In coal mine and other underground engineering control survey,using the method of adding the azimuth edge of the gyroscope can significantly reduce the accumulation of direction errors and improve the control and measurement accuracy,especially in the underground engineering control and measurement with complex linear,large length and high measurement accuracy requirements,compared with only using the method of wire measurement.It is an ideal directional measurement tool that can not be replaced by other instruments and equipment.It is widely used in underground resource mining,water diversion tunnel,road(railway)tunnel,civil air defense and urban subway and other engineering construction,and has achieved high-precision measurement results.
