Abstract Based on parameters of GPS control points near wellbore between +370 m horizontal main haulage roadway and +520 m return air roadway in Hongyuan Mine, reasonable measuring circuit was designated by considering its breakthrough precision and traditional theodolite traverse coordinating with measurement of gyroscopic directed edge was selected according to reality. Internal work calculating and field operation on the basis of traverse survey was elaborated; meanwhile, its measuring error was predicted. As a result, adjustment of waistline in roadway was set forth through analysis of actual deviation.
