Ihlanganiswe ukuze ifakwe ngokushesha futhi kulula, ingasetshenziswa ezingxenyeni ezincane zikakhonkolo wokwakha okuqinile.
Izitayela zekhanda zalo lonke uhlelo lokusebenza.
Amanani okuhlola abhalwe ngezansi atholwe kusetshenziswa ukhonkolo ongu-200-250kgs/cm (akukho ukuhlanganisa).
Umthwalo ophephile wokusebenza akufanele weqe u-25% wenani elishiwo.

Ukusetshenziswa:Okokuqala, sidinga ukusebenzisa i-drill kagesi ukuze sibhoboze ubukhulu obuthile bomgodi;
Okwesibili, ukubeka ipulaki yokwandisa emgodini;
Okokugcina, kusetshenziswa isikrudrayiva ukuze uqinise isikulufu kushubhu yokwandisa kuze kube indawo eshiwo
