Abstract

Summary

The paper presents selected results of GPR surveys carried out over former, shallowly located mine of sandstone. The aim of surveys was detection of fractured zones developed over the excavations which caused creation of subsidence areas and sinkhole. GPR surveys were conducted in 3D mode with profiles designed in two perpendicular directions. In interpretation influence of direction of the profiles to visualisation of spatial distribution of fractured zones was analysed. As it was shown in the paper ability of GPR detection of fractures in the rock mass depends on the direction of the profiles versus spatial distribution of fractures. Visibility od geological boundaries in radargrams for different orientations of the profiles is very similar.
