Ibidukikije byangirika cyane biterwa n’imiterere ya geologiya biranga ikirombe cya George Fisher Zinc mu karere k’ubucukuzi bw’umusozi wa Isa muri Ositaraliya y'Amajyaruguru. Kubera iyo mpamvu, nyir'ubwite, Xstrata Zinc, ishami ry’itsinda rishinzwe ubucukuzi bw’amabuye y'agaciro Xstrata Plc.
DSI Australiya yatanze imiti TB2220T1P10R Posimix Bolts ya ankorage. Bolt ifite uburebure bwa 2200mm kandi ifite diameter ya 20mm. Mu gihembwe cya kane 2007, DSI Ositaraliya yakoze ibizamini byinshi ku bufatanye na Xstrata Zinc ku rubuga. Igeragezwa ryakozwe kugirango haboneke urugero rwiza rushoboka rwa encapsulation kuri ankeri muguhindura ingano ya borehore na resin cartridges.
Ihitamo rishobora gukorwa kuva 1.050mm z'uburebure bwa resin ya karitsiye hamwe nibice bito kandi bitinda muri 26mm na 30mm. Iyo ukoresheje amakarito ya 26mm muri boreho ya 35mm ya diametre asanzwe kuri ubu bwoko bwa ankeri, urwego rwa encapsulation ya 55% rwagezweho. Kubera iyo mpamvu, hakozwe ibigeragezo bibiri.
- Gukoresha karitsiye imwe ya resin no kugabanya diameter ya borehole kugeza kuri diameter ntoya ya 33mm byageze kuri encapsulation ya 80%.
- Kugumana diameter ya borehole ya 35mm no gukoresha ikarito nini ya resin ifite diameter ya 30mm byaviriyemo enapsulation ya 87%.
Ibizamini byubundi buryo byageze ku ntera ya ensapsulation isabwa n'umukiriya. Xstrata Zinc yahisemo ubundi 2 kuko bits ya 33mm ya drill ntabwo yashoboraga kongera gukoreshwa kubera ibiranga urutare rwaho. Mubyongeyeho, ibiciro biri hejuru cyane ya karitsiye ya resin nini birenze kwishyurwa no gukoresha inshuro nyinshi ya 35mm ya drill bit.
Bitewe nuko ibizamini byagenze neza, DSI Australiya yahawe amasezerano yo gutanga inanga za Posimix hamwe na 30mm ya resin ya resin na nyiri iki kirombe, Xstrata Zinc.
