摘要
文中结合矿山深井多中段同时开拓的实际,应用全站式陀螺仪进行定向,采用一次投点,多中段同时联测,分次测定陀螺方位角的办法,解决了深井多中段定向中的技术难题。对定向结果进行精度分析,为井下首级控制提供了高精度的起始方位。
In this paper, combined with the practice of simultaneous mine development of multiple levels in deep wells , the total station gyroscope is used to orientate and separately measure the gyro azimuth of different levels in deep wells with launching the same one temporary point, which solve the technical crux of locating - direction of multiple levels in deep well. And the precision analysis on measuring results provides the high - grade initial direction of initial control under the well.
