Based on measurement and construction of curved roadway in coal mine, as well as analysis of the important role of curve roadway measurement on construction quality and production safety, measuring principles, calibration parameter calculation, field calibration method and large sample drawing method of the four measuring kinds of curve roadway which were chord method, tangent method, string tangent method and arbitrary chord length method were researched. At the same time, application scope, advantages and disadvantages of different methods were analyzed, which have important reference significance to the coal mine roadway curve measurement.
