Article
Fractured speleothems, important earthquake environmental effects used in paleoseismological studies worldwide, are particularly effective for dating. Here, we discuss physical phenomena that can damage caves. We supplement the discussion with information (frequency characteristics and ground-motion parameters) from areas of mine openings threatene...
Article
This paper presents the results of new research on ground-motion relations from three areas in the Upper Silesia Coal Basin (USCB) in Poland and compares them with of ground-motion relations. These three mining areas of the USCB were investigated in order to better predict ground motion caused by seismic events. The study focused on variations in r...

The research concerned horizontal-to-vertical (H/V) spectral ratios calculation for rotational and translational signals that two seismic stations registered. At first, called Imielin (IMI), the sensors were deployed in the technical venue. The second place, called Ziemowit (ZIE), assumed the situation of the sensors mounting on the ground floor of...
Article
The effectiveness evaluation of long-hole destress blasting in an underground hard coal mine was made via the seismic effect method and the seismic moment tensor inversion. The seismic effect method is based on the difference between seismic and explosive energies , indicating that additional processes appeared to change the stress state in the roc...

The rotational and translational signals were registered at the Planetarium ("PLA") station due to mining exploration, localized in the central part of the Upper Silesian Coal Basin. Visual inspection of the data peak values showed that the scaling relation between peak rotational velocity PRV and peak ground acceleration PGA could be expressed by...
Article
Multiphase cave conduit offset and related speleothem damage in the Demänová Cave System (DCS; the Low Tatra Mts, Central Western Carpathians) were dated with U-series methods, revealing five events: (1) 570 (442)–417 ka, (2) 306–291 ka, (3) 184–130 ka, (4) ~19 ka, and (5) 2.56–2.3 ka. To decipher the cause of the damage, we combined geochronologic...

We present the study of a subglacial drainage system that developed in the base of the Scandinavian Ice Sheet at the border of the Silesian Lowland and Silesian Upland (southern Poland) during the Drenthian Glaciation as a result of large outburst flood events. This drainage system was characterised by a spatially complex structure, i.e. it was com...

Multiphase speleothem damage and passage collapse in Niedźwiedzia Cave (NE Bohemian Massif, Poland) were dated with U‐series methods, revealing five events: (1) 320‐306 ka, (2) 253‐236 ka, (3) 162‐158 ka, (4) 132‐135 ka, and (5) >21 ka. Events 1, 3 and 4 are robustly constrained, and events 2 and 5 are less certain. Although we cannot unambiguously...
Article
Full-text available
Underground coal seam mining has been carried out in the Upper Silesian Coal Basin, Poland, for many years and with a simultaneous increase in exploitation depth. Frequently, coal seams are not fully extracted due to numerous reasons which lead to their edges and remnants remaining in the rock mass. Even in the case of the full extraction of a coal...

Full-text available
The underground mining of coal seams in the Upper Silesian Coal Basin is carried out at great depths and mostly in the presence of remnants or edges of other surrounding coal seams, i.e. under the condition of high stress level in the rock mass. Therefore, this mining is accompanied by rockburst hazard and suitable preventive action is required. Lo...

Clastic deposits in Kalacka Cave in the Tatra Mts. Show soft-sediment deformation structures (SSDS) rare for a cave environments. The poorly sorted allochthonous sediments were deposited within a cave sump under a fluvial regime, likely due to glacially initiated back-flooding during the Last Glacial. The structures include small-scale faults (norm...
Article
The city of Sławków has witnessed the metallurgical industry from the Middle Ages to modern times. The lead smelting causes usually contamination by a slag waste dump, threatening the environment of the vicinity of the cities. Similar industry existed in many places around the world but, so far, no geophysical work has ever been reported to deal wi...

Deep longwall mining of coal seams is made in the Upper Silesian Coal Basin (USCB) under complicated and mostly unfavourable geological and mining conditions. Usually, it is correlated with rockburst hazard mostly at a high level. One of the geological factors affecting the state of rockburst hazard is the presence of competent rocks in the roof of...

We would like to test the concept that induced seismicity prior to relatively large mining tremor (ML > 2.5, E > 10^6J) can be inferred from the cumulative Benioff strain release (BSR) as power law time-to-failure before the strong event. This study presents the application of accelerating BSR prior to a large earthquake, widely used in natural sei...
Article
The Upper Silesia region of Poland is known for its concentration of heavy industry, including mining and smelting. Slag dumps scattered across the region are the sources of pollutants such as Zn, Mn, As, Cd and Pb. At the slag dump in Ruda Śląska, it is possible to distinguish three types of slag: (i) slag associated with the muffle/lining materia...
Article
The direct dating of pre- and postfaulting dislocated calcite speleothems afforded new insight into slope failure in the Tatra Mountains in southern Poland. A multi-approach study of the karstic Kalacka Cave (non-crevasse type) enabled us to infer the slope deformation structure, which had been poorly preserved in ground surface topography, using c...

The aim of the study was to find the best model of ground-motion prediction equation (GMPE) forecasting peak ground acceleration (PGA) caused by induced seismicity. The maximum values of PGA on the surface are a major seismic threat for the infrastructure, especially in the highly urbanized areas, such is the Upper Silesian Metropolitan Area. The f...

Underground mining of coal seams in the Upper Silesian Coal Basin is currently performed under difficult geological and mining conditions. The mining depth, dislocations (faults and folds) and mining remnants are responsible for rockburst hazard in the highest degree. This hazard can be minimized by using active rockburst prevention, where destress...
