Emaphrojekthini wokumba anengcindezi ephezulu, ukuze kufinyelelwe umgomo wokubhola ngendlela efanele futhi esheshayo, kubalulekile ukukhetha izingcezu zokubhola ezisezingeni eliphezulu nezisebenza kahle, okungukuthi, ukukhetha phansi -imigodi yokubhoboza enezakhiwo ezahlukene ngokwezindlela ezihlukene zokubhoboza kanye nezinhlobo zamadwala. Uchungechunge lwezici ezifana nesakhiwo sobuso be-drill bit end, umumo we-powder discharge groove, ukuma nezinyo le-carbide nosayizi, ukuqina komzimba we-drill bit, njll. kuthinta ngokuqondile izinga lokumba amadwala, ikhwalithi yokumba, ukuqondisa kwe-blasthole , impilo ye-drill bit nokusebenza kahle komsebenzi. Ngakho-ke, ukukhetha i-drill bit efanelekile kubaluleke kakhulu kumaphrojekthi okumba amatshe.
Maqondana nezingcezu zokubhola ezinengcindezi ephezulu (izingcezu zokubhoboza), kunezinhlobo ezine eziyinhloko zokwakheka kobuso obusetshenziswayo njengamanje, okungukuthi: uhlobo lobuso obuyi-convex, ukuphela kobuso obucaba, uhlobo lwe-concave yokuqeda kanye nobuso bokugcina bujulile. uhlobo lwesikhungo se-concave. I-Carbide isebenzisa amazinyo ebhola kakhulu, amazinyo entwasahlobo noma amazinyo ayibhola namazinyo entwasahlobo ukuze kulungiswe izinyo.
1. Uhlobo lobuso obuyi-convex ekupheleni: Uhlobo lobuso obuyi-convex ekupheleni kobuso obunomfutho ophezulu wokubhoboza imbobo (i-drill bit) lungagcina izinga eliphezulu lokumba amadwala lapho kubholwa amatshe abrasive aqinile aphakathi nendawo naqinile, kodwa ukuqondisa kokubhola akulungile, futhi ayifaneleki kumaphrojekthi okumba amatshe anezidingo eziphezulu zokuqondisa kwe-blasthole.
2. Uhlobo lobuso obuyisicaba: Ingxenye yobuso obuyisicaba yobuso obuyisicaba (i-drill bit) inamandla futhi ihlala isikhathi eside, futhi ifanele ukubhola amatshe aqinile futhi aqine ngokwedlulele. Ilungele futhi ukubhoboza idwala eliqinile eliphakathi nendawo kanye netshe elithambile elinezidingo eziphansi zokuqondisa kwe-blasthole.
3. Uhlobo lobuso bokuphela kwe-concave: Uhlobo lobuso bokuphela kwe-concave: uhlobo lobuso obunomfutho ophezulu we-down-the-hole (i-drill bit) lunengxenye ye-conical concave ebusweni bokuphela, okwenza i-drill bit yakhe umthelela omncane we-nucleation ngesikhathi sokumba idwala. inqubo, igcina ukusebenza kwe-drill bit's centering, futhi i-blasthole ebhoboziwe inokuqondisa okuhle. Ngaphezu kwalokho, le ntwana yokubhoboza inomphumela ongcono wokukhipha uthuli kanye nesivinini sokubhola esisheshayo. Kuyi-high-pressure down-the-hole bits esetshenziswa kakhulu emakethe.
4. Uhlobo lwesikhungo sobuso obujulile be-concave: Ubuso bokugcina uhlobo lwesikhungo se-concave ejulile uhlobo lomfutho womoya ophansi we-drill bit (i-drill bit) inendawo ejulile ye-concave emaphakathi maphakathi nobuso bokuphela, esetshenziselwa ukwenza i-nucleation inqubo yokumba amatshe. Ukubhoboza izimbobo ezijulile kungagcina ubuqotho be-blasthole, kodwa amandla ayo obuso bokuphela abuthakathaka kunezinye izinhlobo zezinsimbi zokubhoboza, ngakho ifaneleka kuphela ukubhola idwala elithambile kanye netshe eliqinile elimaphakathi.
