Emergency rescue technology in mines and underground works has developed rapidly in recent years， and it has been found that the mode of the small diameter life support hole combined with large diameter rescue wells is an effective way to carry out mine disaster rescue. With the drilling technology for life support holes in mine disasters as the main subject， this paper analyzes the typical structural design of the small diameter life support hole and casing selection， describes mud direct circulation drilling， air DTH hammer reverse circulation drilling， and presents drilling difficulties in the case of the rescue of Qixia Hushan Gold Mine. In view of the deviation of the No. 3 life support hole in the rescue， based on the trajectory design theory， the ultra-short-distance spiral correction technology was innovatively proposed. The method has achieved good results， and provides valuable experience for subsequent life support hole construction.
