摘　　要：以淮北矿区芦岭煤矿贯通测量为例,通过在一定时间、地域差异井上定向边测定陀螺方位角,验证稳定状态下该陀螺全站仪的寻北精度稳定性;通过对井下一定距离定向边的定向,以井下搬运距离量化震动对仪器引起的误差,采集各陀螺定向边数据并评定寻北中误差;认为井下陀螺寻北稳定性随着搬运距离增大而大幅降低。建立井下陀螺定向中误差与搬运距离高相关性拟合方程,预测该陀螺全站仪连续搬运距离限制。Taking the holing through survey of Luling Coal Mine in Huaibei Mining Area as an example,based on the measurement of gyroscopic azimuth at directional edge in a certain time,regional differences wells,we testified the north-seeking stability of the gyro total station in a steady state.Through the orientation of the downhole directional edge in a certain distance,we quantify error caused by vibration of equipment by downhole carrying distance,and collect data of each gyro orientation edge and evaluate error in the north-seeking,we considered that gyro north-seeking stability is decreased with the increased of carrying distance.Based on the conclusions,we established high correlation fitting equation of the relationship about downhole gyro orientation error and carrying distance.According to this,the limitation of GT3-3 carrying distance could be concluded.
