Description

Sprengverfahren Es ist an sich bekannt, Sprengkörper zu verwenden, die aus einem geschlossenen Druckgefäß bestehen, in dem sich gepreßte Gase, gegebenenfalls in flüssigem Zustande, befinden, deren Expansion durch eine plötzlich starke Wärme entwickelnde chemische Reaktion, wie die Thermitreaktion, ausgelöst wird. Da sich hierbei die gepreßten Gase in einem starken Druckgefäß befinden, das in einer mit einer Zündkapsel versehenen aluminothermischen Mischung eingebettet ist, ist seine vorzeitige Explosion bei unvorsichtiger Handhabung nicht ausgeschlossen. Demgegenüber besteht das den Gegenstand der Erfindung bildende Sprengverfahren darin, daß man Mischungen von Aluminium mit Metalloxyden mit Wasser zusammenbringt, das leicht verdampft, und zwar benutzt man in bekannter Weise zum Verdampfen des Wassers die Wärme, welche entsteht, wenn die Mischungen durch Entzündung zur chemischen Umsetzung kommen. Man ordnet diese Mischungen, welche sich in einer wasserdichten Hülse befinden und gleichzeitig im Innern eine Zündvorrichtung enthalten, im Bohrloch an und bringt neben sie das Wasser. Im übrigen verfährt man wie beim Sprengen mit Sprengstoffen, d. h. man besetzt nach Einbringung der Ladung mit Lehm, Letten oder sonst dem vorliegenden Zweck am besten entsprechenden Besatzmaterial. Im Falle, daß die Richtung der Bohrlöcher das Ausfließen des Wassers zulassen sollte, kann man das Wasser auch in einen Beutel aus Pergamentpapier unterbringen oder aber von einem porösen Stoff, wie Kieselgur, Moos u. dgl., aufsaugen lassen. Bringt man nun die in dem Metalloxydalttminium befindliche Zündpille zur Entzündung, so setzt sich diese Mischung, wie bekannt, unter Entbindung hoher Wärmemengen um, und diese genügen, um das daneben angeordnete Wasser zu verdampfen und zu überhitzen. Der entstehende Dampfdruck zersprengt die Bohrlochwandungen. Um die Umsetzung der Mischung zu beschleunigen, kann man ihr in bekannter Weise einigeProzente eines Sauerstoff abgebenden Salzes, z. B. Kaliumperchlorat, zusetzen, wobei jedoch zu beachten ist, daß dieser letztere Zusatz keineswegs so groß ist, daß obige Mischung den Charakter eines Explosivstoffes erhält.Explosive methods It is known per se to use explosive devices which consist of a closed pressure vessel in which compressed gases, if necessary in a liquid state, their expansion by a sudden strong heat developing chemical reaction, such as the thermite reaction, is triggered. That I in this case, the compressed gases are in a strong pressure vessel, which is in a with is embedded in an aluminothermic mixture provided with a primer, is his premature explosion in case of careless handling cannot be excluded. In contrast the blasting process forming the subject of the invention consists in that one Mixtures of aluminum with metal oxides with water that easily evaporated, and that is used in a known manner to evaporate the water Heat, which arises when the mixtures by ignition to chemical conversion come. You arrange these mixtures, which are in a watertight sleeve and at the same time contain an ignition device inside, in the borehole and brings next to them the water. Otherwise the procedure is the same as for blasting with explosives, d. H. after the cargo has been brought in, one occupies with clay, Latvians or whatever else is at hand Best appropriate trim material for the purpose. In the event that the direction of the drill holes If the water should be allowed to flow out, the water can also be put in a bag made of parchment paper or of a porous material such as diatomaceous earth, Let moss and the like soak up. If you now bring the one located in the metal oxide minium Primer to ignite, so this mixture, as is known, sets itself up with delivery high amounts of heat, and these are sufficient to evaporate the water arranged next to it and overheat. The resulting vapor pressure bursts the walls of the borehole. In order to accelerate the implementation of the mixture, it can be used in a known manner some percent of an oxygen donating salt, e.g. B. potassium perchlorate, add, it should be noted, however, that this latter addition is by no means so great, that the above mixture has the character of an explosive.

Das Wesentliche des Verfahrens ist, daß unabhängig und getrennt nebeneinander in dem Bohrloch sowohl die Mischung mit der Zündvorrichtung einerseits als auch das Wasser anderseits untergebracht werden. Das neue Sprengverfahren zeichnet sich demgemäß vor allem gegenüber allen bekannten Vorgängen dadurch aus, daß die zur Ausführung des Verfahrens erforderlichen Stoffe vollständig handhabungssicher sind. Man hat einerseits die Mischung, die unexplosiv ist, und anderseits Wasser. Demgegenüber bietet der Transport der Sprengstoffe von der Herstellungsstelle bis zum Unterbringen im Bohrloch zahlreiche Gefahren, über die die Unfallstatistik aller Länder jedes Jahr reichliche Belege bietet. Selbst Sprengstoffe, die auf Verwendung flüssiger Luft beruhen, sind hiervon nicht ausgenommen; denn obwohl bei ihnen die Transportgefahren nicht bestehen, werden sie in dem Moment handhabungsunsicher, in welchem sie am Ort hergestellt oder im Bohrloch untergebracht werden, weil es sich eben von dem Moment an, wo die Kohlenstoffträger mit flüssiger Luft getränkt sind, ebenfalls um sogar sehr reibungs- und stoßempfindliche Stoffe, mit anderen Worten, um richtige Sprengstoffe handelt.The essence of the process is that it is independent and separate side by side in the borehole both the mixture with the ignition device on the one hand and the water can be accommodated on the other hand. The new blasting process stands out accordingly above all in relation to all known processes in that the for The substances required to carry out the procedure are completely safe to handle. On the one hand you have the mixture, which is non-explosive, and on the other hand water. In contrast provides the transport of explosives from the place of manufacture to their storage in the borehole numerous dangers, about which the accident statistics of all countries each Year offers ample evidence. Even explosives that are based on use liquid Based on air are not exempt from this; because although with them the transport dangers do not pass, they become insecure in handling at the moment in which they are on Place made or be housed in the borehole because of it from the moment when the carbon carriers are soaked with liquid air are also very sensitive to friction and shock with others Words that real explosives are involved.
