Verfahren zum Dichtmachen und Verfestigen von Bergeversatz.
Nach der Erfindung gemäss Patent Nr. 69045 wird der von den Schlämmwässern aufgeführte Schlamm durch gleichzeitige Zugabe gerinnend wirkender Substanzen zur Ausscheidung gebracht. Diese Erscheinung lässt sich mit Vorteil zur Herstellung dichter und standfester Versätze oder zum Dichtmachen eines schon bestehenden Versatzes beim Bergbaubetriebe anwenden.
Beim Schlämmversatzverfahren ist es bei Anwendung des zu Gebote stehenden Versatzmateriales unmöglich, einen wirklich dichten Versatz, der wasser-und wetterundurchlässig ist und nicht abrollt, herzustellen. Ein Dichtmachen durch einfaches Beimischen von lehmigen, tonigen Substanzen oder dgl. zum Versatzmateriale gelingt aus dem Grunde nicht, weil durch die Verteilung von Kolloidstoffen im Wasser ein Absetzen des Schlammes hintangehalten wird. Es werden daher diese tonigen Substanzen durch das Wasser einfach weggespült und können sonach nicht zur Abdichtung beitragen. Anders ist es jedoch, wenn man das Zumischen solcher, Kolloidstoffe enthaltender Materialien unter gleichzeitiger Zugabe gerinnend wirkender Substanzen vornimmt.
Durch das Gerinnen der Kolloidstoffe findet dann in dem zu versetzenden Raume ein Absetzen der tonigen Substanzen statt, die sonst, wie erwähnt, vom Schlämmwasser mitfortgerissen werden. Es wirkt in diesem Falle der an und für sich nicht dichte Versatz wie ein Filter, welches von den ausgeflockten Schlarulllteilchen verstopft und dadurch vollständig dicht, wasser- und wetterundurchlässig gemacht aud ausserdem verfestigt wird.
Je nach den Verhältnissen wird es sich empfehlen, das Zumischen des tonigen, KoDoidstoSe enthaltenden Materiales und der gerinnend wirkenden Substanz gleichzeitig mit dem Einschlämmen des Versatzmateriales oder ein absatzweises Schlämmen in der Art vorzunehmen, dass zuerst normal geschlämmt und darn die mit der gerinnend wirkenden Substanz vermengte, Kolloidstoffe f1hrende Trübe darübergeleitet wird.

Process for sealing and consolidating rock backfill.
According to the invention according to patent no. 69045, the sludge carried by the sludge waters is caused to be excreted by simultaneous addition of coagulating substances. This phenomenon can be used to advantage for producing dense and stable offsets or for sealing an already existing offset in mining operations.
When using the available backfill material, it is impossible to produce a really tight backfill that is impermeable to water and weather and does not roll off. Sealing by simply adding loamy, clayey substances or the like to the backfill material does not succeed for the reason that the sludge is prevented from settling through the distribution of colloid substances in the water. These clayey substances are therefore simply washed away by the water and can therefore not contribute to the sealing. It is different, however, when such materials containing colloidal substances are mixed in with the simultaneous addition of coagulating substances.
The coagulation of the colloidal substances then causes the clayey substances to settle in the space to be moved, which otherwise, as mentioned, are carried away by the muddy water. In this case, the in and for itself not dense offset acts like a filter, which is clogged by the flocculated Schlarulll particles and thereby made completely impermeable to water and weather and also solidified.
Depending on the circumstances, it will be advisable to mix in the clayey, codoid-containing material and the coagulating substance at the same time as the sludging of the backfill material or to carry out intermittent sludging in such a way that initially normally sludged and then the coagulated substance is mixed , Turbidity containing colloids is passed over it.
The novelty of the process is that there are no holloid substances

The parts of the procedure consist of:
1. In the sealing of the offset to prevent penetration of water and weather,
EMI1.2
the sludge backfill generated dangerous effects on the daily upper lacho.
