Deep Core Drilling: Electro-Mechanical or Thermal Drill?
In 1977/78 at Dome C, Antarctica, it was not possible to drill deeper than 905 m because of hole closure. The thermal drill was subsequently been modified to drill deeper in a fluid filled hole. Simultaneously, we have developed an electro-mechanical drill which employs a centrifuge device for separ...
