Kukho iintlobo ezininzi zeizixhobo zokubhola ezijikelezayoIzixhobo ezahlukeneyo zokubhola ezijikelezayo kufuneka zikhethwe kwiindawo ezahlukeneyo zokwakha kunye neendidi ezahlukeneyo.
a. Isixhobo sokuloba i-slag kunye nebhakethi yesanti kufuneka zisetyenziswe ekulobeni i-slag;
b. I-barrel bit mayisetyenziswe kwi-stratum yelitye enamandla aphantsi;
c. Xa kusetyenziswa i-conical spiral bit, kufuneka kusetyenziswe i-coring bit ekhethekileyo kwi-core sampling;
d. Ibhakethi yokubhola ejikelezayo mayisetyenziswe kumaleko womhlaba;
e. Xa kukho inqwaba yentsimbi, i-belled bit mayisetyenziswe kwinxalenye yentsimbi;
f. Xa i-stratum yelitye enamandla aphezulu iwela kwaye ibhakethi yokubhola ejikelezayo ingakwazi ukuqhubeka nokubhola, kufuneka kusetyenziswe i-screw bit yekhowuni;
Ukukhethwa kwezinto zokumba ezijikelezayo kuya kuchaphazela ukusebenza kakuhle kolwakhiwo. Ukuba izixhobo zokumba zikhethwe ngokuchanekileyo, ukusebenza kakuhle kolwakhiwo lwesixhobo sokumba esijikelezayo kuya kuphucuka kakhulu.
