Mining Gamma Borehole Camera Logging Instrument

The YHCJ90/360 Mining Borehole Tester is an integrated multi-parameter detection device. It measures natural gamma radiation intensity, borehole temperature, spatial trajectory, high-definition panoramic imaging, and dynamic video recording. By integrating multiple parameters, it accurately determines surrounding rock types and integrity, assesses rock support areas, locates water bursts and gas emissions, and assists in designing roof and floor support solution as well as water and gas prevention measures.

  • Soil NailingHoles: Classify roof and floor surrounding rocks, evaluate integrity, and guide rock support design.
  • Gas Drainage Holes:Locate gas emission points based on rock fragmentation, crack development, stratification, and temperature for auxiliary evaluation of gas drainage effectiveness.
  • Drainage Holes:Evaluate the effectiveness of water extraction based on rock fragmentation, crack development, stratification, and discharge point positions.
  • Geological Exploration Holes:Classify strata, observe water-bearing faults, karst caves, and fractures; accurately measure structural thickness, width, strike, dip, and inclination; and automatically generate geological columnar diagrams.
  • Borehole Spatial Trajectory:Measure deviations from design trajectories and evaluate borehole quality and effectiveness.
  • Specialized in:Coal mine roof geological structures, coal seam deposits, front fault structures, and overburden rock water-conducting fractures.
  • Adaptable Borehole Types:Horizontal, vertical, and inclined holes, including anchor rod and cable holes, gas drainage holes, drainage holes, and geological exploration holes.

Multi-functionality: Real-time panoramic imaging, video recording, image snapshots, trajectory measurement, gamma radiation, and temperature measurement.

High Integration: Fully integrated system for control, image/signal acquisition, display, and storage.

Intelligence: High-speed ARM quad-core processor, real-time panoramic image generation, depth and angle correction, and video replay capabilities.

Reliability: Sealed system with excellent waterproof and dustproof properties.

High Definition: 700TVLines color low-light camera, adjustable light intensity, and 360° panoramic imaging.

Portability: Compact design, lightweight, and easy to operate.
