Description

Sprengmittel mit flüssiger Sauer stoff quelle erhalten, wie in- dem 'Hauptpatent nachgewiesen ist, durch Zusatz von Wasser oder .Salzlösungen eine hohe Sicherheit gegen die Entzündung von Kohlenstaub und Schlagwetter. Dieser Erfolg läßt sich noch weiter sichern, wenn man gefrorenes Wasser in die Bohrlöcher bringt, welche mit den Sprengpatronen besetzt werden sollen.Disintegrants obtained with a liquid oxygen source, as shown in the main patent is, through the addition of water or .saline solutions, a high level of protection against inflammation of coal dust and firedamp. This success can be secured even further if you put frozen water in the boreholes brings which are to be occupied with the explosive cartridges.

ίο Bei dem Arbeiten mit flüssigen Gasen kann . Eis, wenn es nicht sonst schon vorhanden ist, in der Grube, z. B. durch Eintauchen von kleinen, starken, mit Wasser gefüllten Zylindern, die der Bohrlochweite angepaßt verfügbar sind, leicht erzeugt werden. Anderweit nimmt man zerstampftes Eis, bringt einen Teil der gewünschten Menge wie auch anderseits die entsprechende Länge eines Zylinders von gefrorenem Wasser auf das Bohrlochtiefste, ladet dann mit den Patronen, setzt noch wieder Eis auf und dann den Besatz. Es genügt je nachdem auch vollkommen, wenn zuerst mit den Patronen geladen wird, alsdann Eis' nachgeführt und nunmehr der Besatz. · .ίο When working with liquid gases, you can . Ice, if it is not already there, in the pit, e.g. B. by immersing small, strong cylinders filled with water, which are available adapted to the borehole width, can be easily generated. Otherwise you take crushed ice, bring part of the desired Amount as well as the corresponding length of a cylinder of frozen Water to the depth of the borehole, then reload with the cartridges, put on ice again and then the stock. It Depending on the case, it is also completely sufficient if the cartridges are loaded first, then Ice 'tracked and now the stocking. ·.

Die tiefkaltes, flüssiges Gas der bekannten Arten enthaltenden Patronen erhalten bis zu ihrer Explosion die gefrorene feste Form des Wassers, welche infolge der Explosionswärme dann übergeht in die Zündung von Schlagwetter und Kohlenstaub verhindernden Dampf.The cartridges containing cryogenic liquid gas of the known types receive up to their explosion the frozen solid form of the water, which as a result of the heat of the explosion then turns into the ignition of firedamp and coal dust preventing Steam.
