Abstract: In order to cooperate with the application of the world’s first fast driving system in Daliuta Mine and solve the guiding problem in the process of roadway tunneling, and to increase the efficiency of continuous mining and decrease personnel, this paper applies fiber-optic gyroscope to the guide of roadheader. Miners can ascertain the attitude angles of roadheader on the basis of three Euler angles provided by the three-axis fiber-optic gyroscope. In conjunction with the traditional laser guide instrument, the quality of roadway tunneling promotes significantly. Result of application indicates that the accuracy of pitch angle and roll angle of fiber-optic gyroscope is 0.05° and the accuracy of yaw angle is 0.25°; the real-time deviation of roadway tunneling is less than 10 cm, thus this method can effectively prevent deviation of roadway tunneling and achieve significant improvement.
