Currently, Vektore is the only consulting firm that provides this special kind of augmented service which allows advanced image interpretation of televiewer images collected from boreholes (Vektore's VBIA Method©).
Televiewer is a remarkable tool to acquire structural data from well-preserved historic and recently completed boreholes using its acoustic and optical probes. We use an industry-based software to interpret these images, but unfortunately industry-available software is not equipped with methods to extract linear and kinematic features from these images.
To overcome these weaknesses, we have developed a software solution to acquire and process linear and kinematic features from borehole images (vKore-Structural©). This implementation was proven to significantly improve the architecture of complex ore bodies which were later validated by underground mining (Thompson Nickel Belt). In addition, our unique approach is a novel way to record and evaluate break-out patterns, which are fundamental to the understanding of the stress field around mine sites.
The following table presents a summary of this plan, including goals to be achieved, and the value added to the client’s working toolbox and rational.
