Lokhu okubizwa ngokuthi ukujikeleza okuphambene kusho ukuthi lapho umshini wokubhoboza usebenza, idiski ejikelezayo iqhuba i-drill bit ekugcineni kwepayipi lokubhoboza ukuze isike futhi iphule idwala nomhlabathi emgodini. Uketshezi lokubhoboza lugeleza phansi emgodini lusuka endaweni evulekile phakathi kwepayipi lokubhoboza nodonga lwembobo, lupholise i-drill bit, luthwale idwala elisikiwe kanye ne-slag yokubhoboza inhlabathi, bese lubuyela emhlabathini lusuka emgodini wangaphakathi wepayipi lokubhoboza. Ngesikhathi esifanayo, uketshezi lokubhoboza lubuyela emgodini ukuze lwakhe ukujikeleza. Ngenxa yokuthi imbobo yangaphakathi yepayipi lokubhoboza incane kakhulu kunobubanzi bomgodi ongaphansi, isivinini esikhuphukayo samanzi odaka epayipini lokubhoboza sishesha kakhulu kunesokujikeleza okuhle. Akuwona amanzi ahlanzekile kuphela, kodwa futhi i-slag yokubhoboza ingalethwa phezulu kwepayipi lokubhoboza bese igeleza iye ethangini lokudaka. Udaka lungaphinde lusetshenziswe ngemva kokuhlanzwa.
Uma kuqhathaniswa nokujikeleza okuhle, ukujikeleza okuphambene kunezinzuzo zesivinini sokubhoboza esisheshayo kakhulu, udaka oluncane oludingekayo, amandla amancane asetshenziswa yitafula elijikelezayo, isikhathi sokuhlanza imigodi esisheshayo, kanye nokusetshenziswa kwezingcezu ezikhethekile ukubhoboza nokumba amatshe.
Ukubhoboza ukujikeleza okungemuva kungahlukaniswa kube ukubhoboza ukujikeleza okungemuva kwegesi, ukufuthwa kwepompo ukubhoboza okungemuva kanye nokubhoboza ukujikeleza okungemuva kwejethi ngokwendlela yokudlulisa uketshezi olujikelezayo, umthombo wamandla kanye nomgomo wokusebenza. Ukubhoboza ukujikeleza okungemuva kwegesi okuphakanyisiwe kwaziwa nangokuthi ukubhoboza ukujikeleza okungemuva kwengcindezi yomoya, futhi umgomo wayo wokusebenza umi kanje:
Faka ipayipi lokubhoboza emgodini wokubhoboza ogcwele uketshezi lokugeza, shayela induku yokudlulisa eyisikwele evalekile emoyeni kanye ne-drill bit ukuze ujikeleze futhi usike idwala nomhlabathi ngokujikeleza kwetafula elijikelezayo, fafaza umoya ocindezelwe kusuka embotsheni yokufafaza ekugcineni kwepayipi lokubhoboza, bese wenza ingxube yegesi yamanzi esihlabathi sodaka elula kunamanzi nomhlabathi osikiwe nesihlabathi epayipini lokubhoboza. Ngenxa yesenzo esihlangene somehluko wokucindezela ngaphakathi nangaphandle kwepayipi lokubhoboza kanye nomfutho wokucindezela komoya, ingxube yegesi yamanzi esihlabathi sodaka kanye noketshezi lokugeza luyakhuphuka ndawonye bese lukhishwa emgodini wodaka noma ethangini lokugcina amanzi ngepayipi lokucindezela. Inhlabathi, isihlabathi, amatshe ayigugu kanye nodoti oqoshiwe uhlala emgodini wodaka, futhi uketshezi lokugeza lugeleza emgodini.
