摘要
介绍了某矿回风立井与主井分别相向掘进三盘区辅助运输巷的测量工作过程。贯通工程贯通距离长、精度要求高、技术难度大,为了保证巷道准确贯通,在实际工作中采用了全站仪、陀螺仪等先进仪器和加测陀螺定向边、两次独立对中、增加测回数等技术措施,有效保证了测量精度。
In this paper, the author introduced measurement process of transportation roadway of San-pan area, through advancing of opposite direction of air return vertical shaft and main shaft. With features of long distance, high accuracy and extreme difficulty, the project was adopted technical measures of total station, gyroscope, directional annexed traverse after gyro, two independent centering and number of measurement, which effectively guaranteed measurement accuracy.
