Senza imiphanda engundoqo, esetyenziswa rhoqo kuphononongo lweminerali, apho ikhoringi inokuba ngamakhulu aliqela ukuya kumawaka aliqela eenyawo ubude.Ukomba wedayimani ophononongayo kusebenzisa intwana yedayimane emiliselweyo emiliselwe kwincam yeentonga zokubhola ukusika umbindi we-cylindrical welitye eliqinileyo.Iidayimani ezisetyenzisiweyo zilungile kwi-microfine yedayimani yodidi lweshishini.Zibekwe ngaphakathi kwe-matrix yobunzima obuhlukeneyo, ukusuka kubhedu ukuya kwintsimbi ephezulu.Ubulukhuni be-matrix, ubungakanani bedayimane kunye nedosi inokwahluka ngokwelitye ekufuneka lisikwe.Imingxuma ngaphakathi kwebit ivumela amanzi ukuba ahanjiswe ebusweni bokusika.Oku kubonelela ngemisebenzi emithathu ebalulekileyo: ukuthambisa, ukupholisa, kunye nokususwa kwe-drill cuttings emngxunyeni.Iisampulu ezingundoqo zifunyanwa kwaye zivavanywe ziingcali zejoloji kwiipesenti zezimbiwa kunye neendawo zoqhagamshelwano zestratigraphic.Kwakhona sivelisa amasuntswana okomba edayimani amiliselweyo, iingceba ezingakhongozeli, amaqokobhe okugraya, iintonga zokomba, ii-overshots kunye nezinye izixhobo zokomba idayimani kunye nezixhobo zophando lwesiza, uphononongo lwezimbiwa kunye nezicelo zokomba wamanzi.
