Description
Przy rozsadzaniu wegla lub mineralów kopalnianych nabojami, zawierajacymi la¬ dunek cieklego powietrza lub cieklego tle¬ nu, zdarzaja sie czesto niewypaly, a po wy¬ buchu w spalinach znajduja sie nieraz gazy szkodliwe.Niewypaly i powstawanie gazów szko¬ dliwych zdarzaja sie czesto wtedy, gdy otwór wybuchowy znajduje sie w wilgotnej lub spekanej warstwie.Okazalo sie, ze wady powyzsze mozna usunac przez umieszczenie w naboju sale¬ try sodowej, która mozna zmieszac z wla¬ sciwym ladunkiem naboju lub umiescic od¬ dzielnie w naboju, lub tez przez otoczenie naboju warstwa saletry sodowej.Stwierdzono równiez, ze dodatnie dzia¬ lanie saletry sodowej wzmaga sie, o ile saletra jest bardzo drobno zmielona. PLWhen blasting coal or mine minerals with cartridges containing a charge of liquid air or liquid oxygen, misfires often occur, and after an explosion in the exhaust fumes, there are sometimes harmful gases. Fires and the formation of harmful gases often occur when when the blast hole is in a wet or cracked layer. It has turned out that the above-mentioned defects can be eliminated by placing sodium chloride in the cartridge, which can be mixed with the proper charge of the cartridge or placed separately in the cartridge, or by surrounding the cartridge. Sodium nitrate layer. It has also been found that the positive effect of sodium nitrate is enhanced if the nitrate is very finely ground. PL
