利用陀螺经纬仪提高煤矿井下巷道贯通精度的分析

Analysis of using Gyro Theodolite to improve the penetration precision of coal mine underground roadway

陀螺经纬仪是进行深部矿山精密定向、大型隧道工程精准控制、长距离巷道贯通测量等主要测量工作必备的仪器设备。文中通过对井下巷道进行贯通误差预计后,科学合理确定陀螺加强边的定向数量和位置,以保障煤矿井下长距离巷道的最终高精度贯通。

The gyro theodolite was a necessary instrument for major measurement work such as precise orientation of deep mines,precise control of large tunnel projects,and long-distance tunnel penetration measurement.After predicting the penetration error of the underground tunnel,the orientation number and position of the gyro reinforcement edge were scientifically and reasonably determined to ensure the final high-precision penetration of the long-distance tunnel in the coal mine.
