Nzvimbo inoparadza zvakanyanya inokonzerwa negeological pesvedzero inoratidzira George Fisher Zinc Mine mudunhu reMount Isa mugodhi kuNorth Australia. Nekuda kweizvozvo, muridzi, Xstrata Zinc, mubatsiri weboka remigodhi rinoshanda pasi rose Xstrata Plc., aida kuona kuchengetedzwa kwakanaka kwekuora kuburikidza nekuvharirwa kuzere kwezvibatiso mugomba rekuchera panguva yekutyaira.
DSI Australia yakapa kemikari TB2220T1P10R Posimix Bolts yekumisa. Mabhaudhi akareba 2,200mm uye ane dhayamita 20mm. Muchikamu chechina cha2007, DSI Australia yakaita huwandu hwakawanda hwebvunzo mukubatana neXstrata Zinc pa-saiti. Kuyedzwa kwakaitwa kuti kuwane yakanakisa inogoneka huwandu hwe encapsulation kune anchors nekusiyanisa hukuru hwezvibhorani uye resin cartridges.
Sarudzo yaigona kuitwa kubva pa1,050mm kureba resin cartridges ane ese aripakati uye anononoka zvikamu mu 26mm uye 30mm madhayamita. Paunenge uchishandisa 26mm katuriji mu35mm dhayamita zvibhorani zvakajairwa nemhando yeanchor iyi, dhigirii yekuvharira ye55% yakawanikwa. Naizvozvo, mimwe miedzo miviri yakaitwa.
- Kushandisa katuriji yeresin imwechete uye kudzikisa chibhorani dhayamita kusvika padiki dhayamita ye33mm kwakawana encapsulation ye80%.
- Kuchengeta chibhorani dhayamita ye35mm uye kushandisa katuriji hombe resin ine dhayamita ye30mm zvakakonzera kuvharirwa kwe87%.
Maedzo ese ari maviri akawana dhigirii re encapsulation inodiwa nemutengi. Xstrata Zinc yakasarudza imwe 2 nekuti 33mm drill bits haaikwanisa kushandiswa zvakare nekuda kwehunhu hwematombo enzvimbo. Pamusoro pezvo, mari yakakwira zvishoma yemakaturiji makuru eresin inopfuura kubhadharwa zvizere nekushandiswa kwakawanda kwe35mm drill bit.
Nekuda kwekuyedza kwakabudirira, DSI Australia yakapihwa kondirakiti yekupihwa kwePosimix anchors uye 30mm resin cartridges nemuridzi wemugodhi, Xstrata Zinc.
