我队勘探的一个大型磁性矿，孔深在400～800米之间。多年来，一直未能解决方位角的测量问题，影响了工程进展和地质报告的提交。一九七三年以来，在上海地质仪器厂的协助下，先在43孔使用三台国产JDL－1型陀螺测斜仪进行了试测。在试测成功的基础上，又测量了遗留下来待测方位角的钻孔，到目前已测完钻孔11个，计30多个测次，取得了比较好的成果，现将使用情况介绍如下：
A large magnetic mine explored by our team with a hole depth of 400 to 800 meters. Over the years, the measurement of azimuth has not been resolved, affecting project progress and the submission of geological reports. Since 1973, with the help of the Shanghai Geological Instrument Factory, three domestic JDL-1 gyroscopes have been tested in 43 holes. On the basis of the successful test, the borehole left at the azimuth to be measured is measured. Up to now, 11 boreholes have been measured and more than 30 measurements have been taken and good results have been obtained. as follows:
