abstract = {Long-term underground exploitation of Zn-Pb ores has led to drainage of the area and formation of a huge dumping ground in the form of a pile. In its vicinity, processes of acid drainage have developed as a result of contamination of soils and groundwater. Geochemical transformations of mineral contents of waste can significantly affect physical and chemical properties of the soils and the bedrock. At the prospect of termination of the mining activity in the near future, determining the routes of the pollution migration, ability to monitor acid drainage processes and assessment of the risk of heavy metal pollution are really crucial. The paper presents a proposal for solving this problem by means of geophysical methods: Electrical Resistivity Tomography (ERT), Time Domain-Induced Polarisation (TDIP), Frequency Domain Electromagnetics (FDEM) and shallow-depth magnetometric surveys combined with geochemical investigations. The obtained results of geophysical surveys have been confirmed by geochemical investigations. The applied ERT and TDIP methods make it possible to identify the spread of the zones of pollution around the tailing pile, but their effectiveness depends on humidity of the ground. Soil magnetometry and shallow-depth induction profiling are a good tool to identify the medium contaminated with minerals redeposited by aeolian processes and allow to determine the range of the dust spread from the pile. It has been shown that the range of impact of the geochemical changes around the tailing pile is high and depends not only on directions and dynamics of water flow from the pile but also on aeolian transport. © 2020, The Author(s).},

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 results of geophysical studies conducted with selected electrical and electromagnetic methods in the Kondratowa Valley in the Tatra Mountains (the Carpathian Mountains; Poland) are presented in the article. The surveys were performed with the following methods: electrical resistivity tomography (ERT), georadar (GPR) and conductivity meter (CM). The objective of the noninvasive geophysical measurements was to determine the thickness of the Quaternary postglacial sediments that fill the bottom of the valley and to designate the accumulation of boulders deposited on Quaternary sediments. The results of ERT surveys conducted along the axis of the valley allowed to determine the changeability of the thickness of the postglacial sediments and allowed to designate a few areas of occurrence of boulders. The ERT, GPR and CM surveys conducted across the valley allowed to designate with high accuracy the thickness of the accumulation of boulders sliding down the valley bottom from the couloirs surrounding the valley. © 2017 Institute of Geophysics, Polish Academy of Sciences & Polish Academy of Sciences.},

abstract = {The depletion of Zn-Pb ores in developed mining areas and the increase in metal prices have resulted in the need to search for new deposits which have not been exploited yet. A project of drilling new exploratory boreholes should be preceded by an interpretation of archival geological data. To obtain the most valuable information on the geological structure leading to its plausible interpretation, it seems to be purposeful and advisable to apply some geophysical methods that are reasonably cheap in comparison with others. The method of electrical resistivity tomography, which in this research uses two of many measurement protocols such as Schlumberger array and dipole-dipole array, is particularly useful. Computer interpretation of geophysical results allows a high resolution 2D and 3D geoelectrical model of rock mass to be created. The study was carried out using the multi-electrode Lund Imaging System manufactured by ABEM, Sweden. In order to evaluate the practical application of this method, Zawiercie Zn-Pb ore deposits were chosen as the area used in previous scientific research. Taking into account mineralization in its economic aspect, the deposits occur at relatively shallow depths of 50-120 m. In the investigated region, the Triassic carbonate formation overlays the Devonian rocks. The Keuper low-resistance clay, occurring on the surface, provides a very good electrical contact between an electrode and the soil. This is why there are favourable measurement conditions in this area. The boundaries between the Keuper, Devonian and Triassic formations are clearly noticeable in the resistivity cross-sections obtained. On the basis of the ERT results, it ispossible to locate faulting zones as well as karst systems. One of the profiles clearly shows the occurrence of a low-resistance anomaly correlated with Zn-Pb mineralization, which was confirmed by borehole surveys. However, this early stage of the research with the use of the ERT method cannot unequivocally identify the ore body, particularly as it was conditioned by the limited depth of prospecting.},

abstract = {Depletion of exploited mineral ore resources and their constant price increase have contributed to active interest in recognition and exploitation of new workable deposits. Exploration work which has been carried out in the vicinity of nonexploited ore areas such as Klucze, Zawiercie and Laski results in confirmation of Zn-Pb commercial deposits. In this region Zn-Pb ores occur in the Devonian and Triassic carbonate formation at a depth of 70 - 80 metres under the surface. Geological recognition is based on the analysis of data taken from bore-holes. To determine the mode of the ores occurrence and service conditions, it is necessity to work out a spatial image of overburden structure. For this reason resistivity measurements with highly distributed LUND Imaging System were introduced in the area of Zawiercie I. The studies were carried out according to three measuring protocols: Schlumberger, Wenner and dipole-dipole. The measurements were performed along three parallel six-hundred-metre profiles. The resistivity cross sections were elaborated using Res2D software. The results of the geophysical research were correlated with the data taken from bore-holes in order to testing the efficiency of applied geoelectrical methods. The study showed a significant diversification of geoelectric characteristics of the rockmass and thus it allowed to recognise accurately the overburden structure of the deposit and to locate precisely zones of faulting. In future, the applied geoelectrical methods are certainly to be used for localization ore bodies at a considarable depth range.},

abstract = {Constructing highways in underground exploitation regions is difficult because mining and phenomena related to it, like induced seismicity, are always connected with surface subsidence. Therefore, it is interesting to check if there is any relation between the mining tremor occurrence and surface subsidence in case of coal longwall extraction. For such an analysis the area of the Katowice- Kleofas Colliery has been chosen. An excavation has been done below the A-4 motorway under construction. The subsidence had been measured periodically since 1999. All tremors with energy ≥ 1.102 J have been selected from the catalogue of the coal mine. Up to April, 2001, the surface came down more than 1 m and more than 6500 tremors have appeared.},

Velocity and attenuation coefficient of head waves have been analyzed and correlated with surface subsidence. Observed variability seems to be logical and consistent with the process of subsidence through development. On the basis of obtained results it is concluded that the process of rock mass deformations due to underground mining generates measurable changes of propagation velocity and coefficient of attenuation of seismic head waves.},
