abstract = {Carbonate rocks are particularly susceptible to karstification, resulting in the formation of structures, such as enlarged fissures, caverns, and sinkholes. These structures pose direct risk to construction and human safety, especially in urbanised areas. In this study, we demonstrate the application of multimethod geophysical reconnaissance, combining electrical resistivity tomography (ERT), induced polarisation (ERT-IP), seismic refraction tomography (SRT), and multichannel analysis of surface waves (MASW), to identify the subsurface karst structures at two sites in the Silesian District, Poland. This methodology allowed the identification of the geological structure to a depth of up to 40 m, which exceeds the requirements for geotechnical reconnaissance. At site 1, Niedzieliska, a 30-m-wide and 20-m-deep structure, filled with younger sediments, was interpreted as a karst sinkhole. At site 2, Tucznawa, a 180-m-wide fault zone overlain with suffusion-susceptible sediments was identified. The multimethod geophysical approach presented here can be applied to locate and interpret subsurface karst forms in similar karst terrains worldwide. © 2022, Springer-Verlag GmbH Germany, part of Springer Nature.},

abstract = {Seismic and geodetic studies were carried out before, during, and after underground exploitation of a coal bed in Katowice - Kleofas Coal Mine, located in the Upper Silesia Coal Basin, Poland. Development of a subsidence trough was completed approximately 3 months after passage of a longwall exploitation in the coal seam. This was the time required for the subsidence trough to appear on the surface, which was confirmed by levelling measurements. Sharp changes in the elastic parameters were observed on each profile during subsidence trough development. This observation can result from changing tension and compression forces caused by increase and/or decrease of the elastic parameters of the rock mass. After completion of subsidence trough development, the rock mass appeared to return to its isotropic state and the observed changes ceased. Some minor fluctuations were noted, but they probably resulted from changes in groundwater levels, which might have affected the measured parameters. © 2018 Archives of Mining Sciences.},

abstract = {The paper presents results of measurements of seismic wave velocity anisotropy. The results obtained were compared with direct structural measurements. The investigations were carried out in the Triassic carbonate deposits in the NE margin of the Upper Silesian Coal Basin (the USCB). Three areas have been chosen: Strzyzowice, Ujejsce, Strzemieszyce. The velocity of wave propagation was measured in profiles which were radially set, so it was possible to determine the orientation of fracture in the rock mass. The results were estimated on the basis of 2-rank and 4-rank tensors. In the case of strong anisotropy of seismic waves and small numbers of joint sets, there was a good correlation of seismic and structural measurements.},
