Mining hole directional instrument, independent north finder, coal industry specific instrument

The autonomous north finder for mining borehole orientation is a new type of intelligent portable instrument for measuring the posture of drilling rigs. The instrument is equipped with a high-precision gyroscope and acceleration sensor, as well as automatic and manual north finding and switching functions. With one alignment, it can maintain high-precision repeated measurements, and the measurement process is not affected by geomagnetic and ferromagnetic substances, overcoming the problem of inaccurate measurement caused by magnetic substances such as drilling rigs, steel nets, and anchor rods in traditional address compass measurement.

n working principle

YHZ90/360(A）The intrinsically safe drilling rig drilling directional instrument for mining is a new type of intelligent portable instrument for measuring the posture of drilling rigs. The instrument is equipped with a high-precision gyroscope and acceleration sensor，both haveAutomatic North Search andManually search northBy changing the function and aligning once, high-precision repeated measurements can be maintained, and the measurement process is not affected by geomagnetic and ferromagnetic substances, overcoming the problem of inaccurate measurements caused by magnetic substances such as drilling rigs, steel mesh, and anchor rods in traditional address compass measurements; The angle compensation algorithm has been adopted to overcome the defect of large azimuth error in similar devices when the inclination angle is greater than 85 °, achieving accurate measurement of azimuth and inclination angles within the full inclination range and measuring full coverage.
