I-Over Burden Drilling
Amathuluzi Okugaya Amandla Kakhulu
Amasistimu e-ODEX ezando ze-DTH eziklanyelwe ngokukhethekile ukubhola kanye nekesi ngesikhathi esisodwa ngomthwalo omningi.Lawa mathuluzi okumba aqinile adlula kalula ematsheni amakhulu ukuze adonse ayisindi lapho kufakwa khona amabhokisi ashibhile ngemva kwawo.Lawa mathuluzi okumba umthwalo osindayo kulula ukuwakhipha emgodini/ekujuleni futhi anikezwa amakhasimende ethu ngalezi zici ezilandelayo:
1. Kufakwe ekubhobolweni lapho ukwakheka kwamadwala kuwumthwalo omkhulu futhi kudinga ithubhu ye-casing ukuze kusekelwe.
2. eguquguqukayo ukuze uvule futhi uvale.
3. Uhla Lokufaka Isicelo: Lulungele ukumba imithombo yamanzi, imithombo ye-geothermal, kanye nama-miscopies amafushane ama-medium-type grouting imbobo yesakhiwo, iphrojekthi yedamu kanye namachweba.
4. Izimiso Zokuklama: Yenza i-casing ilandele kalula futhi okokusebenza nokusebenza kube lula
5. Izinzuzo Ezivelele: Isakhiwo esilula, ukusebenza okulula, ikhwalithi enokwethenjelwa, amathuluzi okubhola atholakalayo, impilo ende yesevisi.
6. Iphakethe langaphakathi elinamakhathoni, iphakethe langaphandle elinamacala okhuni
