Calculation and Engineering Application of Gyro Azimuth in Wells of Muti-adit's Single Shaft Orientation

矿井联系测量的重要任务之一就是矿井定向,即确定井下导线起算边的坐标及坐标方位角。本文通过在矿井井口下放一根钢丝用来获取地下导线起算点的平面坐标,利用陀螺经纬仪测出地下导线起算边的陀螺方位角,进而计算出坐标方位角,重点介绍了陀螺方位角测算过程,通过编写的陀螺方位角计算程序,可以实现多平硐矿井中多条陀螺方位角自动计算,并通过手工计算,说明了计算的准确性,实现了陀螺方位角数据计算的自动化。

One of the important tasks of mine contact measurement is mine orientation,that is,the determination of the coordinates of the starting point of the underground traverse and the coordinate azimuth of the initial side.In this paper,the plane coordinates of the starting point of the underground traverse is obtained by placing a steelwire in the well head of mine.Using the gyro theodolite to obtain the gyroscopic azimuth of the underground traverse,the coordinate azimuth of the initial side of the underground traverse is calculated. The gyroscopic azimuth calculation process is introduced in detail.With the calculation program of the gyroscopic azimuth,it can be realized the automatic calculation of multiple gyro azimuths in Multi-adit mine.And by manual calculation,the accuracy of the calculations illustrated,which realized the coordinate azimuth data calculation automation.
