摘要
为了保证贯通精度,贯通前进行贯通误差预计;巷道掘进过程中采用两次独立观测(导线、陀螺),提高观测精度。结果表明:通过测量仪器、观测手段、数据处理方法的选取,可以确保一井内的精准贯通,此次14 km贯通工程精度达到水平重要方向贯通误差-0.182 m、高程贯通误差0.215 m。
Frist, in order to ensure an accurate, in the paper, the through forecast error was got. Secondly, in the heading process of the mine roadway, two independent survey(traverse and gyrostatic orientation survey) were used to improve the measurement accuracy. The results showed that the chose of survey instrument and survey technology and data processing method applied could ensure holing-through in a auxiliary shaft. The accuracy of the 14 km holing-through project reached an error of -0.182 m in the horizontal direction and an error of 0.125 m in an elevation direction.
