摘 要:义桥煤矿为满足大型贯通测量工作的需要,在井下导线控制网中适当位置加测了陀螺定向边,并对其进行了精度分析;从而有效地控制了井下导线网在方向上的误差积累,提高了导线网的精度,为井下贯通测量等井巷工程的顺利开展提供了技术依据。In order to meet the needs of large-scale through-measurement work,a gyro directional edge was added at an appropriate position in the underground wire control network in Yiqiao Coal Mine and the accuracy analysis was carried out.Error accumulation was effectively controlled in direction in the downhole traverse network and the accuracy of the traverse network was improved providing technical basis for smooth development of the underground breakthrough survey and other sinking and driving engineering.
