Abstract Roadway excavation at both ends could improve the efficiency of excavation, but it put forward higher requirements for measurement. In order to form the working face system as soon as possible, Yushupo Mine adopted the construction method of excavation at both ends in No.5201 Face. Combined with the actual situation of the working face, the measurement scheme of roadway penetration was determined. In order to ensure the smooth penetration, measures including angle measurement accuracy control and midline control were proposed. The results showed that the horizontal error and elevation error of the penetration point were 88.6 mm and 47.1 mm respectively, which met the accuracy requirements. The working face was put into production in advance, which could provide reference for the excavation of long-distance roadway.
