Umsebenzi oyinhloko weumshini wokudubulaukususa ama-burrs kanye nokugqwala ebusweni bomkhiqizo wensimbi, noma okunye ukungcola okunamathiselwe ebusweni bomkhiqizo wensimbi. Umshini wokuqhumisa isibhamu usewubuchwepheshe obuhle kakhulu bokwelashwa kwendawo kanye nomshini osebenza kahle kakhulu ekukhiqizeni insimbi, ngakho-ke umshini wokudubula usetshenziswa kabanzi ekukhiqizeni insimbi.
Ngaphandle kobuchwepheshe obuhle bokwelapha ubuso, umshini wokudubula oqhumayo ungasusa futhi imikhiqizo ethile enokungcola okungathí sina okunamathiselwe phezulu, futhi uqhubeke uqinisa imiphumela yokwelashwa okungaphezulu ngokwezidingo zokukhiqiza, ukuze Umphumela wokwelashwa kwendawo uqinisekiswe.
Umsebenzi omkhulu wokudubula umshini wokudubula ekukhiqizeni izimboni ukwelapha ubuso bemikhiqizo yensimbi, futhi ngasikhathi sinye, kunganciphisa impilo yokukhathala kwezingxenye, kwandise ukucindezeleka okuhlukahlukene kwendawo, futhi kungashiwo ukuthi ukwandisa amandla izingxenye zomkhiqizo, ezivumela imikhiqizo yensimbi Ukwelashwa okungaphezulu kuphelele kakhulu, futhi ubuso obumpofu begrit yensimbi nesibhamu sensimbi kungabuye kuhlolwe umshini wokudubula.
