Senza imiphongolo engumongo, esetshenziswa njalo ekuhloleni amaminerali, lapho ukukhonkwana kungase kube amafidi angamakhulu ambalwa kuya ezinkulungwaneni ezimbalwa ubude.umgodi wokumba wedayimane wokuhlola kusebenzisa i-annular-impregrated diamond bits enamathiselwe ekugcineni kwezinti zokubhoboza ezingenalutho ukuze kusike umgogodla wetshe eliqinile.Amadayimane asetshenzisiwe alungile ukwenza amadayimane ebanga lezimboni ezincane.Asethwe ngaphakathi kwe-matrix yobunzima obuhlukahlukene, ukusuka ethusi ukuya ensimbi yezinga eliphezulu.Ubulukhuni be-matrix, usayizi wedayimane kanye nomthamo kungahlukahluka kuye ngedwala okufanele lisikwe.Izimbobo ngaphakathi kwebhithi zivumela amanzi ukuthi alethwe ebusweni bokusika.Lokhu kunikeza imisebenzi emithathu ebalulekile: ukuthambisa, ukupholisa, nokususwa kokusikwa kokubhoboza emgodini.Amasampula angumongo ayatholwa futhi ahlolwe izazi zokwakheka komhlaba ukuze kutholwe amaphesenti amaminerali kanye nezindawo zokuxhumana ze-stratigraphic.Futhi sikhiqiza izingcezu zokubhola eziwumgogodla wedayimane elifakwe i-premuim, izingcezu ezingezona amakhorali, amagobolondo aphindayo, izinduku zokumba, ama-overshots namanye amathuluzi okumba idayimane nezinye izisetshenziswa zophenyo lwesizinda, ukuhlola amaminerali kanye nezicelo zokumba imithombo yamanzi.
