Indawo egqwala kakhulu ebangelwa amathonya okwakheka komhlaba iveza Imayini ye-George Fisher Zinc esifundeni sezimayini i-Mount Isa eNyakatho ye-Australia. Ngenxa yalokho, umnikazi, i-Xstrata Zinc, inkampani engaphansi kweqembu lezimayini elisebenza emhlabeni wonke i-Xstrata Plc., wayefuna ukuqinisekisa ukuvikeleka okuhle kokugqwala ngokumboza ngokugcwele kwamahange emgodini wokubhoboza ngesikhathi sokushayela.
I-DSI Australia inikeze ngamakhemikhali i-TB2220T1P10R Posimix Bolts okubamba intambo. Amabhawodi angu-2,200mm ubude futhi anobubanzi obungu-20mm. Ngekota yesine ka-2007, i-DSI Australia yenze uhla lokuhlola olubanzi ngokubambisana ne-Xstrata Zinc esizeni. Ukuhlolwa kwenziwa ukuze kutholwe inani elingcono kakhulu lokuhlanganisa amahange ngokushintsha ubukhulu bemigodi namagobolondo eresin.
Kungenziwa ukukhetha kumakhatriji eresin amade angu-1,050mm anazo zombili izingxenye ezimaphakathi nezinensa kumadayamitha angama-26mm no-30mm. Uma usebenzisa i-cartridge engu-26mm kuma-boreholes obubanzi obungu-35mm ejwayelekile kulolu hlobo lwesikhonkwane, izinga lokuvala elingu-55% lafinyelelwa. Ngenxa yalokho, kwenziwa ezinye izivivinyo ezimbili.
- Ukusebenzisa i-cartridge ye-resin efanayo kanye nokunciphisa ububanzi be-borehole kuya kububanzi obuncane obungu-33mm kuzuze ukugoqa okungama-80%.
- Ukugcina ububanzi bomgodi obungama-35mm kanye nokusebenzisa i-cartridge ye-resin enkulu enobubanzi obungama-30mm kuholele ekuhlanganisweni okungama-87%.
Kokubili okunye ukuhlola kuzuze izinga lokuhlanganisa elidingwa ikhasimende. I-Xstrata Zinc ikhethe enye indlela engu-2 ngenxa yokuthi ama-drill bits angu-33mm awakwazanga ukuphinda asetshenziswe ngenxa yezici zedwala zendawo. Ukwengeza, izindleko eziphakeme kancane zamakhatriji e-resin amakhulu zingaphezu kokunxeshezelwa ngokugcwele ukusetshenziswa okuningi kwe-drill bit engu-35mm.
Ngenxa yohlu lokuhlola oluyimpumelelo, i-DSI Australia yanikezwa inkontileka yokuhlinzekwa kwamahange e-Posimix nama-cartridges e-resin angu-30mm ngumnikazi wemayini, i-Xstrata Zinc.
