 Gallerton sind auch pflanzliche Leime, wie   Rohstärke, geeignet. Eino sehr   geeignete Breimasse entsteht auch, wenn man zu Chlormagnesium oder Chlorkalziumlauge Alkalien oder 
 EMI2.1 
 



   Versuche in der Grube haben   gezeigt, dass   die Umsetzung der Breie in Karbonate erst nach Monaten eintritt. 
 EMI2.2 
 Laugen von Chormagnesium oder Chlorkalzium durch Zumischung von Stoffen, welche die hygroskopischen Eigenschaften der Laugen nicht zerstören, in klebriger Breiform aufbringt, um grosse Feuchtigkeitsmengen auf den Streckenwandungen für lange Zeit aufspeichern zu können und um eine klebrige Masse zur Abbindung des Kohlenstaubes zu erhalten, wobei, falls erforderlich, eine Vor- oder Nachberieselung der Streckenwandungen mit reiner Lauge vorgenommen werden kann.

 Gall clays, vegetable glues such as raw starch are also suitable. A very suitable pulp is also produced if you add alkalis or chlorine magnesium or calcium chloride
 EMI2.1
 



   Tests in the pit have shown that the conversion of the pulps into carbonates only takes months.
 EMI2.2
 Lye of magnesium chloride or calcium chloride by adding substances that do not destroy the hygroscopic properties of the lyes, applied in sticky pulp form in order to be able to store large amounts of moisture on the route walls for a long time and to obtain a sticky mass to bind the coal dust, whereby, If necessary, the route walls can be pre- or post-sprinkled with pure lye.
