Bestimmte physikalische und chemische Eigenschaften der Deponien sind h\u00e4ufig erforderlich, um das geotechnische und geochemische Verhalten der gro\u00dfen Deponien besser zu verstehen und den potenziellen Mineralwert zu bewerten. Sonic Drilling erm\u00f6glicht das Sammeln hoch repr\u00e4sentativer Proben und eine hervorragende Probenr\u00fcckgewinnung. Diese Bohrmethode wurde zur Wiedererkundung von Deponien, R\u00fcckst\u00e4nden und Haufenlaugkissen verwendet.<\/p>\n<p class=\"p_tc\"><br>Altgesteinskippen bestehen haupts\u00e4chlich aus nicht festem Material - und es ist oft schwierig zu wissen, wie tief sie sind oder welche Arten von Material sie enthalten - was zu Bohrproblemen f\u00fchren kann. Die Sonic-Technologie bietet eine L\u00f6sung, indem sie in-situ Kernproben zu 100 Prozent bei unterschiedlichen Bodenbedingungen produzieren kann.<\/p>\n<\/div><div  class=\"tcvpb-image\" ><img decoding=\"async\" src=\"https:\/\/www.boartlongyear.com\/wp-content\/uploads\/sonic-drilling-depth-record-quote.svg\"><\/div><h2  ><span>Die Herausforderung<\/span><\/h2><div  class=\"\" >\n<p class=\"p_tc\"><a href=\"https:\/\/www.boartlongyear.com\/de\/drilling-services\/surface\/sonic\/\" target=\"_blank\" rel=\"noopener noreferrer\">Boart Longyear Bohrdienstleistungen<\/a> Die Herausforderung bestand darin, Kernproben aus der nicht verfestigten Halde der Kennecott Utah Copper&#039;s Bingham Canyon Mine zu bohren. Die Absicht der Bohrungen bestand darin, den Inhalt der M\u00fcllhalde festzulegen. Die M\u00fcllhalde bestand aus Gesteinsprengstoff mit einem Durchmesser von 254 bis 304,8 Millimeter (10 bis 12 Zoll) und bestand haupts\u00e4chlich aus Porphyr-Ablagerungen (Granit-artigen Gesteinen).<\/p>\n<p class=\"p_tc\">Mit einer gezielten Tiefe von 213,36 Metern (700 ft) bestand das Hauptziel darin, eine detaillierte kontinuierliche Probe des Abraums f\u00fcr Abraumgestein zu liefern und die Felsbrocken zu best\u00e4tigen. Boart Longyear musste auch Piezometer (Wasserstandsmessger\u00e4te) und Lysimeter (Feuchtigkeitsmessger\u00e4te) installieren. Geotechnische Proben m\u00fcssten auch alle 6,096 Meter (20 Fu\u00df) entnommen werden, um die Stabilit\u00e4t und den Feuchtigkeitsgehalt der ersten 60,96 Meter (200 Fu\u00df) zu best\u00e4tigen.<\/p>\n<\/div><h2  ><span>Die L\u00f6sung<\/span><\/h2><div  class=\"\" >\n<p class=\"p_tc\"><a href=\"https:\/\/www.boartlongyear.com\/de\/drilling-services\/surface\/sonic\/\" target=\"_blank\" rel=\"noopener noreferrer\">Sonic Bohren<\/a> ist die perfekte Methode f\u00fcr das Bohren in unkonsolidiertem Material, wie z.

F\u00fcr die ersten 106,68 Meter bohrten sie ein Bohrloch von 228,6 Millimeter (9 Zoll), w\u00e4hrend sie alle 6,096 Meter (20 Fu\u00df) den Bohrstrang stie\u00dfen, um eine geotechnische Spaltl\u00f6ffelprobe f\u00fcr die ersten 60,96 Meter (200 Fu\u00df) zu ziehen.<\/p>\n<p class=\"p_tc\">F\u00fcr die zweite Stufe bohrte das Team mit einem Bohrer von 203,2 Millimeter (8 Zoll) mit Geh\u00e4use auf 152,4 Meter (500 Fu\u00df). Sie bewegten sich tiefer auf 228,6 Meter (750 Fu\u00df) und verwendeten f\u00fcr die dritte Stufe ein 177,8-Millimeter-Bit mit Geh\u00e4use. Die Bohrer \u00fcbertrafen ihre angestrebte Bohrtiefe von 213,36 Metern (700 ft) noch immer nicht in der Gesteinsformation.<\/p>\n<\/div><div  class=\"\" >\n<p class=\"p_tc\">Boart Longyear musste die wahre Tiefe der M\u00fcllhalde finden und f\u00fchlte sich so, als h\u00e4tte das Bohrger\u00e4t noch die F\u00e4higkeit und den R\u00fcckzug, tiefer zu gehen. Sie wurden mit einem 152,4-Millimeter-Bohrer mit Geh\u00e4use auf 264,261 Meter gebohrt. Die letzte Stufe konnte nicht mit Geh\u00e4use gebohrt werden, da sie zu einem 101,6-Millimeter-Bohrloch (4 Zoll) bewegt werden mussten. Sie lie\u00dfen nur noch den letzten Schritt auf 274,32 Meter (900 ft) - und stellten einen neuen Boart Longyear-Rekord f\u00fcr Schallbohrungen auf - sie erreichten eine um 28 Prozent gr\u00f6\u00dfere Tiefe als urspr\u00fcnglich geplant.<\/p>\n<p class=\"p_tc\">Es dauerte 16 Schichten von 12 Stunden (192 Stunden), um die neue Rekordtiefe f\u00fcr Schallbohrungen zu erreichen. Boart Longyear verlor zwei dieser Schichten (24 Stunden) durch Regen. Eine weitere wichtige Errungenschaft war, dass die gesamte Tiefe durch trockenes Bohren erreicht wurde und 100% In-Situ-Kernproben bei einer Lochabweichung von weniger als 1% erreicht wurden.<\/p>\n<\/div><\/div><\/div><\/div>\n\t\t\n\t\t\n\t<\/section><section class=\"tcvpb_section_tc boilerplate\">\n\t\t\n\t\t<div class=\"tcvpb_section_content\"><div class=\"tcvpb_container\"><div class=\"tcvpb_column_tc_span12\"><div  class=\"\" >\n<p class=\"p_tc\"><strong>Kennecott Kupfermine<\/strong><\/p>\n<p class=\"p_tc\">Die Utah Copper Company wurde 1903 gegr\u00fcndet und die Massenproduktion begann 1906.
