摘　　要：为了提高矿井贯通测量的准确性和可靠性,对测量方案进行优化设计和误差预计分析,主要针对地面平面与高程控制测量、平面与高程联系测量以及井下导线测量方案及误差分析,计算了水平重要方向在X轴方向上误差预计和贯通相遇点在Y轴方向上误差预计,结果表明,贯通相遇点K在水平和高程上均未超出工程所要求的误差范围,选定方案和施工方法能够满足施工要求。In order to improve the accuracy and reliability of mine cut-through measurement,the measurement scheme was conducted by optimization design and error analysis,mainly aimed at the ground plane and elevation control survey,plane and vertical connection and underground traverse survey scheme and measurement error analysis,error prediction of the horizontal important direction in the X direction error and versed in meeting point in the Y direction error was expected,the results showed that the well versed in meeting point K on the level and elevation were not beyond the range of error of engineering required,the selected scheme could satisfy the construction requirements and construction methods.
