摘要
本文根据武山铜矿井下 7″级基本导线控制测量工作中量取仪器高和反光镜高 ,通过对光电测边三角高程高差误差的分析 ,其测量精度可以满足井下I级水准测量精度的要求。
To measure instrument high and light-reflect mirror's high in Wushan's underground mine 7″ basic conductor control measurement, and through analysis on triangle height errors in photoelectric side measuring, could meet the accuracy requirements of Grade Ⅰfor underground operations.
