Structural-geological analysis, i.e. core fracturing assessment within the boxcut safety
borehole was carried out on the basis of optical televiewer record evaluation. In general,
optical televiewer (OPTV) probe provides a continuous, unwrapped, high-resolution digital
360° image of the borehole-walls oriented towards the cardinal points. This technique
provides information about the strike, dip direction, dip angle and depth of foliation, bedding
planes and fractures, as well as the frequency, aperture and infillings of fractures. Information
about spatial characteristics of structural elements is one of its indisputable advantages and
allows for subsequent statistical evaluations.
The structural mapping of boreholes of Boxcut safety boreholes were carried out within the
contract of IG CAS (Contract No. D/18/156/00) GEOMET, s.r.o. (as a customer, contract No.
01/2018). The aim of the contractual research was the realisation and interpretation of the
fractures by digital logging of boreholes walls.
