Die Erfindung betrifft ein Verfahren zum Herstellen gasdichter Streckendämme im Grubenbetrieb durch Einpressen eines pumpfähigen Gemisches aus Kalkstein, einem hydraulischen Bindemittel und Wasser in vorher errichtete Schutzwände. Solche Dämme werden im Untertagebetrieb des Steinkohlenbergbaus in der Weise hergestellt, daß man in den ausgeraubten Strecken am Dammende und am Dammanfang Stützwände errichtet und den durch diese Wände gebildeten Hohlraum zunächst mit Bergeversatz und dann mit einem pumpfähigen, aus praktisch reinem hochprozentigem Kalksteinmehl, gegebenenfalls Zement und Wasser bestehenden Brei anfüllt. Ein pumpfähiges Gemisch kann, wie aus der Zeitschrift »Glückauf«, 1954, S. 777, bekannt, aus einer Zement-Gesteinsstaubtrübe in einem Verhältnis von 1:3 der Feststoffanteile bestehen. Da die Dämme zur Verhinderung des Austritts von Grubengas gasdicht sein müssen, ist es beim bekannten Verfahren meistens erforderlich, sie nachzuverpressen oder zwei Dämme nebeneinander zu errichten.The invention relates to a method for producing gas-tight road embankments in mining operations Injection of a pumpable mixture of limestone, a hydraulic binder and water in previously erected protective walls. Such dams are used in underground coal mining Manufactured in such a way that retaining walls are placed in the looted stretches at the end of the dam and at the beginning of the dam erected and the cavity formed by these walls first with a mountain offset and then with a pumpable, made of practically pure high-percentage limestone powder, possibly cement and water replenishes existing pulp. A pumpable mixture can, as from the magazine "Glückauf", 1954, p. 777, known from a cement rock dust slurry in a ratio of 1: 3 of the solids exist. Since the dams have to be gas-tight to prevent the escape of mine gas, with the known method it is usually necessary to re-grout them or to press two dams next to each other to build.

Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden. Nach dem Verfahren der Erfindung erfolgt die Herstellung gasdichter Streckendämme im Grubenbetrieb durch Einpressen eines pumpfähigen Gemisches aus Gesteinsstaub, einem hydraulischen Bindemittel und Wasser zwischen vorher errichtete Stützwände in der Weise, daß ein mindestens 5% Ton enthaltender Kalkmergel verwendet wird.The invention is based on the object of avoiding this disadvantage. According to the procedure of Invention, the production of gas-tight road embankments takes place in the mine by pressing in a pumpable mixture of rock dust, a hydraulic binder and water between before erected retaining walls in such a way that a lime marl containing at least 5% clay is used.

Vergleichsversuche haben ergeben, daß ein solches Gemisch keinen Volumenverlust aufweist, worauf bei Verwendung der bekannten Mittel zur Herstellung von Dämmen im Naßverfahren zurückzuführen ist, daß die Dämme nicht völlig gasdicht sind.Comparative tests have shown that such a mixture has no loss of volume, whereupon when using the known means for the production of dams in the wet process is due, that the dams are not completely gas-tight.

Zur Durchführung der Vergleichsversuche wurden die aus der nachstehenden Tabelle ersichtlichen Stoffe mit Wasser bis zu einer pumpfähigen Konsistenz angerührt, in Standzylinder gefüllt und der Volumenverlust gemessen.The substances shown in the table below were used to carry out the comparative tests mixed with water to a pumpable consistency, filled into standing cylinders and the loss of volume measured.

Mit Hilfe des erfindungsgemäßen Gemisches lassen sich ohne Nachverpressen völlig gasdichte Dämme im Naßverfahren herstellen, da beim Erhärten des Gemisches kein Volumenverlust eintritt.With the aid of the mixture according to the invention, completely gas-tight dams can be created without further grouting Manufacture using the wet process, as there is no loss of volume when the mixture hardens.

Trotz der verhältnismäßig hohen, für die Pumpfähigkeit des erfindungsgemäßen Gemisches erforderlichen Wassermenge weist das erhärtete Gemisch ausgezeichnete Festigkeitswerte bei einer für gasdichte Dämme im Bergbau erwünschten Elastitizität auf. Der für Zwecke der Erfindung in Frage kommende Kalkmergel kann so viel Ton enthalten, wie es die für den Damm erforderliche Festigkeit zuläßt. Es empfiehlt sich, in der Regel einen Kalkmergel zu verwenden, der nicht mehr als etwa 10 % Ton enthält.Despite the relatively high levels required for the pumpability of the mixture according to the invention Amount of water, the hardened mixture has excellent strength values at one for gas-tight Dams on the elasticity desired in mining. The one in question for the purposes of the invention Lime marl can contain as much clay as the strength of the dam allows. It it is recommended to use a lime marl that does not contain more than about 10% clay.
