GAK-1陀螺经纬仪在铀矿井下定向中的应用

摘要

In order to strengthen the direction control of underground wire, reduce the cumulative effects of anglemeasuring error by long-distance penetrative wire and ensure transfixion precision, the Gyro-theodolite is used to orient the downhole traverse sides. The paper introduced Switzerland WILD GAK-1 Gyro-theodolite, and presented a case to orientate downhole traverse by reversal point method of Gyro-theodolite. This method improved the directional precision of roadway and analyzed some issues in the orientation.%为了加强矿山井下导线的方向控制,减少长距离贯通导线测角误差的累积影响,确保贯通精度,使用陀螺经纬仪对井下导线边进行定向.介绍了瑞士WILD GAK-1陀螺经纬仪,并通过实例对陀螺经纬仪采用逆转点法对矿井进行定向,从而提高巷道贯通精度,并对定向中遇到的一些问题进行了分析.
