I-TR460 Rotary Drilling Rig ngumatshini omkhulu weemfumba. Okwangoku, isixhobo sokugrumba iitoni ezinkulu sisetyenziswa ngokubanzi ngabathengi kwindawo yegeology. Ngaphezu koko, iimfumba ezinkulu nezinzulu zemingxunya ziyafuneka kulwandle olungaphesheya nangaphaya kwebhulorho yomlambo. Ke, ngokwezi zizathu zibini zingasentla, siphande kwaye saphuhlisa i-TR460 yokujikeleza ukubhola eneerandi ezinoncedo lokuzinza okuphezulu, inqwaba enkulu kunye nobunzulu kwaye kulula ukuthuthwa.
