摘　　要：通过对潜孔钻机凿岩过程中的地质条件、受力特征和钻孔偏斜机理进行研究,分析钻孔偏斜的主要原因,并提出钻孔偏斜的预防及处理对策。实践证明,采取合理的处理对策可以有效地控制潜孔钻机的钻孔偏斜问题。According to the research on the geological conditions, stress characteristics and mechanism of axial deviation in the process of rock-drilling by down-the-hole drill, the primary reasons of axial deviation in drilling holes and the preventive measures and countermeasures were proposed. The practice shows that with these methods, the axial deviation problem can be effectively controlled in process of drilling by down-the-hole drill.
