Izinyathelo Zokusebenza:1.Uhlelo lokumba oluthwele kanzima luhlanganisa isando se-DTH, i-eccentric design reming kanye ne-pilot bit, insiza yokuqondisa kanye ne-casing.I-eccentric bit reming izungeza ibheke ngaphandle ukuze ibhoboze imbobo enkulu ukuze ivumele ikesi lensimbi lingene embobeni ngesikhathi esisodwa.Uthuli lwamadwala luphephethwa embobeni ngepayipi lebhokisi.2.Ngemva kokubhoboza ekujuleni okuthile, i-reamer izohoxiswa ngokuhlehlisa kancane isiqondiso sokuzungeza noma ngokudonsa ithuluzi, futhi yisikhathi lapho amathuluzi okubhola angakhishwa.3.Ukudonsa ikesi phezulu bese ugcwalisa ukhonkolo noma ezinye izinto ngaphansi komgodi.4.Ukusebenzisa i-drilling bit evamile kungabhoboza umgodi ngokuqhubekayo, kuyilapho i-DTH bit ingabhoboza ifinyelele ekujuleni okudingekayo.
