浅析伪倾角腰线标定法在井下斜坡道中的应用

摘要

The middle route of the theodolite method calibration waist line is the foundation of other calibration methods. This method is simple calibration work, but because of when the guy is not easy to accurately grasp the vertical direction of roadway, graphometer pull the usual accuracy is not high, the error often is bigger, the main roadway or precision angle is greater than 8o to demand higher general slant, with total station at the same time, in the midline in the area of the standard set by pseudo dip on the roadway for accurate the waist line can improve the precision.%经纬仪中线法标定腰线，是其他标定方法的基础。此方法标定工作简单，但由于拉线时不易准确掌握垂直巷道方向，半圆仪拉平时的精度不高，误差往往比较大，所以倾角大于8º的主要巷道或精度要求较高的一般倾斜巷道，用全站仪标设中线的同时，用伪倾角在巷道帮上准确标设腰线，可提高精度。
