Verfahren zum Ausfüllen von Hohlräumen zwischenMethod of filling voids between
Gebirge und Ausbau beim Auffahren von Strecken im Bergbaubetrieb Grubenräume, insbesondere Abbaustrecken, werden vorzugsweise mittels Bohr- oder Sprengarbeit hergestellt. Dabei wird der nach Abförderung des hereingebrochenen Haufwerks entstandene Raum durch entsprechenden Ausbau gegen Steinfall gesichert.Mountains and expansion when driving routes in the mining operation pit rooms, in particular mining routes, are preferably carried out by means of drilling or blasting work manufactured. The resulting pile after removal of the broken-in debris is thereby used Room secured against falling stones by appropriate expansion.
Da Jedoch das Gebirge unregelmäßig bricht, entsteht zwischen dem Ausbau und dem Gebirge ein mehr oder weniger großer Hohlraum. Dieser Hohlraum muß Jedoch weitgehend verfüllt werden, um das Nachbrechen von Gestein, das den Ausbau beschädigen oder zerstören kann, zu vermeiden.However, since the mountains break irregularly, there is between the expansion and the mountains a more or less large cavity. However, this cavity must to be largely backfilled in order to break up the rock, which will damage the expansion or destroy it, avoid it.
Das Verfüllen der Hohlräume kann beispielsweise mit Gesteinsbrocken erfolgen, die aus dem Haufwerk ausgelesen und von Hand hinter die Ausbaumatten gepackt werden. Diese Arbeitsweise erfordert Jedoch einen erheblichen Zeit- und Arbeitsaufwand. Es sind auch Verfahren bekannt, wonach die Hohlräume durch Hinterpressen von abbindenden Materialien, wie beispielsweise Beton oder Kunststoffschaum, ausgefüllt werden. Nachteilig dabei ist, daß in diesen Fällen der Verzug sehr sorgfältig abgedichtet werden muB, um ein Herausquellen der Verfüllmasse zu verhindern. Diese Abdichtung läßt sich nach einer besonderen Ausgestaltung dieser Arbeitsweise vereinfachen, wenn der als VerfÜllmaterial dienende Kunststoffschaum in Schlauchfolien von geeigneter Form und Größe eingepreßt w5rd.The filling of the cavities can be done, for example, with rocks which are read from the pile and packed by hand behind the expansion mats will. However, this mode of operation requires a considerable amount of time and effort. There are also known methods, according to which the cavities by pressing back setting Materials like for example concrete or plastic foam filled in will. The disadvantage here is that in these cases the delay is very carefully sealed must be in order to prevent the filling compound from swelling out. This seal can be simplified according to a special embodiment of this mode of operation, if the plastic foam used as filling material in tubular films is more suitable Shape and size pressed in w5rd.
Aufgabe der vorliegenden erfindung war es, ein Verfahren zu inden, wonach das Verfüllen solcher Räume noch schneller und mit noch geringerem Arbeitsaufwand durchgeführt werden kann.The object of the present invention was to inden a process after which the filling of such spaces even faster and with even less work can be carried out.
Gegenstand der vorliegenden Erfindung ist ein Verfahren zum Ausfüllen von Hohlräumen zwischen Gebirge und Ausbau beim Auffahren von Strecken im BergbauoeQrieb unter Verwendung von ausgefüll-ten Schlauchfolien. Das Verfahren zeichnet sich dadurch aus, daß in die zu verfüllenden Räume luftdichte und mit einem Füllventil versehene Schlauchfolien eingebracht und anschließend mit Druckluft aufgeblasen werden.The present invention relates to a method of filling out of cavities between mountains and expansion when driving routes in mining operations using filled-in tubular films. The procedure is characterized by it from that in the rooms to be filled airtight and provided with a filling valve Tubular films are introduced and then inflated with compressed air.
Solche Schlauchfolien können, zwecks Anpassung an die verschiedenen Hohlräume in unterschiedlicher Form und Größe hergestellt werden. Als Material einen sich die üblicherweise für die Folienherstellung verwendeten Kunststoffe. Insbesondere haben. sich Schlauchfolien aus Polyäthylen bewährt.Such tubular films can, in order to adapt to the various Cavities can be produced in different shapes and sizes. One as material the plastics commonly used for film production. In particular to have. Polyethylene tubular films have proven themselves.
Dabei ist zu beachten, daß die Folien bezüglich ihres Brandverhaltens und ihrer elektrischen Eigenschaften den Kunststoff-Prüfbestimmungen des Landesoberbergamtes Nordrhein-Westfalen (Entwurf Juli 1974) entsprechen.It should be noted that the films with regard to their fire behavior and their electrical properties comply with the plastics test regulations of the regional mining authority North Rhine-Westphalia (draft July 1974).
Da die gefüllten Schläuche einen Innendruck von 0,05 bis 0,5 bar aufnehmen müssen und gegen mechanische Beschädigungen von außen sicher sein müssen, ist eine Foliendicke von mindestens 0,5 mm erforderlich.Because the filled hoses absorb an internal pressure of 0.05 to 0.5 bar and must be secure against external mechanical damage is one Foil thickness of at least 0.5 mm required.
Wichtig dabei ist eine gute Dehnbarkeit des Folienmaterials, damit die aufgeblasenen Schläuche sich der Jeweiligen Form des auszufüllenden Raumes anpassen können.It is important that the film material can be stretched so that it can be stretched well the inflated tubes adapt to the respective shape of the space to be filled can.
Zur weiteren Anpassung der Schlauchfolien an die unterschiedlichen Größen und Formen der auszufüllenden Räume können Schlauchfolien in verschiedenen Größen verfügbar sein, wobei die einzelnen Typen zweckmäßig durch entsprechende Färbung gekennzeichnet sind.For further adaptation of the tubular films to the different Sizes and shapes of the spaces to be filled can be tubular films in different Sizes are available, the individual types being expedient by appropriate Coloring are marked.
Das Aufblasen der Schläuche geschieht am einfachsten mittels Preßluft, die über ein Druckminderventil dem Druckluftnetz entnommen werden kann. Nach Erreichen des Fülldrucks von etwa 0,05 bis 0,1 bar liegen die Schlauchfolien dicht am Gebirge und gleichzeitig am Ausbau an, so daß der Ausbau fest mit dem Gebirge verspannt ist. Sollte im Verlauf von einiger Zeit an einzelnen Stellen der Gebirgsdruck zunehmen, kann durch ein zusätzlich an den Schlauchfolien angebrachtes Uberdruckventil ein langsames Entweichen des entstehenden Überdrucks ermöglicht werden, bis sich das Gebirge an den Ausbau anlegt und er direkt vom Ausbau aufgenommen wird.The easiest way to inflate the hoses is by means of compressed air, which can be taken from the compressed air network via a pressure reducing valve. After reaching With a filling pressure of around 0.05 to 0.1 bar, the tubular films are close to the rock and at the same time on the expansion, so that the expansion is firmly braced with the mountains is. Should the mountain pressure increase in individual places over the course of some time, can be activated by a pressure relief valve additionally attached to the tubular films allow the excess pressure to escape slowly until the Mountains attach to the expansion and it is absorbed directly from the expansion.
In: der beiliegenden Abbildung 1 wird ein erfindungsgemäß verfüllter Streckenausbau im Querschnitt dargestellt. Zwischen dem Gebirge 1 und Verzug 2, der durch die Seitensegmente 3 und das Firstsegment 4 gehalten wird, befinden sich die druckluftgefullten Schlauchfolien 5, die sich in ihrer Form dem 3eweiligen Hohlraum angepaßt haben.In: the enclosed Figure 1, a filled according to the invention Line expansion shown in cross section. Between the mountains 1 and delay 2, which is held by the side segments 3 and the ridge segment 4 are located the compressed air-filled tubular films 5, the shape of which corresponds to the 3eweiligen cavity have adapted.
Durch das erfindungsgemäße Verfahren ergibt sich der Vorteil, daß das Verfüllen der Hohlräume zwischen Gebirge und Ausbau schnell und lückenlos erfolgen kann. Außer den Schlauchfolien werden keine weiteren Materialien benötigt, was sowohl transporttechnisch als auch wirtschaftlich günstig ist.The inventive method has the advantage that the filling of the cavities between the mountains and the expansion can be carried out quickly and without gaps can. Apart from the tubular films, no other materials are required, both is favorable in terms of transport as well as economically.
Gegebenenfalls ist auch eine mehrmalige Verwendung der Schlauchfolien möglich.If necessary, the tubular films can also be used several times possible.
