摘　　要：为解决以往定向仪不抗振、岩样采取率不高等问题,利用时间与钻孔空间位置对应的关系,研制成功了KD型定向仪。详细介绍了该定向仪的基本构成、技术参数及现场应用情况。To solve the problems of non-vibration-resistance and low recovery of rock samples existing in orientation instrument which takes radial as reference, KD Orientation Instrument was developed out based on the relationship between time and space position of borehole. The basic structure, technical data and application in situ of the instrument were introduced in details.
