eng Abstract:
Structural-geological analysis, i.e. core fracturing assessment within the boxcut safety\nborehole was carried out on the basis of optical televiewer record evaluation. In general,\noptical televiewer (OPTV) probe provides a continuous, unwrapped, high-resolution digital\n360° image of the borehole-walls oriented towards the cardinal points. This technique\nprovides information about the strike, dip direction, dip angle and depth of foliation, bedding\nplanes and fractures, as well as the frequency, aperture and infillings of fractures. Information\nabout spatial characteristics of structural elements is one of its indisputable advantages and\nallows for subsequent statistical evaluations.\nThe structural mapping of boreholes of Boxcut safety boreholes were carried out within the\ncontract of IG CAS (Contract No. D/18/156/00) GEOMET, s.r.o. (as a customer, contract No.\n01/2018). The aim of the contractual research was the realisation and interpretation of the\nfractures by digital logging of boreholes walls.
