摘　　要：巷道贯通是井工矿的关键工序,贯通测量是巷道贯通的技术保障。本文梳理了地面控制网起始数据对贯通误差的计算公式,分析了起始方向误差对贯通相遇点的影响,对某些公式进行了简化、推证,得出了不同的结果。The tunnel through is a key working procedure in mine, which depends on valid means of measurement. In this paper, the calculation formula of the through error caused by the initial data of the ground control network is presented, and the effect of the initial direction error on the through meeting point is analyzed. Finally, different conclusions are derived.

关 键 词：巷道贯通 贯通误差分析
