      Research in various  geotechnical  engineering,  structural studies are  important component of surface,  it is
because a key component of deformation and failure are located, such as cracks, joints, bedding plane faults and
other discontinuities, and structure of surface  is usually represented by its geometric features, so the  geometric
structure of surface support levy collection techniques, methods and means of scientific, advanced, completeness,
accuracy is particularly important.
      Currently, the drill core measuring method is still widely used in underground or surface of the deep structure
determination of geometric method of holding signs. Although it is  simple, convenient,  practical, but for weak or
broken rock, drill core rate relatively low, accurately determine the structure of surface geometry is more difficult.
      Since undisturbed geological  drilling holes  in the wall to  maintain a complete  geological features,  so drilling
holes into the hole in the wall of detection, so that the project geologists complete and accurate access to geolog
ical data within the drilling equipment is digital panoramic borehole camera system.
      Borehole camera technology has been widely used in petroleum industry,  engineering  geology,  geotechnical
engineering, glaciers, mining engineering, and civil engineering. In most  practical applications,  the  technology of
drilling holes through the wall of the observation site to make up for exploration and investigation of other deficie
ncies.  It can be used to:
1) identification, estimation and measurement of geological features;
2) the differentiation of rock;
3) assess the porosity;
4) detectors, water flow, the entrance and accumulation of scale;
5) salvage operations and perforation secondary control;
6) advanced exploration, and so on.
      Geotechnical Engineering: Geotechnical Engineering in the drilling and oil  industry compared to light, but the
measurement accuracy and higher requirements. In the oil industry with little regard for the small cracks is import
ant in geotechnical engineering data; they may control the rock mass strength and stability. Borehole camera tech
nology in geotechnical  engineering a wide range of applications, such as geological exploration, quality inspection,
safety monitoring, project evaluation results so on.
      Some successful applications include a geological survey in  the  hole, engineer,  quality inspection of concrete
and so on.  In short, through a number of large projects' application and practice in recent years, digital panoramic
borehole camera system has been applied to the detection quality of concrete pouring, hidden hanger exploration,
reservoir leakage detection, landslide  investigation,  groundwater resource  exploration,  grouting  qualit y testing,
environmental  testing and  evaluation  in areas , civil, environmental and other industries has been widely used.
