abstract = {The goal of the experiment was to verify the geoelectrical methods as a tool for detection of oil contaminations in soils and to monitor their bioremediation process. The survey area of approximately 2000 m2 is situated in the former military camp Borne Sulinowo in NW Poland. The area is covered by fluvioglacial sediments composed of sands and gravels with the first water level at the 11 12 m depth. Numerous shallow bore-holes were drilled to recognize the detailed geological structure. The measurements with conductivity meter (Geonics EM-31Mk2) and resistivity Lund Imaging System were carried out and soils samples were taken for laboratory tests in fall 2007. Then 70 litres of diesel fuel was spilled on the 3m2 area and in this way introduced into the soil. The geophysical measurements and laboratory tests were repeated. The measurements showed the distinct anomaly of resistivity or apparent conductivity related to oil contamination of soil. In order to carry out the bioremediation process the Yarrowia Lipolytica yeast were introduced into the contaminated soil in spring 2008. Then, the bioremediation was observed and monitored by EM, resistivity imaging measurements and laboratory tests of soil samples.},

abstract = {This paper presents the results of geophysical survey performed in the Pilawa River valley in the area of Middle Pomerania (Poland). The resistivity imaging method was applied. Resistivity profile measuring eight hundred metres allowed to investigate the geologic structure to the depth of 150 metres. The resistivity cross section shows the structure of Pleistocene sediments and the depth of Miocene - Pleistocene boundary. The significant lowering of the boundary is related to assumable ice-sheet margin range of Pomeranian phase of North Polish Glaciation. The lowering of the boundary may be a result of sediments compaction and the subglacial tunnel slope as well.},

abstract = {The survey has been carried out in the area the former military underground fuel base situated in the firing ground Borne Sulinowo (NW Poland). The oil contaminations were revealed in 7 zones in the studied area. In 2003 and 2005 yeast strain Yarrowia lipolytica A-101 suspensions were introduced into shallow boreholes to intensify the bioremediation process. In succeeding seasons the bioremediation was observed and monitored using EM and resistivity imaging measurements. The study showed the significant measurable change in soil electrical properties after several months since the yeast suspension had been introduced into hydrocarbons contaminated soil. The bioremediation can be efficiently observed and monitored with geoelectrical methods such as resistivity imaging or electromagnetic induction ones.},

abstract = {This paper presents the results of geoelectrical study of the former Zn-Pb processing waste-dump situated in the Olkusz region , southern Poland. In the past two kinds of waste were stored in this place. One is the washing waste, the other consists of tailings. A certain amount of them was processed in the first half of the 20th century. At present more than ten thousand tons remain on the stockyard. The results of the chemical analysis show that the contents of metals such as Zn, Pb, Cd and Tl exceed several orders of magnitude standards established for industrial soil. Under the low pH value mobility of these elements is significant. Unfavourable geological conditions can cause the migration into the underground water. In the study area the electromagnetical method was applied to study the boundaries between waste and unpolluted soil. The resistivity method was taken to define the vertical range of waste and to identify layers lying below the waste level. Our investigation points that geoelectrical methods can be successfully used for contouring Zn-Pb waste.},

abstract = {Focal mechanisms of 168 mining induced seismic events that occurred in the Halemba coal mine area (Upper Silesian Coal Basin; Poland) were determined using the seismic moment inversion method. 38 seismic events were studied in detail. For 12 tremors, non-double couple components were dominant in seismic moment tensor. Focal mechanisms of 38 tremors were repeatedly recalculated for gradually changing vertical Z coordinate values to obtain the maximum double couple seismic moment tensor component. The high value of non-shearing components in seismic moment tensor is probably a result of inaccurrate localization. The non-double couple mining induced seismic events are not so common in the USCB as previous studies suggested.},

abstract = {Focal mechanisms of 400 mining induced seismic events were determined using seismic moment tensor inversion method. The seismic moment tensors were calculated in time domain for P-wave first arrivals. All the seismic events were induced in the vicinity of one longwall opening localised in the Halemba coal mine area (Upper Silesian Coal Basin; Poland). Assuming that the tremors occurring in the same area in short time intervals are generated by similar stress conditions, mean local stress tensors for sets of seismic events were calculated. Only shearing focal mechanism seismic events were taken into account. The stress tensors were calculated for ten succeeding seismic events. The study showed that the state of stress was very unstable in the investigated area. Variation of the local stress field manifested itself by instantaneous interchanging of the positions of main stress axes. Variations of the state of stress were probably the result of mutual interaction of lithostatic, mining and tectonic stresses.},
