YHZ90/360(G) Intrinsically Safe Borehole Orientation Instrument for Mining Drilling

The YHZ90-360(G) is a cutting-edge, intrinsically safe borehole orientation instrument specifically designed for mining drilling rigs. This advanced device integrates high-precision fiber optic gyroscope technology to provide accurate azimuth and inclination measurements, ensuring precise borehole positioning in challenging mining environments.

Applications:

  • Mining Rigs: Primarily used in coal mine drilling rigs for precise borehole orientation.
  • Laser Distance Measurement: Capable of measuring distances up to 100 meters with high accuracy.
  • High Magnetic Interference Areas: Ideal for locations with significant magnetic interference, such as in close proximity to steel structures or ferromagnetic materials.
 

Key Features:

  • High-Precision Measurement:

    • Equipped with a fiber optic gyroscope, the YHZ90-360(G) provides highly accurate azimuth and inclination measurements. Its range spans from -90° to +90° for inclination and 0° to 360° for azimuth with an accuracy of ±0.1°.
  • Laser Ranging Technology:

    • The instrument incorporates a laser ranging system, capable of measuring distances from 0.03 to 100 meters with ±1 mm accuracy. This provides reliable guidance for target alignment, even in environments prone to interference.
  • Automated North-Seeking:

    • The YHZ90-360(G) offers automatic north-seeking using the fiber optic gyroscope, allowing for quick setup and accurate orientation without manual calibration.
  • Magnetic Interference Resistance:

    • Unaffected by geomagnetic fields or ferromagnetic materials such as steel meshes or anchor rods, the instrument delivers reliable readings in environments with magnetic interference.
  • Wide Application Range:

    • Specifically designed for coal mine drilling rigs, this tool ensures accurate borehole orientation, even in difficult, high-interference environments, improving both efficiency and safety.

Working Principle:

  The YHZ90-360(G) is an intelligent, portable instrument that provides precise drilling rig posture measurement. Its advanced angle compensation algorithm eliminates azimuth errors at inclinations greater than 85°, ensuring accurate readings across the full range of inclinations (from -90° to 90°) and azimuths (from 0° to 360°). The instrument is equipped with a laser ranging system, which offers infrared guidance for target alignment, further enhancing precision.
