I-Eccentric Overburden Drilling System
- Ibanga Lohlelo
Ilungele ukumba imithombo yamanzi, imithombo ye-geothermal, imigodi emifushane ye-mircopiles medium mini-type grouting yesakhiwo, iphrojekthi yedamu kanye nechweba.
- Izimiso Zokuklama
Yenza i-casing ilandele kalula futhi okokusebenza nokusebenza kube lula
- Izinzuzo Ezivelele
Isakhiwo esilula, ukusebenza okulula, ikhwalithi enokwethenjelwa, amathuluzi okubhola abuyiselekayo, impilo ende yesevisi.

- Ukusetshenziswa:
1. Ekubunjweni kwamadwala okungazinzile, i-casing iyadingeka ukulandela.
2. Imvamisa ekubhojweni komthombo wamanzi, ukuze kubhore imbobo enkulu.
3. Ukujula kokumba kungcono ngaphansi kwamamitha angama-40 ukulawula umgodi kahle.
4. Fanisa ku-6" isando kanye neshubhu lebhokisi lebhokisi elingu-194mm.
5. Umfutho womoya ungu-20 Bar kanye nevolumu yomoya engu-500 cfm.
6. Amathuluzi alandwa ukuze asetshenziswe emigodini elandelayo.
