Izici zokubunjwa kwamatshe aqinile njenge-granite kanye nengozi yokwakhiwa kwemigodi. Lapho uklama isisekelo senqwaba yamabhuloho amaningi amakhulu, izinqwaba zidingeka ukuthi zingene edwaleni eliqinile eliqinile kuze kube sekujuleni okuthile, futhi ububanzi bezinqwaba eziklanyelwe lezi zisekelo zenqwaba zingaphezu kuka-1.5mm. Ngisho kuze kufike ku-2m. Ukubhoboza amatshe aqinile anobubanzi obukhulu kangaka kubeka izidingo eziphezulu kumandla wemishini nokucindezela, ngokuvamile kudinga i-torque engaphezu kuka-280kN.m okokusebenza. Lapho ubhoboza kulolu hlobo lokubunjwa, ukulahlekelwa kwamazinyo okubhoboza kukhulu kakhulu, futhi izidingo eziphakeme zibekwe ekuphikiseni ukudlidliza kwemishini.
Indlela yokwakha yokumba i-rotary isetshenziswa ekwakhiweni kwamatshe aqinile njenge-granite ne-sandstone. Izinyathelo kufanele zithathwe kulawa maphuzu alandelayo ukuze kuthuthukiswe ukusebenza kahle kwembobo nokunciphisa izingozi.
(1) Izinto ezisetshenziswayo ezinamandla angu-280kN.m nangaphezulu kufanele zikhethelwe ukwakhiwa kokumba. Lungiselela amazinyo okubhoboza ngobulukhuni obuphakeme nokusebenza kangcono kokugaya kusenesikhathi. Amanzi kufanele engezwe ekwakhekeni kwe-anhydrous ukunciphisa ukuguga kwamazinyo okubhoboza.
(2) Lungiselela kahle amathuluzi okumba. Lapho ubhoboza izimbobo zezinqwaba ezinobubanzi obukhulu kulolu hlobo lokubunjwa, indlela yokumba esezingeni kufanele ikhethwe. Esigabeni sokuqala, i-drill yomphongolo eyandisiwe enobubanzi obuyi-600mm ~ 800mm kufanele ikhethwe ukuze ikhiphe ngokuqondile ingqikithi futhi idale ubuso obukhululekile; noma i-diameter spiral drill encane kufanele ikhethwe ukubhoboza ukudala ubuso obukhululekile.
(3) Lapho izimbobo ezigobile zenzeka ochungechungeni lwamadwala aqinile, kuba nzima kakhulu ukushanela izimbobo. Ngakho-ke, lapho uhlangana nedwala elithambekile, kufanele lilungiswe ngaphambi kokuthi ukubhola kuqhubeke ngendlela evamile.
