Emaphrojekthini okubhoboza phansi kwembobo asebenzisa umfutho ophezulu, ukuze kufezwe umgomo wokubhoboza okusebenza kahle nangokushesha, kuyadingeka ukukhetha ama-drill bit asezingeni eliphezulu futhi asebenza kahle, okungukuthi, ukukhetha ama-drill bit asebenzisa umgodi anezakhiwo ezahlukene ngokwezindlela ezahlukene zokubhoboza kanye nezinhlobo zamatshe. Uchungechunge lwezinto ezifana nesakhiwo sobuso be-drill bit, ukuma komsele wokukhipha i-powder, ukuma nosayizi wezinyo le-carbide, ubulukhuni bomzimba we-drill bit, njll. kuthinta ngqo izinga lokubhoboza edwaleni, ikhwalithi yokubhoboza, ukuqondile kwe-blasthole, impilo ye-drill bit kanye nokusebenza kahle komsebenzi. Ngakho-ke, ukukhetha i-drill bit efanelekile kubaluleke kakhulu kumaphrojekthi okubhoboza edwaleni.
Ngokuphathelene nama-drill bits anengcindezi ephezulu (ama-drill bits), kunezinhlobo ezine eziyinhloko zokwakheka kobuso obusekugcineni ezisetshenziswa njengamanje, okungukuthi: uhlobo lwe-end face convex, ubucaba bobuso obusekugcineni, uhlobo lwe-end face concave kanye nohlobo lwe-end face deep concave center. I-Carbide isebenzisa kakhulu amazinyo ebhola, amazinyo entwasahlobo noma amazinyo ebhola kanye namazinyo entwasahlobo ukuze kulungiswe amazinyo.
1. Uhlobo lobuso obuyindilinga: Uhlobo lobuso obuyindilinga olunomfutho ophezulu wokucindezela phansi komgodi (i-drill bit) lungagcina izinga eliphezulu lokubhoboza amatshe lapho kubhobozwa amatshe aqinile naphakathi nendawo, kodwa ukugoboza kuqondile, futhi akufaneleki kumaphrojekthi okubhoboza amatshe anezidingo eziphezulu zokuqina kwemigodi.
2. Uhlobo lobuso obuyisicaba: Uhlobo lobuso obuyisicaba olusebenzisa umfutho ophezulu (i-drill bit) luqinile futhi luhlala isikhathi eside, futhi lufanelekela ukubhoboza amatshe aqinile futhi aqinile kakhulu. Lufanelekela futhi ukubhoboza idwala eliqinile eliphakathi nendawo kanye nedwala elithambile elinezidingo eziphansi zokuqina kwembobo.
3. Uhlobo lobuso obugobile: Uhlobo lobuso obugobile olunomfutho ophezulu wokubhoboza phansi kwembobo (i-drill bit) lunengxenye egobile ekhonikhi ebusweni bokugcina, okwenza i-drill bit yakhe umphumela omncane we-nucleation ngesikhathi senqubo yokubhoboza idwala, igcina ukusebenza kwe-drill bit phakathi nendawo, futhi i-blasthole ebhoboziwe inokuqonda okuhle. Ngaphezu kwalokho, le bit yokubhoboza inomphumela ongcono wokususa uthuli kanye nesivinini sokubhoboza esisheshayo. Kuyi-drill bit ecindezelekile ephezulu esetshenziswa kakhulu emakethe njengamanje.
4. Uhlobo lwesikhungo esigobile esijulile sobuso: Uhlobo lwesikhungo esigobile esijulile sobuso obuphansi olunomfutho ophezulu womoya ophansi ophuma emgodini (i-drill bit) lunengxenye yesikhungo esigobile esijulile phakathi nendawo yobuso obuphezulu, esetshenziselwa i-nucleation enkambisweni yokubhoboza idwala. Ukubhoboza imigodi ejulile kungagcina ukuqondile kwembobo, kodwa amandla obuso bayo obuphezulu abunamandla kunezinye izinhlobo zezingcezu zokubhoboza, ngakho-ke kufanelekile kuphela ukubhoboza idwala elithambile kanye nedwala eliqinile eliphakathi nendawo.
