The term ‘geohazard’ is used to describe the natural and anthropogenic phenomena and processes taking place in the natural environment in the context of their negative influence on natural environment, including the geological one. The degree of geohazard is frequently evaluated on the basis of catalogued descriptions (activity of natural environment and human impact), which help identify particular hazards and ascribe them their value. According to Czech standards, 45 geohazards have been classified and described in detail in view of: geological knowledge, origin and way in which the hazard was evoked, geographical range, time, associated processes, social aspect and monitoring methods. Research works were conducted in a football stadium located in an area of underground hard coal extraction and surface production of raw minerals. The BAZALY stadium, where FC Banik Ostrava played its matches, is located in Ostrava in an area of former mining fields of Silesian Ostrava. These coal mines were closed in the 1990s, but even so they still create environmental hazards. The paper is devoted to research works and risk analysis of the environmental impact of mining activities, old workings and liquidated mines in terms of geohazard. The basic geohazard in the stadium area is methane migration from tectonically disturbed rock mass, also caused by incorrectly closed workings. Another hazard is associated with the increasing mining damage, i.e. tectonic movements, subsidence, local sinkholes, lowering groundwater level etc.

W pracy przedstawiono wyniki badań 98 archiwalnych map górniczych z rejonu Śląska. Wskazano na konieczność opracowania specjalnej mapy zasypanych szybów górniczych, która będzie pomocna w planach zagospodarowania przestrzennego terenów dawnego górnictwa kruszcowego i węglowego na ziemiach polskich. Analizowane mapy pozwoliły także stworzyć bazy historycznych pól górniczych, pozwalające odtwarzać stan własnościowy na danym terenie.

The research findings of 98 record copies of mining plans from the Silesia area were presented in this paper. It was drawn attention to the compilation of special purpose map for filled-in mining shafts which will be useful in the area development plans for areas of the former ore and coal mining on the Polish territories. The analyzed maps have enabled to create base of historical mining fields allowing for the reconstruction of information about ownership on the given premises.

W pracy przedstawiono podstawowe aspekty współpracy nawierzchni i autostradowych budowli ziemnych z deformującym się podłożem górniczym. Za najistotniejsze uznano zagadnienia redystrybucji składowych stanu naprężenia i odkształcenia w podłożu wynikające z jego chwilowej oraz długotrwałej utraty nośności. Wykazano, że efektywność wzmocnienia konstrukcji nawierzchni jest uzależniona od właściwego doboru wzmocnień geosyntetycznych.

Basic aspects of interrelation between pavement and earth structures of a motorway, and a deforming surface of a mining field are presented. As a most essential aspect is considered the problem of redistribution of components of the state of stress and/or deformation occurring in the sub-grade, resulting from transitory and sustained losses of loadcarrying capacity. Effectiveness of the pavement structure reinforcement depends on proper selection of geosynthetic reinforcement systems, concludes the paper.
