Borehole Wall Televiewer Borehole Acoustic Optical Televiewer Borehole Logging Fractured Observations Borehole Wall Imaging Tool
Application
1) For high definition imaging and recording of full borehole wall, snapshot of key positions, and measurement of borehole trajectory;
2) Measuring space trajectory and actual depth of boreholes;
3) Observing occurrence and development of fault crevice;
4) Observing water outlet position in water-bearing fault, channeling & karst cave, and water-bearing stratum;
5) Observation and quantitative analysis of strike, thickness, trend, dip angle of coal seam and ore body, and bed separation degree of dirt band between seams and roof strata.
6) Measuring the thickness, width, strike, trend, and dip angle of stratum or various structures on image plane;
7) Distinguishing various geologic structures like ore body, rock mass, coal seam, dirt band, and soil layer, etc.
8) Especially appropriate for detection of geologic structure of coal mine roof, coal seam occurrence, fault structure in front of working face, and diversion fissure zone in overlying strata;
9) Appropriate for detection of boreholes of various shapes and functions such as horizontal hole, vertical hole and inclined hole; bolt and cable hole, gas drainage hole, oil and water drainage hole, and geological prospecting hole, etc;
