浅谈巷道高程控制测量

Talking about Elevation Control Survey of Roadway

巷道控制测量包括平面控制测量和高程控制测量,巷道的标定和检查,以及绘制矿体和巷道在竖直面投影图和纵剖面图都需要进行高程控制测量。井下水准测量和三角高程测量是巷道高程测量的基本方法。本文主要介绍了井下水准测量、三角高程测量的观测方法,观测精度,以及相关注意事项。

The control survey of roadway includes plane control survey and elevation control survey,the calibration and inspection of roadway,as well as the drawing of ore body and roadway in vertical plane projection map and longitudinal profile map,all of which require elevation control survey.Underground leveling and triangular elevation measurement are the basic methods of roadway elevation measurement.This paper mainly introduces the observation methods of underground leveling and trigonometric leveling,the observation accuracy and the matters of concern.
