摘　　要：结合柠条塔超长巷道贯通测量工程项目进行贯通误差预计,提出改进导线观测方案,将磁悬浮陀螺定向测量应用到超长巷道贯通测量方案设计中,选择合理方案施测。巷道贯通后进行联测,巷道在主要方向上偏差0.072m,次要方向上偏差0.036m,巷道贯通测量方案设计合理,贯通精度优良。该超长巷道贯通测量工程的高精度贯通对今后的此类贯通测量工程有一定的借鉴作用。Modified conductor surveying method was put forward according transfixion error predicting of transfixion survey project of extra long roadway of Ningtiaota coal mine, directional surveying of magnetic suspending gyroscope was applied in transfixion surveying of extra long roadway, then reasonable scheme was selected.Combined determination was done after roadway transfixion, deviation in the main direction and the secondary direction of roadway was 0.072m and 0.036m, respectively.Roadway transfixion scheme was rea-sonable, transfixion precision was excellent.The highest precision of extra long roadway transfixion could reference for future transfixion surveying project.
