矿山测量是矿山开采过程中不可或缺的一项重要工作，井下控制导线作为矿山测量的重要组成部分，其作业方法和数据质量对矿井的生产，尤其是贯通工程等至关重要。其中，陀螺定向的应用是提高井下导线测量精度、保证工程质量常用的有效方法。 近年来，随着矿井向大型化、深部化的发展，陀螺定向技术在矿山贯通工程中的应用也越加频繁，加测陀螺边的数量也大大增加。因此，方向附合导线由单一导线发展到多结点的导线网（贯通前）直至多闭合环的闭合导线网（贯通后），其数据处理方法的研究和应用是保证矿山测量成果质量的重要一环。 论文在简要说明陀螺定向的原理和方法的基础上，对导线网中加测陀螺边的位置、加测陀螺边能否作为坚强边以及陀螺定向成果的可靠性等方面进行了详细的分析和探讨；尤其是针对大型的、多个贯通的工程，根据其贯通前和贯通后方向附合导线的不同情况，研究了方向附合导线网的平差模型和数据处理的方法，并利用VB编程语言设计了方向附合导线网的平差程序。

Mine surveying is an indispensable during mining is an important work, underground control wire as an important part of the mine survey, the operation method and data quality against mine production, especially crucial breakthrough engineering etc. Among them, the application of gyro directional is to improve the measurement precision, downhole wires used to ensure project quality of effective methods. In recent years, with the mine toward large-scale, deep development of directional technology in mines, gyro through the application makes frequent engineering, added measure the number of gyro edge skyrockets. Therefore, the direction connecting traverse more by a single wire to the wire nets (transfixion node before more than) until the closure closed loop wire nets (after), its through data processing methods of research and application is the guarantee Based on the brief instructions gyro directional principle and method of the foundation, on the edge of adding wire, the position of measuring gyroscope which adds gyro edge as strong edge and gyro can the reliability of directional achievements aspects to carry on the detailed analysis and discussion; Especially for large, multiple penetration the project, according to the direction of before and after piercing through the different connecting traverse, the direction connecting traverse nets flat to model and the data processing method, and USES the VB programming language design direction connecting traverse nets flat to poor program.
