohle von Hand, mit Abbauhämmern, durch Abtreibe-, Schräm- und Schießarbeit. Ferner sind maschinelle Abbauvorrichtungen bekannt geworden. Letztere sollen nach Herstellen eines Schrames die Kohle abdrücken. Außerdem ist ein Verfahren bekannt geworden, mittels eines Seiles einen ganzen Pfeiler zu unterschrämen, um ihn dann hereingewinnenIt is well known that coal is extracted by hand, with hammers Abortion, cutting and shooting work. Mechanical mining devices are also known become. The latter are supposed to push the charcoal after making a scribe. aside from that a method has become known to close a whole pillar by means of a rope undercame, to then win him in ίο zu können. Das neue Verfahren baut sich auf der Herstellung von Bohrlöchern auf, welche von einer Strebstrecke zur anderen, also, abgesehen von kurzen Hilfslöchern, durch den ganzen Pfeiler gebohrt werden.ίο to be able to. The new process builds up on the production of boreholes, which go from one longwall to another, so, apart from short auxiliary holes, be drilled through the whole pillar. Die Bohrlöcher werden meist parallel zum Strebstoß und immer mit einer gut abzudrückenden Vorgabe gebohrt. Das Verfahren kann bei Streb-, Pfeiler- und Stoßbau angewandt werden und immer da, wo sich lange Bohrlöcher zu dem gegebenen Zweck bohren lassen. Der Erfolg des Verfahrens baut sich auf der hohen Leistungsfähigkeit der Schnelldrehkohlenbohrmaschine auf. Durch das neue Verfahren soll die Schräm- und Schießarbeit vermieden werden.The drill holes are usually parallel to the butt joint and always with a well that can be pressed off Default drilled. The method can be used for longwall, pillar and butt construction and wherever there is a long time Have holes drilled for the given purpose. The success of the process builds on the high performance of the high-speed coal drill on. The new method is intended to avoid cutting and shooting work. Neu ist das Verfahren als solches, Hochbringen eines langen Bohrloches zwecks Hereingewinnung der Kohle durch Durchtreiben eines Druckkörpers. Von dem unteren Ort b \ wird ein Bohrloch c beliebigen Durchmessers zur oberen Strecke δ1 hochgebracht. Durch das Bohrloch c wird ein starkes Seil d gezogen. An dem oberen Ende des Seiles d ist eine Maschine f angeschlossen, während das andere Ende mit einem Druckkörper e versehen ist. Die Maschine f hat ihren Stand auf dem Kohlenstoß bzw. im Streckenbahnbruch. Durch Anzug des Seiles d wird der Druckkörper e durch das Bohrloch c gezogen, und es erfolgt auf diese Weise durch die Druckwirkung die Hereingewinnung der Kohle. Die Reibung des Druckkörpers im Bohrloch wird durch entsprechende Einrichtung des Druckkörpers herabgemindert. Je nach Stärke der Zugmaschine f wird die Vorgabe des Stoßes g, g1, g2, gs entsprechend stark gewählt. Der Bergeversatz h folgt in bekannter Weise.What is new is the process as such, bringing up a long borehole for the purpose of extracting the coal by driving through a pressure hull. A borehole c of any diameter is drilled from the lower location b \ to the upper section δ 1 . A strong rope d is pulled through the borehole c. A machine f is connected to the upper end of the rope d , while the other end is provided with a pressure body e . The machine f has its position on the coal face or in the broken line. By tightening the rope d , the pressure body e is pulled through the borehole c, and in this way the coal is extracted by the pressure effect. The friction of the pressure hull in the borehole is reduced by appropriate means of the pressure hull. Depending on the strength of the tractor f , the specification of the impact g, g 1 , g 2 , g s is selected to be correspondingly strong. The mountain offset h follows in a known manner. Paten γ-Anspruch:Sponsorship γ claim: Verfahren zur Hereingewinnung von Kohle, dadurch gekennzeichnet, daß zwischen zwei Strecken in entsprechendem Abstande vom Stoß ein Bohrloch hergestellt und durch Hindurchziehen eines Druckkörpers durch das Bohrloch der Streifen zwischen Bohrloch und Stoßfläche abgesprengt wird.Process for the extraction of coal, characterized in that between a borehole is made two stretches at an appropriate distance from the joint and by pulling a pressure body through the borehole, the strips between the borehole and the abutment surface is blasted off.
