The front of the machine is equipped with a stationary drill tip which is kept at 700–930 °C (1,300–1,700 °F). The molten rock is pushed around the edges as the vehicle is forced forward, and cools to a glass-like lining of the tunnel. Massive amounts of energy are required to heat the drill head, supplied via nuclear power or electricity.

[4] [5] During drilling operations, complex accidents such as gas invasion and overflow are prone to occur. [6] In addition, deep strata have poor diagenesis , weak pressure bearing capacity, so leakage is easy to happen, the risk of well control is high, and the treatment is difficult, which impact on deepwater wellbore integrity seriously.
