Bey'ad aad u daxalaysa oo ay sababtay saamaynta juquraafigu waxay astaamaynaysaa George Fisher Zinc Mine ee ku yaal gobolka macdanta Mount Isa ee Waqooyiga Australia. Sidaa darteed, milkiilaha, Xstrata Zinc, oo ah shirkad hoos timaada kooxda macdanta ee caalamiga ah ee Xstrata Plc., waxay rabeen inay hubiyaan ilaalinta daxalka iyagoo si buuxda u daboolaya barroosinnada godka qodista inta lagu jiro shaqooyinka wadista.
DSI Australia waxay siisay kiimiko TB2220T1P10R Posimix Bolts ee gundhigga. Dhererkoodu waa 2,200mm waxayna leeyihiin dhexroor 20mm ah. Intii lagu jiray rubuci afraad ee 2007, DSI Australia waxay samaysay imtixaanno kala duwan oo dhammaystiran iyadoo la kaashanaysa goobta Xstrata Zinc. Tijaabada waxaa la sameeyay si loo helo qiyaasta ugu wanaagsan ee suurtogalka ah ee daboolida barroosinnada iyadoo la kala beddelayo cabbirrada ceelasha riigga ah iyo kartoonada xabagta.
Doorashada waxaa laga samayn karaa 1,050mm kartoojyada resin dheer oo leh qaybo dhexdhexaad ah iyo kuwo gaabis ah oo 26mm iyo 30mm dhexroor ah. Markaad isticmaalayso kartoonka 26mm ee ceelasha dhexroorkoodu yahay 35mm ee caadiga u ah nooca barroosinka, waxa la gaadhay heerka koobid 55% ah. Sidaa darteed, laba tijaabo oo kale ayaa la sameeyay.
- Isticmaalka kartridge isku mid ah oo resin ah iyo yaraynta dhexroorka ceelka ilaa dhexroorka ugu yar ee 33mm ayaa lagu gaadhay koobid 80%.
- Haysashada dhexroorka ceelka 35mm iyo isticmaalka kartridge ka weyn oo xabagta leh oo dhexroorkiisu yahay 30mm waxay keentay in la daboolo 87%.
Labada imtixaan ee beddelka ah waxay gaadheen heerka koobabaynta ee macmiilku u baahan yahay. Xstrata Zinc waxay dooratay beddelka 2 sababtoo ah 33mm-dhibcaha laydhka dib looma isticmaali karin sababo la xiriira sifada dhagaxa deegaanka. Intaa waxaa dheer, kharashyada yar yar ee kartridge-yada waaweyn ee xabagta ayaa in ka badan si buuxda loogu magdhabay isticmaalka badan ee 35mm bit.
Kala duwanaanshaha tijaabada ee guusha leh awgeed, DSI Australia waxa la siiyay qandaraas bixinta barroosinnada Posimix iyo 30mm resin cartridges by milkiilaha miinada, Xstrata Zinc.
