Igihe cy'itumba kiraza tutabizi, kandi biteganijwe ko tuzatangira gushyushya uku kwezi.Muri icyo gihe, uruganda rukora ibyuma narwo rwabonye integuza y’ibidukikije, kandi gutunganya ibyo aribyo byose, nibindi, bigomba guhagarikwa, nka: gusiga irangi ryicyuma kidafite icyuma, gushushanya ibyuma bidafite icyuma, kwagura imiyoboro idafite ibyuma, nibindi, nibindi birimo icyuma kidafite icyuma kirwanya ruswa, icyuma kitagira umuringa cyumusenyi, icyuma kitagira icyuma gisukuye, gufata ibyuma bidafite icyuma, nibindi, bigomba kugenwa hakurikijwe ibyo umukiriya asabwa.Niba wihutiye gukoresha no kwakira ibicuruzwa mugihe cya vuba, nyamuneka ubimenyeshe kandi utegure kandi usubize mbere.
intangiriro y'ibanze:

Umuyoboro w'icyumani umurongo muremure wibyuma bifite igice cyambaye ubusa kandi nta kizingiti kizengurutse.Ikozwe mu byuma cyangwa ibyuma bikomeye bitobora binyuze mu gutobora hanyuma bigashyirwa hejuru, bikonje cyangwa bikonje.

Umuyoboro w'icyuma udakoreshwa:

Gukoresha imiyoboro idafite ibyuma byerekana cyane cyane imirima itatu yingenzi.Imwe ni ikibanza cyubwubatsi, gishobora gukoreshwa mubutakaumuyoboroubwikorezi, harimo gukuramo amazi yubutaka mugihe wubaka inyubako.Iya kabiri ni ikibanza cyo gutunganya, gishobora gukoreshwa murigutunganya imashini, kwikorera amaboko, nibindi. Icya gatatu ni umurima w'amashanyarazi, harimoimiyoboroyohereza gaze, imiyoboro y'amazi yo kubyara amashanyarazi, nibindi.

Kurugero, imiyoboro yicyuma idakoreshwa ikoreshwa muburyo, gutwara amazi,icyuka giciriritse kandi giciriritse, amashyanyarazi menshi, ibikoresho by'ifumbire, gucamo peteroli, gucukura geologiya, gucukura diyama,gucukura amavuta, amato, ibinyabiziga igice cya shaft, moteri ya mazutu, nibindi. Gukoresha imiyoboro yicyuma idafite icyuma birashobora kwirinda ibibazo nko kumeneka, kwemeza ingaruka zikoreshwa, no kunoza imikoreshereze yibikoresho.
