The hot-point drillis often tend to tilt in ice drilling， which results in deviation from the target ice and failure to complete the scheduled drilling mission. To this end， the causes for the inclination of hot-point drills are anaylized and categorized into uneven heating of the ice at the bottom of the thermal head， poor stability of the hot-point drill structure， higher speed of cable unwinding than penetration speed and oversized borehole diameter. The methods of preventing and correcting the inclination in hot-point drilling are summarized， including the thermal method， the gravity method， the buoyancy method， the push method， the centralizer method， the guide rod method and the borehole diameter reduction method， so as to lay a foundation for further research on preventing and correcting the inclination of hot-point drills.
