全站仪伪水准测量在矿井高程测量中的应用

Application of total station pseudo-leveling in mine height measurement

在矿山井下高程测量中,利用全站仪不量仪器高和棱镜高原理测高程,分析伪水准测量误差来源、精度等级。实践表明,全站仪伪水准测量能达到三、四等水准测量的精度要求。

At the mine height measurement,using principle of total station not measure the instrument high and prism high,analysised the source of error and accuracy grade of pseudo leveling.Through theoretical study and practical application,total station reach three or four degree measurement accuracy.
