Abstract: In order to improve the accuracy and reliability of the through survey for a mine roadway, a rational survey plan should be prepared and an effective surv ey method should be conducted.In combination with the project cases, the paper analyzed the surface ground control network, underground traverse survey, mine shaft orientation and gyro orientation edge survey influenced to the through accuracy of the mine roadway.The paper discussed the feasibility method to improve the measuri ng accuracy.With the prediction and analysis on the error of the through survey, the predicted ultra error between the two central lines in the through point was土304 m m and the predicted ultra error of the two grade lines was土184 mm, which could meet the Mine Survey Regulations and construction requirements and could verifty the rationality of the selected survey plan and method.
