Mu nganda zigezweho, umuyoboro w'icyuma udafite umugozi ni igikoresho cy'ingenzi cy'ingenzi. Imiterere yawo idafite umugozi ituma uba ingenzi mu gutwara amazi, ingufu n'inkunga y'imiterere, bigatuma uhabwa izina ry'ikinyobwa "imitsi y'amaraso y'icyuma" y'isi y'inganda.
Akamaro k'ingenzi k'imiyoboro y'icyuma idahindagurika kari mu miterere yayo y'icyuma ihuriweho. Bitandukanye n'imiyoboro ivanze, isaba gusudira kugira ngo ikore, imiyoboro y'icyuma idahindagurika itunganywa mu buryo butaziguye uhereye ku bipande by'icyuma gikomeye ikajya mu miyoboro y'ubucucike binyuze mu nzira nko gushyuha, gukurura ubukonje, cyangwa gusohora. Ubu buryo bukuraho intege nke zishobora kubaho mu miyoboro ivanze, bigatuma habaho kudakomera kw'umuvuduko, gufunga, no kudahungabana kw'imiterere iyo ihuye n'umuvuduko mwinshi, ubushyuhe bwinshi, ubushyuhe buke, cyangwa ibyuma byangiza. Byaba ari imiyoboro ya peteroli na gazi ikoreshwa kure, imiyoboro y'umwuka ikoresha ubushyuhe bwinshi ku byuma bitanga amashanyarazi, cyangwa ibice by'imiterere by'ikoranabuhanga mu nganda z'indege, imiyoboro y'icyuma idahindagurika ni yo ikundwa cyane bitewe n'imikorere yayo yizewe.
Mu rwego rwo gukora, inzira yo gukora imiyoboro y'icyuma idahindagurika ni nziza kandi iragoye, ahanini igabanyijemo ibice bibiri: gushyushya no gukurura bikonje (gukonjesha). Imiyoboro y'icyuma idahindagurika ikorwa binyuze mu buryo nko gushyushya igice cyo hejuru, gutobora, gukurura no gupima ingano. Igicuruzwa cyarangiye gifite umurambararo munini n'ubugari bw'urukuta bumwe, bigatuma kiba kibereye inyubako nini z'ubuhanga. Imiyoboro y'icyuma idahindagurika ikururwa n'ubukonje, ikomeza gutunganywa no gukurura bikonje nyuma yo gukurura bikonjesha, igera ku buziranenge bwo hejuru no kurangiza neza ubuso. Ikoreshwa cyane mu bikorwa bisaba ubushishozi buhamye, nko mu modoka, imashini, n'ibikoresho by'ubuvuzi.
Imiyoboro y'icyuma idakora neza ikoreshwa mu nzego nyinshi z'ingenzi z'ubukungu bw'igihugu. Mu nganda z'ingufu, ni ingenzi mu gucukura peteroli na gaze no gukwirakwiza imiyoboro, ikabasha kwihanganira igitutu kinini cyo munsi y'ubutaka n'ibidukikije bigoye by'ubutaka. Mu nganda zikora imashini, zitunganywamo ibice by'ingenzi nka spindles z'ibikoresho by'imashini na silindiri za hydraulic, bigamije kohereza ingufu no gukora neza. Mu nganda z'ubwubatsi n'ibikorwa remezo, imiyoboro minini y'icyuma idakora neza ikoreshwa mu byuma bishyigikira inyubako ndende cyane n'inkuta z'ibiraro, bigamije umutekano w'umushinga. Ndetse no mu nganda zigezweho nka aerospace na nuclear, imiyoboro y'icyuma idakora neza ikozwe mu byuma byihariye igumana imikorere ihamye mu gihe cy'imikorere igoye.
Bitewe n’iterambere rihoraho ry’ikoranabuhanga mu nganda, imiyoboro y’icyuma idahindagurika nayo irimo gutera imbere igana ku musaruro mwiza no kunoza kurushaho. Binyuze mu iterambere ry’ibikoresho bishya bya alloy, ingese n’ubushyuhe bwinshi bw’imiyoboro y’icyuma idahindagurika bikomeje gutera imbere. Hakoreshejwe ibikoresho by’ubuhanga mu gukora, ubushobozi bwo kwihanganira ibintu buriyongera, bugahuza n’ibyo inganda zitandukanye zikeneye. Nk’ “imiyoboro y’amaraso y’icyuma” y’urwego rw’inganda, ifite imbaraga n’ubukomere, imiyoboro y’icyuma idahindagurika imaze igihe kinini ari ingenzi cyane mu guteza imbere inganda no kwemeza ko imishinga minini iyubakwa.
