Jiidista tilaabada waa birta loo qaabeeyey in loo isticmaalo qaabab jilicsan sida ciid, dhoobo, ama dhagax jilicsan.Si kastaba ha ahaatee, si fiican uguma shaqayn doonaan quruurux aan dhab ahayn ama samaynta dhagax adag.Isticmaalka waxaa ka mid ah qodista ceelasha biyaha, macdanta, geothermal. deegaanka iyo qodista sahaminta.Mar kasta oo ay suurtogal tahay, waa in loo isticmaalo qodida godadka tijaabada sababtoo ah waxay soo saaraan gooyn sida ugu fudud ee loo gooyo.
3 baalasha jaranjarooyinka jiiditaannada waa hal gabal oo dhismo bir ah oo bir ah oo leh talooyinka goynta carbide tungsten iyo dhinacyada cabbirka si loo hubiyo nolosha dheer.Waxay leedahay 3 baal iyo 3 godad oo biyo shuban ah.Marka la barbar dhigo 4 baal, 3 baalal tallaabo jiiditaannada waxay u muuqdaan inay si degdeg ah u qodaan oo dagaal badan yihiin, halka, ay yihiin kuwa ka gaaban waara oo ka yar.Xawaaraha miiska wareega ee talaabooyinka jiidista waa in uu ahaadaa inta u dhaxaysa 60 iyo 80 rpm oo leh miisaan yar oo yar (WOB).
3 baalasha jaranjarooyinka jiiditaannada waa qalab dhaqaale marka la qodayo qaababka juqraafiyeed ee jilicsan iyo moolka qoto dheer, waxaa ugu horrayn loogu talagalay qaababka jilicsan ee tomedium, sida dhoobada, Loam, Silt, Mostsoft-to-dhexdhexaad carrada oo leh xoogaa qoyaan, iwm. waxaa lagu talinayaa in laga qodo Macdanta, Sahaminta, Deegaanka, Ceelka Biyaha, Geo Exchange, iwm.
Xusuusin: Dhexroorka iyo dunta lagu muujiyay sida kor ku xusan waa cabbirka caadiga ah, cabbirro kale ayaa la heli karaa marka la codsado.
