摘　　要：文章以赞比亚谦比西东南矿体副井与南风井井深800m中段为例,叙述了在深井淋水大、风流大的情况下,通过一井联系测量将地面三维坐标系统传递至井下中段,并在合适位置测定陀螺定向边,并修正方位角,以提高井下起始边的平面坐标精度和导线边的方位角精度,从而实现大型巷道的对接贯通。In this paper,the three-dimensional coordinate system of the ground is transferred to the middle section of the underground by one-well contact measurement,and the directional edge of the gyroscope is measured in the proper position,taking the middle section of the sub-well of the south-east orebody in the southeast of Zambia and the deep 800m of the south-wind well.And the azimuth angle is corrected so as to improve the plane coordinate precision of the starting edge and the azimuth precision of the wire edge so as to realize the butt joint penetration of the large-scale roadway.
