摘要
为了建立加测陀螺边严密平差模型,笔者在井下平面控制网平差中,加测陀螺定向边后,有边、角、陀螺方位角三类观测值,将陀螺方位角纳入平差模型,进行整体平差,并以某矿井井下观测导线为实例进行分析,结果表明,将陀螺方位角当作观测值整体平差,可以有效地改善测角误差传递引起的控制网整体摆动,提高井下导线点的点位精度,增加井下控制网的可靠性。
In the process of underground horizontal control network adjustment, there are three kinds of observations such as length of side, angle and peg-top azimuth after gyroscopic directed edge survey. Then the gyro azimuth is brought into the new adjustment mode and the overall adjustment is made. Taking the underground observation traverse of a mine as an ex- ample, the results show that it can effectively improve the whole swing of control network caused by the angular error trans- mission and improve the positional accuracy of the underground traverse point, then increase the reliability of underground control network.
