Zastosowanie otworowych profilowań geofizycznych do badania stanu górotworu w rejonie Szopienic

Comprehensive measurements and interpretation of well logs were done in several shallow, low diameter wells near Katowice Szopienice railway, in region of old mining excavation. Quantitative interpretation of well logs delivered detailed information about lithology, bulk density and porosity, which was a complementary data to results of surface geophysical measurements. Preceded by borehole camera investigations the following well logs were done in boreholes depending on their technical conditions: spectrometry of gamma ray, spectrometry of gamma-gamma log, standard gamma-gamma log, caliper and acoustic full wavetrain recording. Parts of rock formation of high porosity and low bulk density were showed as zones of low elastic parameters, in which risk of ground collapse increase.
