Description

Verfahren zur Herstellung ummantelter Wettersprengstoffe mit erhöhter Leistung oder mit erhöhter Schlagwettersicherheit Es ist bekannt, daß zur Erreichung einer höheren Schlagwettersicherheit Sprengstoffe in Form von Patronen teilweise oder allseitig mit inerten Substanzen oder einem schwachen Sprengstoff umhüllt werden. Hierbei wurde so verfahren, daß die bekannten gelatinösen leistungsstärkeren Wettersprengstoffe mit einem sehr schwachen Sprengstoff ummantelt wurden. Dieser Mantelsprengstoff bestand zu 90 % aus inerter Substanz, z. B. Steinsalz oder Tonerde, und zu 10 % aus Sprengöl, trug also zur Gesamtleistung nur unwesentlich bei.Process for the production of jacketed weather explosives with increased Performance or with increased fire weather security It is known that to achieve a higher firedamp safety explosives in the form of cartridges partially or enveloped on all sides with inert substances or a weak explosive. The procedure here was such that the known, gelatinous, more powerful weather explosives were encased in a very weak explosive. This shell explosive consisted of 90% inert substance, e.g. B. rock salt or clay, and 10% made of explosive oil, so contributed only negligibly to the overall performance.

Erfindungsgemäß wird nun die Leistung der bisher bekannten ummantelten Wettersprengstoffe bei annähernd gleicher Schlagwettersicherheit dadurch erhöht, daß man an Stelle des bisherigen Mantelsprengstoffes einen wesentlich stärkeren, aber auch sehr schlagwettersicheren Sprengstoff, der als Salzpaar Salpeter-Ammonchlorid enthält, nimmt, und zwar von folgender Zusammensetzung: 10 % Sprengöl, 0,5 0/a Holzmehl, 34,5 %- Ammonchlorid, 0,5 0/a Tonerde, 54,5 % Natronsalpeter.According to the invention, the performance of the previously known sheathed Weather explosives are increased with almost the same firedamp security, that instead of the previous shell explosive, a much stronger, but also very fire-proof explosive, the saltpeter-ammonium chloride as a pair of salts contains, takes, of the following composition: 10% explosive oil, 0.5 0 / a wood flour, 34.5% - ammonium chloride, 0.5% alumina, 54.5% sodium nitrate.

Während bisher der Mantelsprengstoff mit nur etwa 5 mt/Liter zur Gesamtleistung beitrug, beträgt der Leistungsanteil bei dem angegebenen neuen Mantelsprengstoff bis 40 mt/Liter.While so far the shell explosives with only about 5 mt / liter to the total output contributed, is the performance share for the specified new shell explosives up to 40 mt / liter.

Ferner kann aber auch erfindungsgemäß ein Sprengstoff, der das Salzpaar Salpeter-Ammon chlorid enthält und noch eine verstärktere Leistung besitzt, als Kernsprengstoff angewendet werden. Die Zusammensetzung dieses Sprengstoffes ist wie folgt: 11% Sprengöl, 30/9 Holzmehl, 32,41/o Ammonchlorid, 2% Trinitrotoluol, 51,6 0/a Natronsalpeter. Dieser Sprengstoff hat die gleiche Leistung wie die bisherigen gelatinösen Wettersprengstoffe, unterscheidet sich von diesen jedoch wesentlich in der Schlagwettersicherheit, da diese erheblich größer ist. Wird dieser Kernsprengstoff mit einem normalen Mantelsprengstoff umhüllt, so erhält man jetzt durch diese Sprengstoffkombination einen schlagwettersicheren Sprengstoff, der zwar bezüglich Leistung sich von den früheren nicht unterscheidet, dagegen bezüglich Schlagwettersicherheit einen wesentlich größeren Beitrag aufweist. Während bisher bei den umhüllten gelatinösen Sprengstoffen bereits drei Patronen genügten, um eine Zündung des Methan-Luft-Gemisches hervorzurufen, sind bei dieser neuen Mantelkombination mehr als zehn Patronen erforderlich, um eine Zündung auszulösen. Die Beispiele zeigen einmal die erhöhte Leistung und zum anderen die erhöhte Schlagwettersicherheit, wobei zum Vergleich die Daten des bisherigen Wetternobelits B (M) 1 angegeben werden. Der Kern dieses Sprengstoffes hat folgende Zusammensetzung: 30 0/0 gelatinöses Sprengöl, 3 % Kalksalpeterlösung, 40 0/0 Steinsalz, 0,5 0/a Holzmehl, 26,5 % Ammonsalpeter. Als Mantelsprengstoff dient hierbei: 10%Sprengöl, 65 0/a Steinsalz, 25 % Natriumbicarbonat.Furthermore, according to the invention, an explosive containing the salt pair Contains nitric ammonium chloride and has an even stronger performance than Nuclear explosives are used. The composition of this explosive is as follows: 11% blasting oil, 30/9 wood flour, 32.41 / o ammonium chloride, 2% trinitrotoluene, 51.6 0 / a sodium nitrate. This explosive has the same performance as the previous ones gelatinous weather explosives, but differs significantly from them in firedamp safety, as this is considerably greater. Will this nuclear explosive enveloped with a normal shell explosive, this is how you get this combination of explosives a firedamp-proof explosive that differs from the earlier no different, on the other hand, in terms of firedamp safety, one significantly has a larger contribution. While so far with the encased gelatinous explosives three cartridges were enough to ignite the methane-air mixture, more than ten cartridges are required for this new jacket combination trigger an ignition. The examples show once the increased performance and for others the increased protection against firedamp, with the data of the previous one for comparison Weather obelits B (M) 1 are given. The core of this explosive is as follows Composition: 30 0/0 gelatinous blasting oil, 3% calcium nitrate solution, 40 0/0 rock salt, 0.5% wood flour, 26.5% ammonium nitrate. The shell explosives used here are: 10% explosive oil, 65 0 / a rock salt, 25% sodium bicarbonate.

Die Leistung dieser Mantelkombination beträgt 35 mt/Liter. Seine Schlagwettersicherheit in der Mörserkante drei Patronen (375 g).The output of this jacket combination is 35 mt / liter. Its firedamp safety three cartridges (375 g) in the edge of the mortar.

B e i s p i.e 1 1 (erhöhte Leistung) Als Kernsprengstoff findet der Kern des Wetternobelits B (M) 1, wie oben angegeben, Verwendung. Mantelsprengstoff: 10 % Sprengöl, 0,5 %- Tonerde, 0,5 % Holzmehl, 55 %, Natronsalpeter, 34 % Arnmonchlorid.B e i s p i.e 1 1 (increased performance) Core of the weather obelite B (M) 1, as stated above, use. Shell explosives: 10% blasting oil, 0.5% clay, 0.5% wood flour, 55% sodium nitrate, 34% ammonium chloride.

Leistung 50 mt/Liter; Schlagwettersicherheit in der Mörserkante: drei Patronen (375 g).Output 50 mt / liter; Firedamp safety in the mortar edge: three Cartridges (375 g).

B e i s p i e 1 2 (erhöhte Schlagwettersicherheit) Kernsprengstoff: 11 % gelatinöses Sprengöl, 2 0/0 Trinitrotoluol, 3 % Holzmehl, 51,6 % Natronsalpeter, 32,4 0/a Ammonchlorid.EXAMPLE 1 2 (increased firedamp resistance) Nuclear explosive: 11% gelatinous blasting oil, 2 0/0 trinitrotoluene, 3% wood flour, 51.6% sodium nitrate, 32.4% ammonium chloride.

Mantelsprengstoff: 10°/o Sprengöl, 21/o Tonerde, 88 0/a Steinsalz.Shell explosives: 10 per cent blasting oil, 21 per cent clay, 88 per cent rock salt.

Leistung 73 mt/Liter.Output 73 mt / liter.

Die gesamte Leistung des Mantelsprengstoffes beträgt 38 mt/Liter, liegt also sogar etwas höher als bei dem bisherigen ummantelten Sprengstoff Nobelit B (M) 1. Schlagwettersicherheit in der Mörserkante: zehn bis elf Patronen.The total output of the shell explosive is 38 mt / liter, is therefore even slightly higher than with the previous encased explosive nobelite B (M) 1. Firedamp protection in the mortar edge: ten to eleven cartridges.
