Kwiiprojekthi zokumba eziphantsi komngxuma ezinoxinzelelo oluphezulu, ukuze kufezekiswe injongo yokumba okusebenzayo nokukhawulezileyo, kuyimfuneko ukukhetha iibhithi zokumba eziphantsi komngxuma ezikumgangatho ophezulu nezisebenzayo, oko kukuthi, ukukhetha iibhithi zokumba eziphantsi komngxuma ezinezakhiwo ezahlukeneyo ngokweendlela ezahlukeneyo zokumba kunye neentlobo zamatye. Uthotho lwezinto ezifana nesakhiwo sobuso be-drill bit end, imilo yomngxuma wokukhupha umgubo, imilo kunye nobukhulu bezinyo le-carbide, ubunzima bomzimba we-drill bit, njl.njl. zichaphazela ngokuthe ngqo izinga lokumba ilitye, umgangatho wokumba, ukuthe tye kwe-blasthole, ubomi be-drill bit kunye nokusebenza kakuhle. Ke ngoko, ukukhetha i-drill bit efanelekileyo kubaluleke kakhulu kwiiprojekthi zokumba ilitye.
Ngokuphathelele iibhithi zokubhola eziphantsi koxinzelelo oluphezulu (iibhithi zokubhola), kukho iindlela ezine eziphambili zoyilo lobuso obuphezulu ezisetyenziswayo ngoku, ezizezi: uhlobo lwesiphelo sobuso obungqukuva, ubucaba bobuso obuphezulu, uhlobo lwesiphelo sobuso obungqukuva kunye nohlobo lwesiphelo sobuso obungqukuva obunzulu. I-Carbide isebenzisa kakhulu amazinyo ebhola, amazinyo entwasahlobo okanye amazinyo ebhola kunye namazinyo entwasahlobo ukulungelelanisa amazinyo.
1. Uhlobo lobuso besiphelo esingqukuva: I-drill bit yohlobo lwesiphelo esingqukuva enoxinzelelo oluphezulu (i-drill bit) inokugcina izinga eliphezulu lokugrumba ilitye xa kugrumba amatye aqinileyo naphakathi, kodwa ukugrumba kuthe tye, kwaye akufanelekanga kwiiprojekthi zokugrumba amatye ezineemfuno eziphezulu zokugrumba imingxuma.
2. Uhlobo lobuso obuthe tyaba: Uhlobo lobuso obuthe tyaba olusebenzisa uxinzelelo oluphezulu oluphantsi komngxuma (i-drill bit) luqinile kwaye luhlala ixesha elide, kwaye lufanelekile ukugrumba amatye aqinileyo nanzima kakhulu. Lukwafanelekile ukugrumba amatye aqinileyo naphakathi kunye namatye athambileyo aneemfuno eziphantsi zokuqina kwemingxunya.
3. Uhlobo lobuso besiphelo esigobileyo: Uhlobo lobuso besiphelo esigobileyo olunoxinzelelo oluphezulu oluphantsi komngxuma (i-drill bit) lunenxalenye egobileyo ekhonkxiweyo kubuso besiphelo, nto leyo eyenza ukuba i-drill bit ibe nefuthe elincinci le-nucleation ngexesha lenkqubo yokumba ilitye, igcina ukusebenza kwe-drill bit ephakathi, kwaye i-blasthole ebotshiweyo ilungile. Ukongeza, le bit yokumba inefuthe elingcono lokususa uthuli kunye nesantya sokumba esikhawulezayo. Yi-drill bit yokumba engaphantsi komngxuma enoxinzelelo oluphezulu esetyenziswa kakhulu ngoku kwimarike.
4. Uhlobo lweziko eligobileyo elinzulu lobuso: Uhlobo lweziko eligobileyo elinzulu lobuso obuphantsi komoya ophezulu, olunomoya ophezulu, olusebenzisa i-drill bit (i-drill bit) luneziko eligobileyo elinzulu embindini wobuso bokugqibela, elisetyenziselwa i-nucleation kwinkqubo yokubhola amatye. Ukubhola imingxunya enzulu kunokugcina ukuthe tye komngxuma, kodwa amandla obuso bawo obuphezulu abuthathaka kunezinye iintlobo zee-drill bits, ngoko ke lufanelekile kuphela ekubhobheni amatye athambileyo kunye namatye aqinileyo aphakathi.
