Imikhiqizo yamashubhu yomkhakha kawoyela negesi isetshenziswe ngempumelelo kwezinye zezimo ezicindezela kakhulu zangaphansi kolwandle kanye ne-downhole futhi sinomlando omude oqinisekisiwe wokuhlinzeka ngemikhiqizo ehlangabezana nezidingo zekhwalithi eziqinile zomkhakha kawoyela negesi.
I-Meilong Tube inikezela ngamashubhu ahlanganisiwe ezinhlobonhlobo zezinsimbi ezingagqwali ezingagqwali, ama-nickel alloys.Sinolwazi olunzulu ekuhlinzekweni kwemikhiqizo kanye nokusungula izinto ezintsha kulo mkhakha, kusukela entuthukweni yezobuchwepheshe edingekayo ekuthuthukisweni kolwandle olungaphansi kolwandle ngo-1999 kuya ezinseleleni zamanzi ajulile zanamuhla.
