提高罗盘仪导线测量精度的探讨

Discussion on Improving Measurement Accuracy of Compass Traverse

罗盘仪具有轻便灵活、操作简便、观测速度快、适合在狭窄地段测量等优点,是井下天井、天井穿脉工程和采场测量等的主要测量仪器。但是由于井下大量采用以铁代木,产生磁性干扰,使观测条件很难达到上述要求。运用测量误差理论,对罗盘导线进行误差分析,提出了提高罗盘导线精度的若干措施,以期使罗盘导线在黄金矿山发挥更好的作用。

The compass has a lot of merits, for example, light and flexible, the operation to be simple facilely, the observation speed quick and suits in narrow land sector survey and so on. It is the main instrument in the process of surveying the courtyard and underground stope measurement. Because it uses a large number of irons instead of wood in the underground, has the magnetic disturbance, causes the observation condition very inaccessibility the above request. Using the measuring error theory, we has carried on the error analysis to the compass wire, proposed many certain measures of increasing the compass wire precision, in order to be able to extend service life of the compass in the gold mine.
