介绍了凡口铅锌矿新副井延深贯通工程实践中的测量方法及其精度分析。采用经多次检测无误、标志稳固的起始点坐标及标高作为起始数据 ,进行坐标、方位、高程传递 ,保证了测量精度。同时采用陀螺定向系统有效地抑制了导线横向误差积累。为新副井延深精确贯通提供了技术保障
This paper introduces the measuring method and its accuracy analysis of the new auxiliary shaft of Fankou lead-zinc mine through deep penetration engineering practice. After many times of detection, the stable starting point coordinate and elevation as the starting data, coordinate, azimuth and elevation are transmitted to ensure the measurement accuracy. At the same time, the use of gyro-oriented system effectively restrain the accumulation of the lateral error of the wire. The new subsidiary well to provide accurate technical support
