陀螺边定向法在井巷贯通测量中的应用及误差分析

Application and Error Analysis of Gyro Edge Orientation Method in Shaft and Roadway Penetration Measurement

为保证伯方煤矿三采区与五采区准备巷道的准确贯通,对三采区与五采区准备巷道实施加测陀螺定向边工作,对陀螺边定向测量的施工方法、施工标准及仪器校准等进行描述,并对误差评价的方法以及误差对测量结果的影响进行分析。经过每条定向陀螺边的互差计算,三采区G12-G14边与五采区G13″-G14边测回互差值均小于测量规程中不超过40″的规定。通过误差结果分析及时校正测量参数,为巷道顺利贯通提供依据。

In order to ensure the accurate connection of the preparation roadway between the third mining area and the fifth mining area in Bofang Coal Mine,the gyro oriented edge of the roadway is implemented,the construction method,construction standard and instrument calibration of the gyro edge directional survey are described.The influence of the error on the measurement result is analyzed,and the method of error evaluation is used to calculate the mutual difference of each directional gyro edge.The difference between the G12-G14 edge of the third mining area and the G13"-G14 edge of the fifth mining area is less than 40" in the survey rules.Through the analysis of the error results,the measurement parameters are corrected in time to provide a basis for the smooth passage of the roadway.
