Description

Naboje wybuchowe do rozsadzania ma¬ terialu kopalnianego posiadaja zwykle o- slony w ksztalcie cylindra, utrudniajace zapalanie sie mieszanin wybuchowych, np. metanu lub pylu weglowego z powietrzem.Oslony te wykonywa sie dotychczas z ma¬ terialów, które dzialaja chlodzaco lub ulat¬ niaja sie w temperaturze wybuchu i tworza powloke ochronna izolujaca ladunek nabo¬ ju od otaczajacego go powietrza.. Jako ta¬ kie materialy stosuje sie sól kuchenna, dwuweglan sodu, fluorek sodu lub wapnia, jodek etylu, kwasny siarczyn sodu; do ma¬ terialów tych dodaje sie srodka wiazacego, np. gliny, dekstryny i t. d. Oslony takie nie izoluja jednak ladunku dostatecznie, a po¬ za tym przy wybuchu wytwarzaja sie gazy trujace, np. S02, i zracy osad, np. NaOH.Dzieki wynalazkowi niniejszemu mozna usunac powyzsze wady przez zastosowanie jako materialu do wyrobu oslon stalego bezwodnika kwasu weglowego samego lub zmieszanego z woda w postaci lodu, przy czym stosunek ilosci bezwodnika kwasu we¬ glowego i wody w mieszaninie moze byc rózny. Oslona taka paruje czesciowo po u- miesizczeniu w otworze wybuchowym, a CO2, którego ciezar wlasciwy jest wiekszy *) Wlascicielka patentu oswiadczyla, iz wynalazca jest Edward Janczyk.<*d ciezaru mieszanin palnych, wypycha te mieszaniny ze szczeliiL otaczajacych otwór wybuchowy, dzidki czemL plomien, powsta¬ jacy przy wybuchu, jest oddzielony odi ga¬ zów otaczajacych nabój. Oprócz tego COz dziala skutecznie jako srodek chlodzacy, a przy wybuchu nie powstaja trujace gazy lub zracy osad. Oslona wedlug wynalazku ni¬ niejszego stanowi cylinder z bezwodnika kwasu weglowego lub jego mieszaniny z woda, otaczajacy ladunek materialu wy¬ buchowego.Oslona wedlug wynalazku niniejszego moze byc stosowana do wszelkich materia¬ lów wybucfcowych uzywanych w górnictwie. PLExplosive cartridges for bursting mine material usually have cylinder-shaped shields that prevent the ignition of explosive mixtures, e.g. methane or coal dust with air. These shields are previously made of materials that have a cooling effect or volatilize. at the explosion temperature and forms a protective coating that isolates the charge of the cartridge from the surrounding air. Common salt, sodium bicarbonate, sodium or calcium fluoride, ethyl iodide, acid sodium sulfite are used as such materials; to these materials, a binding agent is added, e.g. clay, dextrin, etc. Such shields, however, do not insulate the charge sufficiently, and then, in the event of an explosion, poisonous gases, e.g. SO2, are produced and the precipitate, e.g. NaOH, is destroyed. The present invention can overcome the above disadvantages by using solid carbonic anhydride shells either alone or mixed with ice water as the material for the production, the ratio of the amount of carbonic anhydride and water in the mixture may be different. Such a shield evaporates partially after being amalgamated in the blast hole, and CO2, the specific gravity of which is higher *) The patent owner declared that the inventor is Edward Janczyk. the flame which is produced in the event of an explosion is separated from the gases surrounding the cartridge. In addition, COz is effective as a cooling agent, and in the event of an explosion, no poisonous gases or corrosive deposits are formed. The envelope according to the present invention is a cylinder of carbonic anhydride or a mixture thereof with water surrounding the charge of the explosive. The envelope according to the present invention can be used for any type of explosive material used in mining. PL
