摘  要：本文以北煤公司冠山矿一、三井 -540m 水平岩巷巷道贯通为例，在比例尺为1：5000贯通平面图上进行方案设计，根据所使用的仪器，应用不同的方法，分别制定两套不同的设计方案。然后对两套方案进行误差预计和工程预算，将结果进行比较，选择既满足精度要求又经济、高效的测量方案作为最后的误差预计方案。最后求出已选方案陀螺定向边和贯通相遇点的最佳位置及贯通允许区间。

Abstract：This article takes the tunnel between Guanshan first mine and third mine of Northern Coal Group as an example. It carries on the plan design with the scale of 1: 5000. According to instrument it uses, it adopts different methods, and formulates two sets of different design proposals. Then it carries on the erroneous estimation and the project budget to two sets of plans, and carries on the comparison.It both satisfies the precision request and the economical, the highly effective survey plan as the final error estimation. Finally, it calculates the most optimum position of the gyrocompassing side and the transfixion engagement point and the permission sector of through survey.

Key words：through survey; error prediction; gyroscope orientation
