Mining intrinsic safety drilling rig drilling directional instrument, coal industry specific instrument

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, which uses a high-precision fiber optic gyroscope to determine the azimuth and tilt angle of the drilling rig, and accurately locate the drilling position for the drilling rig. 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 mesh, and anchor rods in traditional address compass measurement processes; Adopting angle compensation algorithm, it overcomes the problem of similar devices with inclination angle greater than 85 degrees; The defect of large azimuth error in the situation has enabled accurate measurement within the full range of inclination angles
